HRV4Training for Positive User Reviews

Useful!I use it every day.Version: 6.7.6

The best HRV tool yetI have previously used iTHLETE and heart strap HRV tools. The great advantage of HRV4training is that you do not require any tools (other than your phone and the app) to measure your heart rate and HRV. Plus it syncs nicely with Strava and TrainingPeaks as well as other activity trackers. It compares your data with other people sharing your gender, age and activity profile. Finally, and most importantly, if you write them a question, they respond immediately with clear guidance..Version: 6.6.5

Highly rated, simple, easy to use with actionable insights! Highly recommendedAbsolutely phenomenal app! Highly recommended to use as part of your morning routine to understand readiness! Excellent ability to track long term trends and results..Version: 8.1.6

Fantastic informationGreat App and excellent support when I had a problem. Can’t fault it!.Version: 7.5.2

The best Autoregulation tool you will useI am a competitive powerlifters and coach and I have to say this monitoring tool has been the best thing I have implemented into my training and my athletes training to measure fatigue. It has always been on the money as I also use a velocity tracker to measure bar speed in the gym. Highly recommended..Version: 6.2.7

Fantastic App for TrainingLots of data and sends info to TrainingPeaks. Great support from the creators for updates and help..Version: 6.9.3

Great app, great support!Avant-garde app that has become part of my daily routine for a year and a half. I use it to help plan my training, specifically whether I am in a sufficient condition to do my hard endurance workouts that day. Also, the makers are passionate runners who live and breathe their work plus offer great support. Thank you Marco and Ale!.Version: 7.0.9

Works greatNo strap. Tons of info from developer on HRV4Training. Tons of features, syncs with training peaks.Version: 6.9.3

Must have training appI have been through a lot of training apps and only a small handful remain on my phone. This is one of them. I wake every single day and use it. You're not going to govern your day by one app but I find this one is very insightful and combined with some other measure, it provides excellent data to help plan out training. Worth every cent..Version: 6.3.6

It’s not the training it’s the recovery that countsI’m loving this app!! Deceivingly simple to use. Incredibly useful insights. To get this level of physiological insight for $10 bucks is simply AMAZING. The fact that it can all be done with the phone you already have is downright awesome. Hats off to the developers!! Athletic improvement comes from stressing the body and then allowing the body to recover and adapt. The whole point of training is to give the body the maximum amount of training stress it can recover from before the next workout. But how much is too much? Training and life stress can accumulate in quite unintuitive ways. Especially over time. That’s what this app helps you to understand and it does it with a direct measurement of your particular physiological “state”, and then tracks that over time. I linked it to Strava and Training Peaks (super easy) to pull in workout data and now have a single point of reference for monitoring fatigue. Just great. If you want to optimize your training time and efforts this is absolutely the app to get. Incredible value for the $$..Version: 7.3.9

Easy to use and understandGot it based on the recommendation of a national cycling coach friend of mine. Have not been disappointed! I’ve been using it for just over a month now and really helps me understand how I’m feeling. Highly recommend!.Version: 7.7.9

Great appGreat app, made me faster..Version: 7.4.3

Solid. Super solid.Good interface with good features. Integration with Strava resolves the issue of only one workout per day 👍🏼. Best of all, and highly appreciated, is the responsiveness: I promote this app to people highlighting the readily open communication when emailing Support. That in itself is huge, plus the app itself is sophisticated and continuously updated..Version: 7.0.9

One of the bestI’ve tried several HRV apps and the developer really did their homework on this one. Lots of customization options and as technical or non technical as you’d like to get. Also amazing service and quick response with questions or trouble shooting. Product works great! Thanks.Version: 7.6.0

The best App to track your HRVI have tried three Apps to track my heart rate variability. I first tried HRV logger, which is by the same developer. That app is good but as I train competitively as a swimmer and cyclist I wanted specific features that applied to training. I find that this app has the features that I need..Version: 6.4.0

Don’t let the name fools youMeasuring HRV is just a small part of what the app does. It tracks training loads for you, integrates with Strava and TrainingPeaks, and provides you with a lot of training recommendations and statistics that other apps will charge you for monthly subscription fee..Version: 7.4.2

Love/Hate RelationshipThis app has changed my training for the better. I know I recover unusually quick but it’s hard to convince your coach without the data. This app has allowed me to train smarter and harder and on fewer rest days. The past two months, I’ve had a suggested take it easy day and it was spot on with how mentally and physically tired I was. However, the days when you get the ok to push hard is the best feeling. I love this app but it holds me accountable to really push or pull back when needed (hence the love/hate relationship)..Version: 7.3.6

Useful & value richThis app has been a daily companion of mine for many months to help me determine the optimal intensity of my workouts. I’ve used many devices that measure HRV and I find this quick and easy to use. I would also like to add that customer service is unsurpassed. Marco is incredibly responsive and helpful. Highly recommended for those who want to track HRV as one measure of physiological readiness..Version: 7.5.5

Unreliable readingHave been using the app for over a year on an iPhone X. Early versions of the app were much better at getting a reading. Something seems to have been changed in the latest version as it’s now really difficult to get a reading. It continually pauses and restarts when measuring and the heart rate that’s displayed is way off. I had the same issue a couple of months ago and the only way to resolve it was to remove and reinstall the app. That makes me think that it’s an issue with the app data that’s stored on the phone. And yes I do know how to properly cover the camera with my finger when measuring. Review updated June 2020: seems much more stable now. No problems for the last few months :).Version: 7.6.7

A must for anyone serious about fitnessI don’t usually write reviews, however, I felt obliged to leave a very positive review as this app is that good. I’ve only been using this app for a good month now and wish I got it years ago. I gym around 4 times a week and now having the insight into my recovery status has greatly helped me plan my workouts better and match my recovery status with the intensity of exercises I choose to so. I already see improvements in my performance from being able to choose my workout days better. In addition, this app is very very well made with continuous support by the developers, which also run a website that is regularly updated with new articles and research. I don’t think I’ve got any other app on my iPhone that is backed by more science than this one. I thought the price was a bit steep at first, but given the support and attention it receives from Marco and Alessandra I think they might be undercharging for it... Can I give this 10 stars?.Version: 7.1.4

You need a SMART hr monitorThis app provides excellent information in a format that is easy to read . I believe that as awareness of the medical world grows concerning the use of the many features that the app offers, a new paradigm will evolve around monitoring both physical and mental stress. The app is as useful to a therapist as it is a coach. Not only that it provides any health conscious person with a great way to monitor what their body is telling them. What you can' t monitor you can't manage!.Version: 5.0.4

You can’t manage what you don’t measureAfter reading and listening to Dan Plews on HRV and its application for athletes, my interest piqued and his recommendation was this app. I’ve been using it for 6-7mths now and it’s amazing. Marco and Alessandra have done and continue to do an amazing job with this platform, and I look forward to using it long into the future to better inform my day to day training and racing..Version: 6.9.8

Excellent appAs a runner, this app provides some really interesting insights. It’s frequently being updated to include new functions or metrics and it has been great value for money..Version: 7.0.9

Great app for performanceSolid data and interpretation for coaches and athletes. Highly recommend.Version: 7.0.9

Great AppI've been using this App for a few weeks and really like it. I only have a basic heart-rate monitor so use the camera - this works well for me. Unfortunately, after the update on 28th April I am unable to leave the HRV test screen once the test is complete. An alert slides up from the bottom of the screen but it contains no buttons and nothing else I do will allow me to get back to the home screen. On the plus side- the app UI layout is better. The new features look interesting but without being able to add new data I'll have to wait for a fix before I can assess them. I'm using an iPhone 4s with iOS 8.3.Version: 4.8.4

Fantastic HRV appI’ve been using this for about 5 months now, and am seeing some interesting insights into my training. Getting useful information out of HRV is tricky, and this app does a great job in helping you through this. But perhaps even more important are the resources provided alongside, which are well written, comprehensive and backed by scientific literature. Finally, the developers are very responsive to email, and after a recent query had a fix available within a few days. Thank you!.Version: 7.9.1

One of the very best apps for runnersNot usually a review writer. Happy to make an exception for HRV4Training. Had minor issue synchronising Strava data initally - a real (not auto-reply) response and attention to the email and problem within minutes. No issues since, and enjoy using the app. Updates with improved additional functions come through regularly. An app designed by a 'data nerd' (no offence Marco) average runner for all of us data nerd average, or otherwise, runners..Version: 6.7.3

Easy to useI have been tracking my HRV regularly using the camera and find the readings consistent. I like that it stores the results to Apple Health. I find using the tip of the finger not the pad gives consistent readings..Version: 7.6.4

Great HRV app!This app was just what I was looking for! It works great most the time, every now and then the app has troubles reading my HR with the camera but overall it’s very accurate and I’m very impressed!.Version: 7.1.1

HRV4 MetricsOne of the best training assistance tools that I’ve used. It takes time to build up all of the information that the app needs to help track training evolutions, but the process helped to keep me on a regular schedule as I prepared for upcoming events. A great method for tracking a range of objective and subjective information as I train..Version: 7.1.9

Amazing App for Monitoring Your Health and StressI am now a two year user of this app. Initially I used this app and two other HRV tracking apps, but have long since deleted the others and rely on this and Marco’s HRV Logger for HRV. I’ve used it with the camera, a Polar H10 strap and now in combination with an Oura ring. Always accurate results, but more importantly, solid training perspective on how ready I am to really push myself. The app seems to know my readiness to perform better than I sense it myself, which I find amazing. Only improvement I can think of is that it needs a category for athletes older than the “50 and older” for those of us very senior athletes. Best HRV app available..Version: 7.7.7

Really impressedHope to add more comments as I get more data but up to now very pleased with capability of app and how rMSSD relates to how I feel on a given day. The tags are very useful for interpreting your readings and shouldn’t be overlooked..Version: 6.9.9

An app i can trustHRV4Training is a scientifically valid, highly accurate fitness, health and heart data app that ticks all my boxes. The app dev’s - Marco and Alessandra - are highly qualified, committed, proactive and professional. HRV4Training quickly gathers all your metrics and produces relevant, easily understood raw and correlated information, helping both athletes and those managing fatiguing conditions. The app is adaptive, improving as you log more data, and packs a deceptively immense amount of useful information. It’s the only HRV app I trust..Version: 7.0.4

IPhone 6s Plus problem...I use this app every morning , it's really useful for monitoring how I'm responding to training. I've just got an iPhone 6s Plus and am having trouble looking back at the data in the "baseline" section. The tabs that normally run along the top have disappeared so I can't flick between the different measures. Any ideas if there's anything I can do to get this back? Or is it a bug with the bigger screen? Thanks for a great app! :).Version: 6.1.4

Essential tool for monitoring trainingI have been using this app now since the start of the year. It is easy to use and has worked flawlessly. The data is well presented and explained, integration with other platforms and training tools is seamless and easy to configure. It's really helped to gauge me training levels and planning..Version: 6.7.6

ExcellentAccurate (I use a polar HRM but it’s good without). Lots of metrics and analysis. Including VO2max. Great integration with a wide range of 3rd party apps (I use TrainingPeaks). Written by someone who knows what they are doing. I am very pleased with it. And the support is excellent too..Version: 7.7.7

Easy and deepEasy to use and informative, integrates with Strava and TP, could be the missing piece in the training puzzle..Version: 7.4.3

Love thisI was skeptical that a camera heat rate app could measure my HRV reliably, but given the lack of other means to do so right as I wake up in the morning, I decided to gamble on this app. I'm not disappointed at all. I've found it to accurately identify when I'm not quite up to strenuous training, a few times telling me when I didn't know (I ran anyway and performed terribly). I live and train by numbers, and this app has provided me another great metric to aid me in my running endeavors..Version: 6.9.3

Fantastic AppMy brother got me into using this and it's amazing that it can track so much about your day and your outcomes based on your heart rate variability. Highly useful !.Version: 6.6.9

Excellent training tool with unique measurementHaving used this for the best part of a year after researching the HRV concept and the numerous tools available, HRV4Training has become an essential part of my triathlon programme. Extensive and informative data, practical and visual format, as well as integrated measurement makes this ideal and invaluable..Version: 6.8.5

The right fitI have found the frequent updates, add ones and enhanced functionality to be in line with what I’m looking for from an HRV app. I would and have been recommending this app to anyone I interested in knowing how their HR variability is doing as it is the BEST indicator of overtraining available. Great app, easy to use and always improving - whats not to love..Version: 7.3.0

Hrv4Great app. I like the visible heart rate option while measuring and the ability to use my iPhone camera and light to read is amazing . Great tool for getting trading trends and to see how your body responds to different training loads. Subjective feel is not always 100% so this helps me back up my self diagnosis..Version: 7.0.0

Excellent training aidProvides simple to understand and relevant information. Just need to be able to add more than one sport on each day for multiple training sessions.Version: 6.7.7

Brilliant appHRV is finnaly becoming accessible to the masses. We are lucky that clever and generous experts like Marco have created such an app. If you want to scientifically learn more about your heart fitness and how to optimise your training this is a super app to get. I love the population comparison data and abilty to tag your HRV readings to your needs. I personally find using a chest strap more reliable for taking HRV readings with this app but its nice to know that I can fall back on simply using my iphone to take a reading if I forget to take my chest strap with me when I travel.Version: 6.6.5

Great health toolVery useful app for anyone wanting to improve there fitness level or general health! Lots of information to read about and help you get on track to living a more active life!.Version: 7.0.2

Great AppI have found this app very easy to use and it provides usefull information on fitness/health trends over a period of time as well as an early warning when your sympathetic nervous system is under stress. The background information provided and support are excellent also..Version: 6.8.9

Best HRV app on the marketI currently use four HRV apps on a daily basis: HRV+ (free), Elite HRV (free), ithlete (paid app and ongoing subscription) and HRV4Training (paid app). I use four apps for cross validation and interpretation of the readings (e.g., if only one out of four readings says my HRV is a bit low it may just be a problematic reading whereas if three or all four apps agree that my HRV is low then I'll take it easy). My sport is Triathlon and I typically train between four and five days per week (i.e., running, swimming, cycling and strength/conditioning training). HRV4 training offers the most indepth interpretation and analysis off all the apps. It does this with no ongoing subscription which I like. I particularly like the analysis of training load (to explore whether you are likely to be losing fitness or at risk of injury) and trend analysis (to see how you are coping with adjustments to training over time). HRV4Training's recommendations are also weighted by your subjective scores (e.g., motivation, fatigue etc) which I've learnt always helps to interpret your HRV score and use to base your decision on whether to train on a given day. The supporting website is also really informative and updated regularly with peer reviewed articles you can read yourself. I like this evidence-based and scientific approach. I liked to app so much I purchased a polar H7 heart rate monitor as I find it much easier and more practical to take readings using this, although the camera method still seems to work fine. Recommendations I would suggest for improvement (that I find useful on other apps) are guided breathing (i.e., an image of a circle that expands/contracts to indicate when to inhale/exhale when taking a reading for more consistent measurements), an analysis of whether the sympathetic or parasympathetic nervous system is more active following a reading and the opportunity to get some "live", visual biofeedback of your HRV to use the app when doing mindfulness meditation exercises for example. The absence of these things really don't take anything away from the app though so I would say that if you're only going to spend money on one HRV app, spend it on this this one (i.e., HRV4 training)!.Version: 7.0.8

Great tool for every athleteI used to rely purely on HR data however I would still get injuries or sickness seemingly out of nowhere. It turns out that If you train hard your HR can be lower OR higher so you may not be recovered when you think you are. Since using HRV I’ve been much better on my recovery and been improving for the last 4 months without any setbacks. Kudos to the team behind this awesome app!.Version: 7.1.4

Training metrics on a higher levelJust getting into this but I believe this could take my training to a higher level..Version: 6.7.5

Very comprehensive and usefulI’m very impressed by the insights obtained with this app. Every morning it suggests whether to train as planned or to take it a little easier based on my HRV. I have found the suggestions are really helpful as I tend to train too hard sometimes. I also really like the algorithm it uses to calculate VO2max. I find it more accurate and reliable than what the Apple Watch uses..Version: 7.9.1

Performance of app and supportI don’t usually write reviews but the performance and support of this app is so above normal that I think it deserves noting. Along with supplying an app that works very well, there is a full complement of links to connect you to the technical literature on the metrics that are being measured. You don’t need it to use the app but it’s there if you want. And it’s current research, not just random things from 5+ years ago. The support is also outstanding. I had a small problem with the camera and got feedback in an hour that solved it. These are serious people that provide links to the latest in fitness research and support an app that provides potentially very useful biometric feedback on where your body is at in your training cycle. Get this app. It’s very good..Version: 7.4.2

A huge depth of informationI’ve been utilising the app for 2 weeks now and it has been hugely beneficial in reading the stress on my body and whether I should train Hard or easy each day. I can highly recommend this to sports men or women who are interested in tracking HRV for training needs. All the while I have been managing elevated cortisol and again, the app has more than improved my health by allowing me to measure the internal signal and confirm how I feel day to day. A great app and one I’ll never be without. Thanks!.Version: 7.1.4

An athletes best friendBeing an athlete tracking anything related to my health and performance is important. Being able to match how I feel with the results of the HR scan is very helpful so I know I'm not psyching out of a session if I genuinely feel run down or tired it shows in how high my resting HR is. Very helpful! Still getting the hang of using the app but it's great I love it.Version: 6.8.1

Outstanding app and developerI have been using the app daily for over a year. Helped me identify factors limiting sleep and recovery. Assisted me with recovery from surgery. Three days ago it quit working. Sent an email to developer. He answered same day. His proposed solution did not work. Sent another email. Again got a same-day reply. This time solution worked. Lost no data, recouped the data from the last three days as well! Highly recommend app, associated blog and science, and the developer..Version: 7.7.7

Excellent app for athletesEasy to use, and very informative. Definitely useful for determining the day's work out, and also indicative of how your performance will turn out..Version: 6.4.2

Excellent!This HRV app is Very straightforward to use to record daily morning HR and HRV. It has lots of great built in options to explore the data wrt training and daily other stresses (e.g. Travel). The data set is also exportable too, which is really excellent if you want the raw data to do your own analysis..Version: 6.8.3

Great appI used to use something else to track hrv but felt weird wearing basically two watches, now I can measure it without that. Really glad that it links with Strava so any work out I do there is transposed hassle free. The UI is a little hard to figure out but I think I’m getting the hang of it..Version: 7.3.7

Do not take all workouts into account *Fixed*The app retrieve only workouts as biking or running. So when you are mostly training at the gym the charts are almost useless because the app never gets your HR even you are wearing an H10. You can enter the total TSS manually but in that case you cannot differentiate sports. So if you have done biking, rowing, spinning and dancing the same day, you’re screwed. The basic feature is working fine, but all the insights are useless if your doing something else than biking or running. Edit: The app is since the last update importing all workouts from TP, even categorized as *others* which means you no longer have to manually calculate your daily TSS to get your overall score. This is much more comfortable and accurate since all the workouts end up listed. However there’s seems to be a bug since the total time is incorrect, it takes only one workout into account and I have to manually calculate it, this part is probably coded as a separate and not updated method..Version: 7.2.7

Runner/biker/skierGreat app...I do not have an iphone so I use it with a bluetooth HR monitor strap since the camera based method only works on iphones that have a flash. Easy to use and links with strava, sport tracks and other training programs. Provides interesting insights into relationship between HRV and various training metrics..Version: 6.6.5

Indispensable training toolI’ve been using HRV4Training daily for almost a year now to track my heart rate and many other aspects of my health, life, and training. The app has become an indispensable part of my training process. HRV4Training is based on reviewed, validated research, and Marco uses his personal expertise and his experience as a serious runner to make the app focused and effective. His blog posts about the workings of the app and the science behind it are a tremendous resource. And he’s been unbelievably available in answering questions and helping me fine-tune my usage of the app..Version: 6.9.8

ExcellentGreat app, easy to use with lots of explanations about it's various features. A nice little tool for my training and wellbeing toolkit..Version: 6.5.9

Measurement using cameraI love this app and would like to see the hrv measurement using the camera further improved. Recently I have to repeat the measurement quite often due to signal poor or not optimal with great variability in the result. It looks like that the amount of pressure applied during measurement has an impact. I love to help futher improving it if possible..Version: 7.6.3

I love this app !Not only is it super easy to use, it also constantly gets updated and improved..Version: 6.5.4

Makes consistent measurements easyGreat app, makes it really easy to take an HRV measure when you wake up in the morning so you’re much more likely to do it regularly and can get a better idea of trends. He been very helpful in managing mental, lifestyle and training stress during the current pandemic..Version: 7.6.3

Great training toolThis is an awesome, easy to use tool to help plan training. Use it to train around my shift work schedule. Takes into account not only training but fatigue from working long night shifts..Version: 6.2.8

Best HRV app out thereThis one really simplifies things for you after you get a baseline for yourself. However, it has the depth to really dive deep into if you are into it. Simply take a reading when you wake, (only save quality readings, if it says that it’s not reliable, take another) answer a few questions and that’s it!.Version: 7.5.2

Great app & evolving/developing rapidlyFurther positive developments. The app now bases it's daily training recommendation on a combination of HRV and the trend of your subjective markers. This seems to be uncannily accurate for me. The measurement method is quick and easy - the best I've used. Any issues with the app are fixed really quickly and developer is very open to comments and suggestions. The app just keeps improving and is user-friendly but underpinned by scientific rigour. Well worth the money..Version: 6.3.9

Not just for athletes!Provides accurate data to help me manage pacing and energy expenditure with ME/CFS and it’s so much easier than using a chest strap first thing in the morning. The custom tags let me correlate good or bad days with other factors. With its scientific validity and responsive dev team this is money very well spent..Version: 7.1.3

Brilliant, flexible and very practical.I’ve tried several HRV apps, this is by far the best and well worth the money. I just wish I had come across this first. It even works with the Corsense finger sensor (which another HRV app developer refuses to support.) I wrote to the developer asking if it’s possible to include readings from a Bluetooth pulse oximeter (Wellue). I’m not putting too much hope on this as it has its own app on the istore. It’s just that I would like to keep all my readings in one basket if possible. Again, well done to the developer on creating this great app!.Version: 7.7.7

User for over a year. Really solid training toolI track my HRV every morning and use it to base my training off of. Has been really helpful to see the effects of training load and prevent overtraining.Version: 8.0.5

Great!Fantastic app! Well designed and useful for both athlete and coach. Not just an app for daily HRV but also training stress and well designed analysis. Finally, excellent service/support by the creator who clearly is a scientist as well as designer. Keep up the good work!.Version: 6.0.7

A must for endurance athleteThat app was a game changer for me like a runner. It helps me to adjust my training cycles and place my intervals session in the week..Version: 7.6.8

The best app out there for HRV!What can I say I’m impressed. I’ve tested and downloaded several other HRV apps but they either required an external or didn’t support the new Apple Watch feature that supports HRV. Even though this app doesn’t support the Apple Watch either, it still offered the ability to use my existing iPhone. Don’t be fooled, the iPhone camera works just as great. I used to use the camera for other things to measure HR and I found it to be just as accurate. The HRV was spot on at least referencing against the Apple Watch readings. As for the app, there are some bugs that I’ve worked with Marco to resolve so while minor he has worked with me. I do acknowledge that most of these HRV apps tend to favor runners, cyclists, or triathletes. Fitness and CrossFit folks are just as interested in peak training. Remember us too! Lastly, the insights are great and this is the kind of easy advice I was looking for. Integration with other apps to include Strava and Training Peaks is a plus. A negative is the inability to get into the weeds with your data or edit but I just found out they have a Coach app that will allow you to do that and I might have to investigate that! Overall very impressed and hope they keep developing this app..Version: 6.9.5

Probably the best option.I would recommend this app to everyone. I sold my whoop to use this app and even though I just bought a new garmin watch I still take my reading in this app and camera every morning. It's funny how this little app seems to do more than what these huge companies can do..Version: 8.1.0

Excellent for analyticsReally useful and accurate features, fantastic app especially now with Apple Watch integration..Version: 7.3.3

Fabulous appI read about this app in Dr Rangan Chatterjee’s book ‘The Stress Solution’. It’s a great app and I’m getting clear sense of where I’m at before I start a new training cycle..Version: 7.3.9

Invaluable training toolHave been using this app daily for over 3 months now. The daily results from this app are invaluable if you want to step up your training to the next level. If I get a low rMSSD value then I know to back off my session for that day. On the flip side if I was planning a recovery run and I get a higher score then I know I'm good to go for a intense workout. So many times in the first few months I didn't take heed of my results always ended with a failed session if my scores were low. Now I know when to put in a hard run and when to hold back. Fantastic app..Version: 6.7.2

Great AppFantastic app! Information is great and any questions or queries I have are answered quickly! Fantastic support! Thank you!.Version: 6.3.1

Just works-quick and easyNo fumbling for your chest strap in the morning, grab your phone, take a measurement and go. Enough options to play with but the basic settings give me everything I need. Thanks and keep up the good work!.Version: 5.1.7

Simple and easy to useSuch a simple app to use with powerful info at your fingertips..Version: 7.3.7

Great app from a passionate developerGreat way to track your HRV without the need for additional hardware. If you doubt that it is possible to get accurate HRV data using your phone's camera, then definitely check out the author's blog where he dives deep into the science, and demonstrates his methodology and reasoning. Usage requires only 1 minute every morning, and the data pays off as you collect more and the app is able to compile more insights. Data is also exportable if you want to do your own analysis. While there are a few ui quirks, I am still confident in giving it 5 stars, due to the developer's consistent improvement of the app over the years, and responsive customer support and blog..Version: 6.2.8

Keeps getting better, encourages me to get betterIt's a great application for training and racing. It's continually improved and makes a complex physiological assessment straightforward. It has pushed me to train harder and I've listened to it for extra rest days when I'm over the line. I gave it -1 star because I've always been annoyed that the daily subjective text input (annotations) don't autocorrect - which is essential on such tiny keyboards..Version: 6.5.4

Simple to useThe app creator has a wealth of knowledge about HRV and his blog is a great read..Version: 6.3.8

Absolutely amazing!These capabilities are being sold for hundreds of dollars by other third parties as isolated applications. This app is absolutely brilliant and works flawlessly. The integrations with Strava and other apps are a amazing. In addition to an amazing app, the web site and author a a wealth of knowledge. Their support is unparalleled! Any serious or recreational athlete will benefit tremendously from this app..Version: 6.2.9

Brilliant appI've been using this every day for 2 months. It's both easy to use, and packed full of thoughtful, interesting features & analysis. Clearly the app developers are very well informed about HRV, very smart & passionate about the subject & its potential for enhancing training, health & wellbeing. My only gripe is that the emphasis of the app (like all HRV apps as far as I can tell) is very much on using it as a tool for athletic performance, whereas my own personal interest is in HRV as an indicator of mental wellbeing- & actually using HRV exercises as a means to improve HRV & therefore mental wellbeing over time. For the same reason, it's a shame that the latest version has lost the paced breathing exercise, as this is a crucial part of HRV training. (There is evidence that timing ones breaths precisely to match the frequency of the baroreflex function has a kind of feedback effect causing HRV to increase significantly). Please can you bring it back as an option?.Version: 6.5.3

Awesome Support ResponseOver the last couple years I’ve found it necessary to contact support only twice when I upgraded to a new iPhone. Marco responded to my questions within hours on one occasion, and literally a few minutes on this recent occasion. The response was not only super fast, but with suggestions that worked to solve my problem..Version: 7.1.7

Amazing, actionable insightsAdding heart rate variability to my fitness and health toolkit has been invaluable, and after trying many of the different tools on the market I’ve found this the beat by far - rich data analytics that offer actionable suggestions..Version: 7.7.8

A great additional metrixLike all measurements, HRV adds another view of your body’s response to stress. With this app it is easy to take the measurements, providing you data that has not been easily available. Easy connectivity to all your apps. Highly recommend.....Version: 7.2.7

Great AppUsing regularly to help with my indoor rowing and weights. Key issue is to adapt your training to the advice - else why use it - but if you do it really helps..Version: 7.1.1

The best HRV app for iOSFantastic app. The go-to HRV app in my opinion. Works flawlessly. Constant development and updates show how much work Marco puts into this! Well worth the money..Version: 6.2.9

Essential for serious athletesThis app takes away the subjective nature of hard / easy training and provides athletes with a powerful tool to maximise performance..Version: 6.2.6

Excellent AppGreat app with clearly expert advice and guidance. Ready to use and first class support. Very happy with my purchase..Version: 7.3.7

Awesome app with great functionality!Great!.Version: 6.5.4

Simple to use, complex data made easyThis app is absolutely excellent. Simple to use each morning with Apple Watch or just your finger on the camera. Gives all the information you require to make your training and rest plan the best possible for your individual needs. Even better is that it gives this information without any weird proprietary algorithms messing with your data..Version: 8.0.1

Great AppHave just started using this App - recommendation from Dr Rangan Chattergee (Four Pillar Plan author). Experimenting with HRV for stress management..Version: 7.4.0

Very helpful app for monitoring HRV and trainingI've been using this for a few weeks now to measure HRV and my training. It nicely integrates with most platforms I use like Strava and Apple Health, and provides me with a helpful measure to inform my training. Updates happen pretty regularly with the app too. While I like the app information, I do think some of the visualizations could be improved to better communicate not just the resulting data, but actions you should take next based on the data..Version: 6.8.9

Great App. Well thought outCleverly done. This app provides a thorough overview of your data trends over time to assist in decision making for your training & lifestyle choices.Version: 7.0.9

Super quick customer serviceGreat app and pulled my training into the 21st century. Super quick cudtomer service response at their email address when had question..Version: 7.3.8

Great Even For Non-Elite AthleteI’m a moderate exerciser, walk, hike, weight lifting, yoga, Pilates, but I tend to over do on occasion and wreck myself. I’ve been using this App since it first came out almost every morning. It will advise to either Proceed, Limit Intensity, or Take It Easy. I’ve learned the hard way to follow the advice and have avoided injury or sickness. Very easy to use..Version: 8.0.6

Top app, elegant, features, SCIENCE!A great app which combined with a good training plan has allowed me to monitor scientifically my training progress and where necessary make ‘overtraining’ or ‘unproductive training’ adjustments. Combined with Training Peaks, this has transformed my MTB endurance training with a steady consistent fitness ramp and no stress injuries or over tiredness!! There’s more science/analysis here than I’ll ever need and let’s face it who doesn’t love a pretty graph! I even referred a bug back to the developers, had an immediate response and a fix in a couple of days. What’s not to like!!! EXCELLENT. (If only all apps were as good and well supported as this!?).Version: 7.0.9

ExcellentThis is excellent, as is the camera app by the same company. No need for a sensor which have always caused me problems, easy to use and great recording stats. Thanks a lot for a great product and a bargain price considering the valuable health information it contains. A bit annoyed I spent £50 on a rubbish finger sensor and extra money for an app from another company! Cheers Tony.Version: 6.3.5

Marco is bossA great app just hit the top shelf. Great work, sir..Version: 6.0

Very good appBravo for the research that led to the creation of the app..Version: 6.5.0

Great appAwesome app. Camera based reading is much more interesting when I wake up than putting on my hrm strap. Lots of way to see the data, good analysis, and if you look at the app website, you'll see that the author really care and is passionate about HRV.Version: 6.7.1

Easy, lots of insightsThis app has helped me understand fatigue levels in ways I’ve never seen before. That’s the stated goal of the app. Even better, I’ve been pleasantly surprised at how it has also served as an accountability tool. Just by using it I’ve done other things to improve my sleep, which then gives more accurate HR readings the next morning. Definitely try it and if you need help interpreting the more complicated metrics then get a coach for a while..Version: 6.9.5

Learning so muchI’ve only just gotten started collecting data with this app but I am already leaning so much and finding it all so interesting. At first I felt a little bit overwhelmed by all of the options for analysis but it looks like they unlock at different times as enough data is available. I’m really looking forward to digging into it all..Version: 7.2.4

Great HRV solutionI did a little research before choosing this as an HRV tracking/monitoring solution, and feel it is the perfect option for me. I am constantly finding more data and insights available within the app, beyond what is required for simply knowing whether it’s a good day to “train hard” or not. The maker/founder seems reputable and the app itself is very well designed..Version: 7.2.1

InsightfulWhat I like about this app is the clarity surrounding explaining what can be a very complicated subject. You do not need a medical degree and you do not need to Google everything as it is all set out in simple plain English for all to see, read and understand. If you do have a question the support is excellent as you get a reply very quickly. The function of this app is to help you live a healthier life by monitoring and comprehending how your heart is coping with your lifestyle and it succeeds in doing just that..Version: 7.3.0

HRV4Training and the hrvlogger appsThese apps are a must for anyone who takes their hrv measurements seriously. Marco has taken the time to carefully research and place his findings successfully in peer reviewed journals, can’t be said for most apps! If you value the science go with HRV4Training and hrvlogger for validated interpretation of your data..Version: 7.3.0

10 days of use and I’m pleasedA doctor recommended this to me to use with the camera sensor. So far it seems to correspond to my heart rate on a garmin fénix and also to my fatigue and stress level. The graphs are easy to understand. I haven’t had enough measurements to comment on the analysis feature. I wish it had the ability to take multiple readings during the day to taker a finer look at how exertion, foods, and stressors effect you in real time..Version: 7.6.0

No need for Oura or Whoop!I have been looking for something to help me with my training and four months I have been debating the loop and the aura ring. Luckily I found this app it is exactly what someone with an Apple or Apple Watch needs! I’m not even a month into it and it’s already starting to learn how I train and provide guidance to optimize my training. And with the latest upgrade to take in Apple Watch and health data it’s even more useful. Don’t be scared by how much it cost it’s worth it!! I have paid for & tried pretty much every HRV app available and this is the only one that now lives on my phone. The only thing that could make this app better would be if it took the sleep data from your Apple Watch combined it with the HRV data and gave you recovery and training guidance..Version: 7.7.1

Best app on HRV appI have used as a coach with athletes for endurance sport for many years. It works very well and is a low cost solution . It is research validated and syncs with training peaks . The ability to add notes and subjective measures to hrv/hr makes it superior to many other apps.Version: 7.7.7

Thriving app, great features and experienceI’ve been using the app to track my HRV daily for many months now. I use it in many ways and it’s provided some fascinating insight. For instance when I’ve tried a change in diet I’ve been able to see very clear and rapid feedback in the HRV baseline view that it’s doing me some good. When I ran an ultra marathon that took me 22 hours, I could see my recovery progress over the next few weeks in the chart. I love the dedicated team behind the app. It’s wonderful to see the lengths they go to to establish technical validity of the method. They’ve replied to my messages several times. The blog posts are always fascinating and helpful. I’m also impressed by the company they keep, they’ve been mentioned recently by for instance the guys at Nourish Balance Thrive and also Alex Ferretti. I’m confident I’ll be a happy customer for as long as they keep this going..Version: 6.9.6

They love what they doThis app is continually updated and improved. Excellent app for anyone into fitness..Version: 6.8.1

Lots of data, great executionDaily use for almost 3 months. Data can be very useful to reflect on how certain training periods went and to some extent can be used to shape future training. This app makes it easy to track what was a traditionally hard to track metric and presents it in a very easy to view manner..Version: 6.8.3

Good for a baselineThe app is good for a baseline and general idea of HRV. I do find it to be accurate and convenient to use. I try and use it as soon as I wake up before I am out of bed in the morning. I think being consistent in time of day and with how you position the phone is essential to getting a good measurement. I wish you could do multiple measurements per day (AM and PM). Overall a good app!.Version: 7.4.7

Love the appLove that you can get into the science if you want to, or just have it tell what's going on in plain English..Version: 6.6.5

Game changerSimple to use and proves actionable insight. How you feel is not always a great indicator. Rather than just push through tough workouts I may swap them for a light yoga session however the app also indicates when to dig deep. The guidance and trends that the app provide gives an individual the intel to really take things to the next step. Thoroughly recommend..Version: 7.2.7

Very good app for age groupersSuch a great tool for managing training loads. Personally I use it with training peaks and it works wonders..Version: 7.0.1

Excellent long term appI bought this app years ago and the data it has give me over the years is invaluable. Definitely recommend. Started off using the camera, and now have a chest heart rate monitor, both worked very well. My only feature wish is to be able to delete historical data beyond a certain date..Version: 7.6.8

Amazing appI've been using this app to accent my run training for about 3 months now and it keeps getting better and better. Absolutely love this company..Version: 6.3.6

Really good AppBeen using the apps for 2+ years, solid and a must have if you value your training and physical condition.Version: 7.7.1

Very accurate, most used tool for CyclingI have had every single iphone from day one, $$$ spent on apps and this is the first review I have bothered writing. It has helped my training which I take very seriously. No more guess work. First thing I do every morning. Thank you for developing it. Looking forward for more of your work. I tried the other HRV apps and they are childish compared to this one. You MUST try it..Version: 6.1.4

Very powerful, regularly updatedThis is a fantastic app that I use everyday. It's powerful analytics help shape my training and have lead to a deeper understanding of how my body copes with any type of load I can think off. Incredible value and regularly updated, this app gets better and better. Thanks Marco!.Version: 6.7.4

Consistency is great!Maybe I'll have to start running again!!.Version: 7.1.3

Good but one suggestionI like the app, but one suggestion: Don’t put such a short time limit on obtaining data from Apple. Sometimes I forget to sync with the HRV4T app until later in the day, by which the app refuses to read it as it doesn’t find an entry in the past 3 hours. I know how to delete more recent entries to ensure the right data are used..Version: 7.7.7

The HRV sports appIf you measure HRV and compete in sports then this is the app for you. Each update brings more innovation and insights. Highly recommended with great support from the developers. 👍.Version: 7.1.0

Superb app with superb communication from developers!An excellent well rounded app that you can tell true care attention and professionalism has gone in to! The research is in depth and robust and you can have high confidence that this isn't just a gimmick! The HRV trends I have measured have really helped guide my training and can feel the benefits of training using the guidance and trends highlighted!.Version: 6.7.7

My Go-to Training AppThis is my go-to training app! It is super accurate and provides loads of useful data if you are serious about performance, or even as a tool to help you get, and then more importantly, stay in excellent shape. It has been so accurate as to provide hints when I’ve needed to back off of training and recover, while I was on the brink of catching a common cold! Pretty amazing software..Version: 7.1.3

Important fitness companionThis app has been a phenomenal resource for me as I venture into higher levels of fitness. Being able to track trends and know when it’s time to push harder or take it easy is tremendously valuable. This app isn’t for someone that just wants a friendly motivator to work out, it’s for someone that is already motivated and wants another tool to continue to improve their fitness..Version: 7.9.3

Love itI'm a numbers guy and this app has numbers out the wazoo. The science behind it is, in my opinion, well supported and the outputs from the app correlate well with more traditional HRV monitors (I use a FR910 and Firstbeat). Definitely worth the $$ if you like to use numbers to improve training efficiency. No stability issues for me..Version: 4.8.0

Interesting though I haven’t figured out how to use the correlation yetI get good hr readings from this, and I like being able to track correlating events/data, including subjective/qualitative data points. However I still haven’t figured out how to turn those data into something actionable..Version: 7.5.2

Brilliant!I use this app. I mean i actually use this every day. Other apps are a chore for me. This is No fuss, i own other HRV apps and straps and receivers - this app and the others in the bundle are great value. The data seems as accurate as any other i have used. Support for my questions has been excellent. Check you health - buy this app..Version: 5.1.2

ExceptionalI did all the research on every HRV solution I could find before selecting HRV4 training, and so far I'm delighted. It was the blog that sold me as the team clearly shows their passion for ongoing research into the topic of recovery tracking. I do have an external H7 monitor, but after reading one of those blogs I gave up needing the monitor and switched to the camera, with the shortened 1 min test. It took a couple practices to get it to optimal readings, but they had a practice screen until I figured out how to hold it for the best results. Loving the research backed analysis in a clean well designed app. Would love to do readings more than once a day, but as they've spelled out from the research, variability can be high from minute to minute making the once a day in a duplicatable setting approach the most effective for understanding the trends..Version: 6.6.7

The best for HRVI use this app every day and I think it’s the best. I do find it difficult to read some of the UI controls when in light mode so I use dark instead Unfortunately the App doesn’t automatically chance from light to dark like lost others do. Would be nice if the Apple Watch was better supported too!.Version: 7.7.7

Awesome app!!I use this app for health purposes (not training per se) and have found the daily results accurately reflect my health status. This has become a valuable tool in helping me predict when I am needing to slow down, rest, or when I can actually push my body cardiovascularily. For those plagued with “crashing” this can add a some reassurance to a life that is otherwise fraught with endless unpredictable challenges. Huge learning curve—not on using the app— but with HRV theory itself, and how it impacts health..Version: 7.1.6

Superb, informative App with excellent support.Running between 45 and 80 miles per week, accurate HRV data provides valuable insight into levels of fatigue and optimal training conditions. Looking forward to accessing further insights as data accumulates, such as chronic/acute training load, VO2 Max estimations, polarization and lactate threshold [to name a few]. Definitely useful for the non athlete too, or in times of rest/off-season [Stress comes in many forms] Excellent, and prompt support from the founder…. on a Sunday! A refreshing change to find someone passionate and committed to their business..Version: 7.4.2

A fantastic toolThis is an amazingly useful app for tracking your HRV. In particular, this app unlocks the ability to collect HRV for anyone with an iPhone. HRV is a fantastic biofeedback indicator that everyone should be tracking. Especially now during the Corona Virus outbreak, I monitor my HRV daily for signs of immunity imbalance, as part of an advanced biofeedback monitoring and supplementation regime, so I can take steps to not get sick. Accounting for other variables that contribute to reduction in HRV, I’ve noticed I can get at least a 12-24 hr warning signal in advance of feeling symptoms. The app does require some diligence taking your HRV readings and grabbing them from Apple Health. Apple doesn’t make it easy and clearly hasn’t figured out how important HRV is yet. But that’s not the developers fault. I personally take readings using my Apple Watch, and do a 3 minute session with the breath app to get the HRV reading..Version: 7.6.2

Time crunched dadAs a sleep deprived dad of 3, knowing when to train hard or take it easy is important for me so I don't make myself ill. This app takes the guesswork out of it and helps structure your daily/weekly training intensity. Read the blog for great tips and further details. First class support from developer as well. Fantastic value!.Version: 5.2.0

Best HRV app for daily trackingThis app is the best HRV app for daily HRV measurement for training and general health. Lots of cool features comparing various aspects of physical well being with your HR data. It's regularly updated with useful changes every time. Thanks guys!.Version: 6.0.9
