Blood Oxygen App for Negative User Reviews

Doesn’t let me press the cross on the free trial pageIt doesn’t let me to press the cross on the free trial page.Version: 1.2.21

Not worth $25This app only gathers information that is already free within my iWatch. It doesn’t do anything new or different or better. All it does is log and display it differently. The required watch face is nearly useless to me. I would never waste money on this again..Version: 2.24.0

Don't download this appI want to use blood oxygen function on Apple watch so i download this app and think that it is developed by Apple. It is NOT from Apple. You could find the blood oxygen app from Apple watch directly This app do not give you exact oxygen number, so it is just trash. You don't need it since you could get oxygen data from Health and you could measure exact oxygen number from Apple watch.Version: 2.10.0

LIES! Doesn’t Check Blood OxygenIn the sign up for the premium service ($20 a year) it literally says “forget the apple watch 6/7”…..which would lead ANYONE to believe you do NOT need an Apple Watch 6/7 to use this feature. Then I read the developer responses to reviews and they say it can only work with the Apple Watch 6/7 for blood oxygen. Seriously? Maybe you wouldn’t get bad reviews if you were HONEST about it from the jump. I cancelled my free trial..Version: 1.2.23

Blood oxygenCannot get a reading for blood oxygen ! Today, I just subscribed for one year. But cannot get a reading for blood oxygen. My Apple Watch is OS 6.3! So I find this app not useful at all!! How to get the refund or any guidance to use this! This is frustrating now!!!.Version: 1.2.10

No oxygenDoes not measure oxygen level. This is synced to my Apple Watch . Nothing comes up on the app on the watch- blank screen. No good and waste of time.Version: 1.2.11

This is a poor appI have an Apple Watch, it is connected to apple health and I wanted this app to MEASURE my oxygen level and add it to my sol apple health data, but actually it is just for putting your data in - you need an actual oxymeter to do the measuring. Very poor, don’t even subscribe, it doesn’t do what it says it will do!!!!!!.Version: 1.2.18

Not sure it’s working properlyBought the app specifically for oxygen levels. Heart rate works very well. Thought oxygen section was working so upgraded and it still doesn’t work. You have to put your oxygen level percentage in the app but I don’t know it as doesn’t provide this info. Help please!.Version: 1.2.2

How do I cancel.I can’t find a way to cancel this app. I don’t want even the free week.Version: 1.2.10

False advertisingDoesn’t work connected to a watch no matter how new the watch is.Version: 2.13.0

RubbishJust got an Apple Watch and wanted to know my blood oxygen levels that were supposed to be measured via my watch. Apple told me to download the app to do this. Can’t do it from my Apple Watch, no shown measure on the app and they are demanding I enter into a subscription to get the App watch functionality. Not impressed as surely if they’ve partnered with Apple then the service ought to be free?.Version: 2.0.2

No measuring of Oxygen levelsThis app is misleading - only takes your heart rate, not your blood oxygen levels. The upgraded version still doesn’t do it... They imply it does it, but you have to add it manually or have an Apple Watch etc, which isn’t clearly stated..Version: 1.2.3

So dissatisfiedI feel so ripped off paying $19 for premium! I would give 0 stars if it allowed. This app does nothing but track numbers you get from other sources. I could already do this for free just manually putting the numbers from my PulseOximeter into the health app. I only paid for premium thinking it actually did something other then just pull money out of my bank account..Version: 1.2.10

Family members feature is uselessI downloaded as a way to share Apple Health data among family members but looks like that feature is only adding a name and picture for a family member, no data sync..Version: 1.2.11

Confused/MisleadingI have checked and I have the most up to date versions of this app on both my phone and my watch. That being said, this app consistently measures heart rate very nicely, however, there is no consistent measurement for o2 saturation. In order to measure my o2, I need to stop and manually take the measurement. I’m looking for something that is consistently measuring my oxygen saturation as I engage in different activities throughout the day..Version: 1.2.10

Didn’t work / scamInstalled to use with my Apple Watch to measure blood oxygen, it seems to just be a wizard that asks you some questions?.Version: 2.14.0

I would like to give more but…Everything downloaded, iPhone and watch synced, and I can’t get it to measure with my watch. It’s a new version just purchased in Dec 2021. It keeps coming up on the face of the watch saying “0pen Apples “Blood oxygen app and tap start”, but I’m in the actual app and it won’t progress from the screen. So the loss of stars and I wanted to give less is the frustration of getting it going and app on iPhone is so simple with no help mode. Grrrrr..Version: 1.2.23

Does not measure or record SP02 levels .Only measures heart rate . Not pleased with this app ..Version: 1.2.4

Doesn’t measure oxygen levelsGot it to measure oxygen levels as it says it does but it doesn’t.Version: 1.2.2

Daylight robberyIt doesn’t record oxygen levels..Version: 1.2.23

Sp02Specifically purchased for the oxygen thing Itdon’t work useless.Version: 1.2.15

Sneaky name, not AppleSneaky name makes you think it’s the Apple app that’s actually already installed. You don’t need this app.Version: 1.2.23

Absolute crapSays my heart rate was over 90 … have my I watch on and checked my pulse ok’d fashioned and know for a fact my he is 73. This app is ridiculous!.Version: 2.14.0

Junk app unless you subscribeIt claims you can use it with an account or sub, but it only supports a smartwatch with a sub, otherwise you only get a quiz or you have to enter manually reading of o2. It will do pulse but that’s it. If you are looking for a non subscription app for basic O2 checks, this is not it..Version: 2.2.0

Spo2 doesn’t workI got this specifically for blood oxygen monitoring and that’s exactly what it does not do….. what a waste of money and I don’t know where to cancel my subscription.Version: 1.2.11

Can’t measure O2Does not provide button to measure your o2 reading which is why I downloaded this app in the first place..Version: 1.2.1

It doesn’t measure blood oxygen levelsThere is only measuring of heart rate unfortunately..Version: 1.2.23

Does NOT! Check blood oxygen levels!Every review the developers reply “it can check oxygen. Make sure you have the newest version. The app does check levels. Make sure app is updated..“ The app does NOT check your oxygen levels. There is nowhere for it to check your oxygen levels. There are No icons or buttons to click on to check your oxygen levels. There is a place to type in your own oxygen numbers (if there was an oxymeter) but there’s NOT, NO way for the iPhone to measure blood oxygen, NO way. There are NO options, NO Screens, NOTHING that says check oxygen here, IS NO WAY this app does NOT do it! You do say in description you need Apple Watch or meter to get notifications but, it doesn’t say you need the watch or meter to take your blood oxygen. From a brand new iPhone 12 Pro Max user..Version: 1.2.14

This seems like a conI have a smart watch.. synced to the app… still only offers me the opportunity to manually enter… what’s the use of that? Don’t advertise things you can’t do. Good job it’s a free trial… If it doesn’t give me an oxygen reading by tomorrow it’ll be deleted and forgotten… and In case you’re counting on me forgetting to cancel my subscription I’d like to reassure you there is no chance of that. This is only a heart rate monitor… therefore a waste of all our time!.Version: 1.2.11

FakeHooked it to my Apple Watch. It doesn’t measure oxigen levels it just give you a questionnaire. Very deceiving. Do not buy!.Version: 2.5.0

Nifty but sneakyGood UI but sneaky to cancel subscription. Upon installation you set it up and the very next step is to force subscription with cancel blurred out. I deleted the app immediately..Version: 1.2.2

The APP title is just so misleadingThis is NOT a blood oxygen monitor at all. Yes you can monitor your heart rate but you can get this free on Apple. What a waste of an annual subscription! Am SO disappointed. All this does is allow you to track your oxygen levels that you take yourself on an oximeter. Please can I have my money back..Version: 2.28.0

Log is useful but…The blood oxygen app is supposed to send alerts for low blood oxygen. I cannot get that part to work at all. The logs that it keeps are useful. But because of a history of pulmonary blood clots, I need to know if my blood oxygen level is falling. I cannot figure out how to set up that notification alert..Version: 2.13.0

SxWaste of money Can’t get blood oxygen level.Version: 1.2.12

GarbageDoesn’t scan oxy only does heart rate .... scam!!.Version: 1.2.5

Latest update is faultyThe latest update is faulty. It requires you to take a heart reading and populates the reading however then asks for oxygen level without taking a reading It’s an app that doesn’t work.Version: 1.2.11

Start buttonI can’t get a start button to appear so can’t take measurements from my watch which was the whole point..Version: 2.4.0

RubbishCost a lot and nothing like I thought it would be.Version: 2.3.0

Broken since updateBlood oxygen monitor stopped working. I can now only use heart monitor which was not what I paid a years subscription for. I want my money back.Version: 1.2.11

Not an oxygen testJust a survey, no o2 test whatsoever.Version: 2.1.0

Deceptive cu*tsClassic bait and switch. I don’t want to pay a subscription to a dubious “service” that cost more than an actual medical oximeter device. User beware!.Version: 1.2.23

Does not use the watch for oxygen levelsThis only asks questions and takes your blood pressure to get an Oxygen level. Apple advertised to use this app and a Apple Watch to read your Oxygen level. The watch doesn’t do anything and the level is based on how you answered the question. This a complete HOAX! Telling people to by the watch and pay for the app is a waste of money. I have sleep apnea and thought this could be used as an oxygen sensor, but this doesn’t monitor anything..Version: 2.22.0

You can only monitor your heart rateI subscribed to this app just because I wanted to monitors my oxygen level from the app itself and you can’t it just monitor heart rate well my Apple Watch and many apps can do that free of charge..Version: 1.2.22

AwfulBlood oxygen measurement is hidden behind a subscription paywall so there’s no way to know if the app is any good - so I’m just going to assume that the app is just awful and that it should be avoided at all costs..Version: 2.13.0

Refund pleaseWaste of money doesn’t work. I have latest devices with updates and it doesn’t work.Version: 1.2.23

This is not as described.It doesn’t measure your blood oxygen levels.Version: 2.13.0

Borderline conThis app is a con, and should be removed from the App Store. Firstly, it’s name is designed to confuse - it is not apple’s ‘blood oxygen’ app for the Apple Watch which has to be accessed directly through the App Store on your Apple Watch. Naming this app ‘blood oxygen app’ when there is an official ‘blood oxygen’ app is almost a scam. I am shocked it was approved. Why would anyone need a specific app to ‘record’ blood oxygen levels. I suspect most, like me were actually trying to measure their blood oxygen levels. I have been scammed out of a subscription fee and a lot of trying thinking. I hope I can help others avoid being conned. For apple watch users who want a very helpful blood oxygen app download the free apple app directly from the App Store on your watch. I’d appreciate any tips on how to get my subs back..Version: 2.12.0

Measure Heart Rate OnlyThis app does measure only heart rate, nothing else. I have Iphone X and Apple watch series 6, and tried everything to measure oxygen blood level with this app and nothing worked. I sent the questions to the developer, but no response; very disappointed. However, you can use other equipment to measure it, and log it in manually. I don’t need this app for that. I’m uninstalling the app; sorry doesn’t work for me!.Version: 1.2.19

Doesn’t workSimply doesn’t work. You can Wait and wait and wait for a reading. Then give up..Version: 2.0.0

Not as advertisedMy comments echo others in that there is no oxygen measurement available. The app is advertised as an oxygen measuring app. It’s not. AVOID..Version: 1.2.2

Pulse ox failDownloaded specifically for the 02 sats part but app will only give option to monitor heart rate. 🤷‍♀️.Version: 1.2

Why?This is presented as a means of tracking your heart rate and blood oxygen to your Health app by use of your camera on your iPhone or your Apple Watch. The Apple Watch already tracks your heart rate. If the best test for your blood oxygen rate is figured by holding your breath for a certain amount of time, why are you paying $20 a year for tracking how long you can hold your breath?? If you could provide Blood Pressure and feed that data to the Health app on a regular basis, maybe, but not this. No , thank you..Version: 1.2.10

Stupid garbageI don’t have time for this subscription scam/trap.Version: 2.24.0

DisappointedI was so excited to find this app because it was exactly what I was looking for. My oxygen drops at random times requiring the need for oxygen. Being notified of the need for oxygen seemed like a dream come true. Unfortunately this app doesn’t deliver results consistent enough to trust. I still need to review this information on the My Health app. I reached out to the designer with no response. Disappointing..Version: 2.18.0

Heart rate onlyGot this to measure oxygen levels but can only do heart rate. You have to manually enter the % yourself; I thought this app would work that out for me..Version: 1.2.2

Confusing description..I was expecting blood oxygen readings to be tracked from my Apple Watch, but the app only accepts manual readings from a separate Oximeter. So this app isn’t necessary at all. Misleading and confusing. Disappointed user!.Version: 2.24.0

Heart rate onlyI’ve downloaded app and won’t measure my oxygen. Just heart rate.Version: 1.2.1

No oxigen level measuredOxigen level is not measured. It looks like a cheat even after buying the premium subscription..Version: 1.2.10

Miss leadingIt doesn’t measure you blood oxygen it just has a log for you to input the result..Version: 1.2.20

UselessTerribly difficult to work. Not worth the free trial..Version: 1.2.23

Waste of time and memory of your phoneIt has a photo that which is misleading. It shows that you can put your finger on the back camera-flash to monitor your heartbeat, but in reality it doeasnt work. You need another device to track your heartbeat and blood oxygen. If I have another device to monitor my heartbeat and blood oxygen, why do I need this app? Waste of time, money and also phone memory..Version: 2.6.0

Watch App Is A Premium FeatureDownloaded the app expecting it to be like any other app that supports apple watch- free, but was really disappointed to find out that it’s a premium feature, it will download to your apple watch, but won’t open without saying it’s a premium feature. Isn’t mentioned anywhere in the app description, or else I wouldn’t have downloaded it..Version: 1.2.10

Oxygen levelsMy all will only measure heart rate and not the blood oxygen levels which is what I really need it for!.Version: 1.2.1

Cannot track blood oxygenDoes not specify that if you do not have an Apple Watch 6 or 7 that you cannot track blood oxygen. Instead you have to enter it yourself which you cannot figure out unless you had another device already tracking it. Paid £22 that I now can’t get back. What a waste.Version: 1.2.23

DisingenuousAsks you to download the app then says it’s a premium app and costs money. Try to be honest from the outset and maybe more people may purchase the app.Version: 1.2.14

Not accurateI suspect it’s the watch, not the app, that is consistently giving me incorrect readings when compared to the one I use in my finger, like doctors use. My results on this app are consistently 8-10 units lower than the device I’ve used for years. I have cancelled my subscription, but really would appreciate at least a partial refund, I can’t depend this at all..Version: 2.21.0

No oxygen saturation measuredThis app does not measure blood oxygen levels..Version: 1.2.1

Does not do as saidDownloaded app and measure Heart rate - my watch does that no need for app. I wanted to measure oxygen levels as stated but it does not do that as you get prompted to enter oxygen in % - review title as misleading.Version: 1.2.2

Literally a scamI paid for the app, don’t trust them when they say update the app. Nothing will work..Version: 1.2.23

HR Oximiter appApp gives HR but not Ox. Previous reviewer was told to update???? How?.Version: 1.2.15

Not workingDefinetely not measure anything! Just you can record datas from somewhere else. Really dissapointed..Version: 2.10.0

OxygenIt does not measure my oxygen flow.Version: 1.2.11

Complete scamGarbage app. Got it to try and measure my O2 levels via my apple watch and all it does is ask me a questionair. Not only that but they charge you $25. Total scam..Version: 2.13.0

This app doesn’t workIt does nothing. I already have heart data on my Apple Watch. Can you assist in cancelling this purchase immediately..Version: 1.2.23

Misleading you need a series 6 + watchFelt they deliberately not tell and just say you need an Apple Watch. Wasted $28.99 for a useless app..Version: 2.5.0

Does not monitor O2.This app does NOT give you a reading. It simply allows you to input a reading you get from a different device so you can track it. Save your money, it’s useless. Scam app..Version: 2.12.0

Doesn’t do what it’s supposed toSimply doesn’t measure blood oxygen levels Avoid.Version: 2.12.0

Is hard to figure outI bought this app figuring there was a way to take your blood oxygen levels on the app with my phone. I can’t figure it out if it is possible there are no instructions and from what I can figure out it just keeps track of the levels taken another way. This was not what I wanted. I also want to quit the app during the trial period and can’t find out how to do this Am not impressed.Version: 1.2.23

Deeply unsatisfied with this app. Misleading advertisingI downloaded the app as it was in the health checklist under the tips app on my iPhone. I thought it would be good for my asthma but then It wouldn’t let me proceed with the app off my Apple Watch without subscribing to it on my phone… even though it said you can get a free trial. It then charged me straight away and I cancelled the subscription not long after as on the Apple Watch it did not count my oxygen levels. It only tracks the heart rate which is already calculated on the free heart app on an Apple Watch..Version: 1.2.16

FraudOffered at around £ 8.49 charged twice that.Version: 1.2.21

FraustratedI am extremely fraustrated with this app as I have wasted time and effort as it does NOT measure SPO2 as described , I started off with the 9.99 and then upgraded and still NO SPO2 , Apple why do you allow misleading apps . I do not own an apple watch only a iphone 12 . There is no mention that you need a watch in the description , absolute fraud.Version: 1.2.16

Doesn’t do what it saysPaid for the weekly subscription and it still won’t let me measure my oxygen levels what a scam.Version: 1.2.12

Scam7 days free then requires payment. Deleted the app, I idea if I’ll be charged. “Pulse oximeter” has nothing to do with your pulse or metering. It asks you to hold your breath and guesses what your level is. That’s it. Complete crap..Version: 1.2.10

Can't connect to app supportThe App Support link takes you to an option to download a new app. I want app support; I don't want to buy something else. I would like to know how to cancel the heart rate tracker. I already have one. I just want to track my blood oxygen level. And I want to know if this is possible BEFORE confirming my subscription today but the app has decided to take my money already! Not nice. Can someone answer my question before I fight the charge?.Version: 1.2.23

Details for cancellation of subscriptionThis App does not do all it claims to do. We all want the Oximeter readings because of the Covid-19 pandemic. This is false advertising! Please publish details of cancelling subscriptions..Version: 1.2.3

How do I cancel?Hi, I wish to cancel this free trial. If I remove the app does it stop the payment in a week?.Version: 2.13.0

It doesn't measure blood oxygen level. Just heart rate.I can't understand why the Apple store still lets this app with this title be in the list! It doesn't measure blood oxygen level. Just heart rate..Version: 1.2.3

Utter rubbishI’ve installed it, done everything I possibly can on my watch and phone but IT DOES NOT WORK!! Stop telling people to update the app. I’ve got the current app, it does not work! Give proper clear instructions..Version: 1.2.18

Low O2 alert was not triggeredI got this app specifically so I could get an alert when my Apple Watch detected a low O2 level in my sleep. It didn’t raise an alert and now I feel that I wasted my money for a yearly subscription.Version: 2.5.0

I paid for a full year and the app crashedI just. I don’t want to have to buy the full year again because the app crashed. I did click “restore purchase” and the app took 30 minutes just loading the screen and I’m not sure what to do. I can’t even contact customer care about it so I can at least either get a refund or at least get the year subscription. I’d suggest maybe using a different app or at least contacting someone to help make the purchase im not sure.Version: 2.21.0

Inaccurate information DON’T WASTE YOUR MONEY!I already deleted it. Prior to obtaining an SpO2, the app requires that you answer a series of questions about your health. You can either answer yes or no to these questions. Excited to try something new, I pressed all no’s for the first series of questions. And the result was, “normal level. Your red blood cells are well oxygenated. In the next second I redid all the questions with yeses. The result was “Extremely low level. It seems that your blood oxygen level is dangerously low. “ Next I checked my SPO2 on a finger pulse oximeter, I bought during Covid The result was an SPO2 of 96% which is great with or without disease..Version: 2.9.0

MisleadingIt does not read your blood oxygen, just gives you a place to record readings from a separate device.Version: 2.15.0

OkIt’s good when it works. Most times lately your lucky if it will upload the O2 ratings for that day let alone that moment. It’s extremely inconsistent almost to the point of uselessness.Version: 2.21.0

App doesn’t work with my Apple WatchApparently it does not works with version 5. I have just paid for a year. So feel very cheated that this was not made very clear when buying the App. I think you should make it much clearer what versions of Apple Watch it works with as it isn’t obvious from the App store.Version: 1.2.21

Fake appDoes not measure blood oxygen even though it’s called blood oxygen app. You can manually enter your blood oxygen from a separate device but why would you download a blood oxygen app that doesn’t measure spo2?.Version: 1.2.2

False AdvertisingAbsolute rip off. You have to have a gadget or device to measure sp02 this it is expensive and other apps that are free are far more useful.Version: 1.2.20

Fake appWhen I cover the flash and camera with my finger, when I lay my phone on the bed or if I hold my phone in the air it still says 95-99% O2 saturation. I’m highly disappointed.Version: 1.2.10

What a jokeFirst off this is a scam! Nobody will get back with you,no contact number just fake email,I have a Apple Watch SE and when I ordered subscription,they took my money instantly,then conveniently it came across screen saying your watch does not support oxygen level,I canceled subscription immediately within 10 minutes,no refund,makes absolutely no sense why this app has a 4.6 rating,read all the bad reviews and it’s almost everyone who has nothing good to say,not once will you see in reply from developer offering money back,I’m going to contact the App Store and report them.Version: 2.21.0

MehDownloaded to measure O2 and the tool is just a questionnaire, not a measurement.Version: 2.3.0

Please fixI downloaded this app to see my blood oxygen on my Apple Watch and the Apple Watch mode is premium and you have to pay $25 a year. Please make this free to see on Apple Watch..Version: 1.2.10

Apple Watch app sends me in a loop to my phoneI bought a brand new Apple Watch series 7 but had previously purchased this app prior to buying the watch. Something is amiss in the watch/Apple Health phone connection because the when I try to measure my oxygen levels on my watch, it sends me to the phone app which never displays the start button. I’ve updated everything, reinstalled multiple times to no avail. It appears that the issue is due to me setting up this app prior to having the series 7 watch. I’m at a loss and very frustrated as this is one of the main reasons I bought the watch. Help!.Version: 1.2.23

It is called Blood Oxygen AppIt is called Blood Oxygen App and it tells you to type in your oxygen levels does not read them. That’s the whole reason I bought this app. Not happy.Version: 1.2.23

Doesn’t measure 02App just asks questions about your physical condition at the moment and then tells you if it thinks you’re “a-okay” 🙁 doesn’t actually measure and give you real-time oxygen level..Version: 2.1.0

Oxygen levelThe oxygen level doesn’t work can’t use it.Version: 1.2.2

Parts of this aren’t accessible users, who are blind, or visually impairedHello, I am a user, who is totally blind with light perception only. Since I cannot exactly see the light from the camera, however, I do not know where the front facing camera is actually located on my iPhone. There is no tactile marker for that, or the flash, so I cannot accurately use send features to track heart rate. However, my much older Apple Watch is too can’t work with your app either. I will do the best I can, but have no other pulse oximetry data in the form of devices that can load with this app. Very good, voiceover support, by the way. Very good day..Version: 2.15.0

Deceptive subscription process & poor performanceI signed up for a week at $4.99 and was billed over $30.00. Have complained with Apple seeking a refund. Don’t waste your time or money..Version: 2.15.0

Won’t read my o2satIt will let me manually type in an o2sat, but it won’t measure it on my Apple Watch. It doesn’t make sense to log in a value I don’t even know..Version: 1.2.14

It’s a Heart rate app not a blood oxygen appThis app does not tell you your blood oxygen level . I downloaded this app for that reason and all it does is tell you your heart rate . It manually wants me to input my blood oxygen level ... I obviously don’t know what it is , I downloaded this app for it to tell me . I have no Apple Watch or other device I’m simply using my iPhone 8 to use this app and it’s only good for your heart rate . I wanted to know my blood oxygen level for my asthma.Version: 1.2.3

Ridiculous and dangerousIt has no ability to check blood oxygen. I have Covid and I don’t have a pulse ox yet. I downloaded this out of curiosity. I hit the button to say that I don’t have a pulse ox device, it asked me some questions, then told me my blood oxygen is fine. This app should be reported and removed from the App Store for giving people false readings related to their health. If someone genuinely was in physical distress and trusted the false advertising of this app, they could be in real danger. A lot of the reviews are clearly fake as well, which implies that they’ve paid for reviews. Their thermometer app is the same. It’s sick to put people at risk just to make a few bucks. The developer should be prosecuted..Version: 2.9.0

Not a scientific basis for measuring blood oxygenI downloaded this app to see if it. An really measure blood oxygen. It asked me to hold my breath for a certain duration and then gave me an indicative range of O2 saturation. I do not believe this is particularly reliable and ended up purchasing a proper oximeter. To make matters worse Apple charged me 29.93 Canadian Dollars for a 1 year subscription that I am challenging. This is a complete waste in my personal opinion..Version: 1.2.10

Doesn’t WorkI do not know how this app gets so many positive reviews. It does not work accurately it consistently says my blood oxygen is in the high 80s or low 90s; I would need to be supplemented with oxygen if this is the case, which I am not. When I put a pulse ox on my finger, I am consistently in the high 90s. I signed up for the trial for one week and within three days, this company charge my credit card. I have requested a refund, purchaser beware..Version: 2.8.1

10 Plans! No description of differenceOne plan is $14 a month, another is $20 for the year. There are 10 different plans, no way to tell the difference. If you just use the built in FREE Blood O2 app with the watch it works better and doesn’t cost money. I was hoping this would be a more user friendly way to monitor my child’s O2 it the app failed miserably to offer any benefit beyond Apples built in app..Version: 2.10.0

Not accurateThis app started out well the first few days. Now after a a couple of weeks it only records my stats occasionally. I have serious blood oxygen fluctuations and was hoping to keep a daily diary of the figures. I have contacted them, but to no avail. I will not renew when my subscription is up..Version: 2.14.0

Doesn’t work on phone. Rip off. Money back pleaseI’m an older woman with asthma. I got Covid-19 last week. I purchased the app yesterday, I have an Apple Watch SE, yes, I know that it’s not supported, but it doesn’t work either as stand alone on Apple phone. No where did it reads that the app will not work on phone. Cannot not reach developers for a refund, help! I purchased a year’ subscription. I made purchase yesterday, removed today. Help, help, help, help, help!.Version: 2.13.0

5⭐️ reviews are misleadingIt doesn’t take your oxygen level it just asks you how you’re feeling and estimates based on that. It measures heart rate the same as all the other apps out there. The inflations of 5 star reviews could be because the app asks you “do you like that you can measure heart rate for free?” Of course you’ll say yes. If it asked my opinion I’d say 2 stars max. Misleading about what you get for free.Version: 2.2.0

Do not buyLike other reviewers, I was expecting to put my finger to the camera and get a blood oxygen reading. Instead it asks you to complete a questionnaire and uses an “algorithm” to estimate your blood oxygen level! I feel that I have been conned. At 17 GBP it’s no joke. If you have had the same experience, don’t forget to cancel your subscription..Version: 2.24.0

It’s not workingIt’s not measuring my oxygen level, it asked me to put the amount of my oxygen level manually, but not measuring, I paid $32 +, thanks.Version: 1.2.13

No customer supportI get a message that recipients mailbox is full For a month now when I have been trying to get a hold of this company for customer support.I reviewed a few weeks ago that I don’t get alerts most of the time when I’m sleeping and sleep focus is off, and their response was have you tried to get a hold of customer service. Losers.Version: 1.2.23

Not able to try it out and no access to fee trialI downloaded this as there was an offer for 3 days free before the subscription would kick in. It was not what I was looking for so within an hour of downloading I cancelled the subscription. I also reached out to the developer to advise them this had happened. To my surprise I find myself billed a week later for an app subscription, properly cancelled and then some, that I do not want. I have had to reach out to Apple Pay directly. Extremely disappointed with this type of ‘but before you buy’ app and will not recommend this developer moving forward..Version: 1.2.23

Totally useless appI subscribed to this app and did 2 readings for the 02 saturation level. The results presented were underwhelming “normal”. Whatever does that mean? In reading the description, it shows all kinds of readings in %ages, but why did I not see that. Just to be clear I actually subscribed for it and then cancelled it when I saw no useful information displayed. I wonder if this has anything to do with 7 day trial that I checked when subscribing. If it is, then shame on the app developers who so not have confidence in their app to provide a real experience for a week. I would have kept my subscription if I thought it was useful, but then too bad that the developers don’t trust their own app to keep the users for a week without the click and bait. I usually do not provide negative feedback, but this experience was not what I expected..Version: 2.23.0

ExpensiveCan’t check Oxygen Saturation without paying. Apple needs to stop showing apps as being free when they are just scamming users into subscriptions.Version: 1.2.16

Doesn’t measure oxygen saturationI downloaded this as I thought it would measure blood oxygen - but it doesn’t, it only measures heart rate..Version: 1.2.2

So ConfusingI’d like to hear from the people that gave this good reviews why? Do you have to buy the premium to do anything? I have an Apple Watch SE and my watch won’t let me use it, just says “this is a premium function, check your phone”. When I check the app on my phone there is no instructions on how to measure blood oxygen. I only have the option to add my own number from an outside source, which I set up as my Apple Watch in the beginning when you first open the app. Which is still not working on my Apple Watch. If this app can only track your heart rate for free and not O2 than it is useless because the watch already tracks your HR for free..Version: 2.13.0

No O2 measurementI was under the impression that this app MEASURED my O2, it doesn’t. Now I have to figure out has to cancel my free trial before the week is up..Version: 2.0.0

It’s not a free app!!It will ask you to pay for subscription after 7 day free trial..Version: 1.2.17

Doesn’t measure oxygen levelsDoesn’t actually measure oxygen levels! Just an app to enter it in..Version: 2.0.2

Only picks up pulseYou have to keep reading the description and will find 3 paragraphs down that it does not pick up oxygen levels because the Apple Watch does not have that ability (yet). So you pay $20 to have it record your pulse which already shows up in the Health app. Then you have to check your sat yourself with an oximeter and enter it into the app. I requested a refund but did not hear back..Version: 2.9.0

Terrible user interfaceThis app is ridiculous. Super hard to use. Costs money. After 800$ spent on a watch with embedded o2 sensors it’s super hard to use and apparently costs money for a premium plan. Come on Apple. This should be free like the ECG and pulse. It should be simple to use with one button to get spO2 on the watch. Instead I recommend buying a $10 finger oximeter which is simple and free. Paying $240 a year to Apple for this feature is a complete ripoff. Shame that it’s built in and super hard to use and costs money to access it easily. Change this please Apple..Version: 2.11.0

Subscription cheaper buying a real monitorCould not get past the first screen where it asks for a ridiculous subscription, one months subscription would pay for a nhs tested pulse and oxygen monitor..Version: 2.28.0

Too expensiveToo expensive should be cheaper.Version: 1.2.11
