HRV4Biofeedback for Negative User Reviews

✓ Without a separate sensor it’s uselessI got this to see if I could avoid spending the money on a more expensive device. Conclusion is I cannot; using the camera as a sensor (at least on my iPhone SE) is a fool’s errand, it shuts off after ten seconds due to inability to consistently detect. I haven’t been able to use the app at all. Waste of money for me..Alexster0192Version: 1.2.1

✓ “Registration Failed [-1001]”Any one else get this? It’s what I got when setting up the app. Registering an email and a password appears to be required. I don’t have a Twitter account, so no contacting dear developer that way. Did send an email to address listed in app. —— Update: Deleted and reinstalled app. That seemed to work..MosdakVersion: 1.2.3

✓ Still beta qualityI love the amount of detailed science this developer provides on their website but this app isn't usable and it is mostly a documentation problem. 1. The lower limit on breathing rate is stupid and immediately meant the pace was too fast for me. 2. Nowhere is the circle explained. 3. It isn't biofeedback unless there is something that's feedback for me. Just following the pacer is guided meditation at most. I hate to say it but stop trying to explain (or defend) the science and tell the user what they should do. If you aren't certain what that means then you need to spend more on UX No response from the developers after two weeks and there's a bug where it starts showing the pulse as being in the 30s even when it clearly isn't and there is a strong signal.Demihemi06089Version: 1.0

✓ Not really biofeedbackLike an another reviewer said, it’s not really biofeedback if... there’s no feedback. Having a real time HRV number on the screen would bring this to 5 five stars for me..User2836104Version: 1.2.3

✓ Mostly love it but lots of lost dataLove this app and what it does but data only syncs and saves for me about half the time. Possibly it’s just a hazard of rural internet but disappointing nonetheless.Skknut1Version: 1.3.5

✓ Useful but can improveLoved hrv4training so tried this also and because the developers are expert in this field. App uses a dark to light screen change that you follow to pace breathing. The dark/light lighting is not markedly different and difficult to follow. Would suggest greater dark/light difference or a bold white line or circle like “ibreathe”. Would also be very useful to have a sound or chime cue so one could close eyes during the practice and still maintain breathing pace. It would be useful to see the HRV numbers that underly the buofeedback score. I think app will become more useful with subsequent iterations and updates..XLT10Version: 1.0

✓ Update killed it?Maybe HRV4BioFeedback is not working with iOs 16.3? Camera flash turns on, stays on, and no measurements take place at all, screens lock up..SquatasticVersion: 1.3.5

HRV4Biofeedback works most of the time. If it is not working for you, we recommend you excersise some patience and retry later or contact HRV4Biofeedback.
