HRV4Biofeedback

Love 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

I’ve really benefitted from regular RF breathing and biofeedback using this app. It’s really helped me manage stress much more effectively. I do wish there were a more robust set of external accessories. I often want to practice hands free, so I don’t need to be holding my phone to use the app, and I’m not aware of an external device that both measures your HRV and gives a vibration and quiet sound indicating the breathing intervals.

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.

I doubted their claim of HRV and HR accuracy. I have a Polar h10 and I compared measurements and to my surprise HRV4BIOFEEDBACK optical sensor accuracy was the same as Polar! Very impressive. I like how you get the scores and can see the effects on mood and whatnot. Helpful to see trends over time. Major criticism is that the breathing visual is hard to see. They need to do something with more contrast. Only rated 4 stars because there is so much more they could do with the biofeedback exe

I bought my iPhone SE just to use these apps, and they do not disappoint. Major boost to daily insight into your health, with a reliable way to induce parasympathetic nervous system response and relax into being a healthier person.
