User Reviews and Ratings
★★☆☆☆Not really biofeedback
Like 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.
★★★★★Excellent app, but could use some updates
This has all that I need for using biofeedback to try to improve my training. It is basic but excellent value.
One improvement I'd like to see is better login handling. I've been randomly logged out recently for some reason, and it's a bit of a hassle to log back in. I would also like to see integration with password managers to make this process smoother.
★★★☆☆Mostly love it but lots of lost data
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
★★★★☆Good app. Could use some improvements.
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.
★★★☆☆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.
