Camera Heart Rate Variability for Android

I paid for this and a few months later it just stopped working. I can’t speak to the science behind it but it did work as sold for those months. Low rating is due to how it stopped working and the lack of support to fix. I uninstalled and reinstalled and still not working. Cleaned my camera. Re read directions, googled. Nothing. App developer says we can tweet him, I only use Twitter for work, so. Maybe they will see this and reply? FX.

I have used this twice and now the timer doesn’t start. This is beyond frustrating.

I used this app for the last year and really liked it but in the last month the timer has stopped working so it only tracks number of beats per minute and nothing else. Maybe it needs to be updated to keep up with the Android updates?

The new version is a HUGE improvement in signal acquisition. Works much better and has more consistent analysis. I tested this against a laboratory grade HRV instrument and it was quite close. It would be a good app addition for lay people to state “normal” levels and explain the different features and how they impact health and HRV. Would also be nice to choose which studies to graph together to show trend. This is better than most consumer HRV. If you are serious about measuring you HRV and want it to be easy and accurate, you need this. Very reasonable price too.

Used to love this but now every time I measure on my Android it crashes
