HRV Monitor for Android
Used on xperia and zte phones. Both come up with error and will not display graph. Says not long enough even though it is. Definitely 5 stars if errors are fixed
No?Not detecting Garmin HRM
My other apps connect fine to my BT HR monitor.
Obviously requires Android >4.3 for BLE, but on these devices this has to be the best Alpha-version product ever written. It includes the FFT to get spectral power for frequency domain recording!
I'm finding a really high potential to love this one, compared to so, so many other apps I have tried for HRV, that are pre, pre, pre, pre alpha testing. It has all the functionality the others claim, but it works. Poincare plot, time domain, freq domain,... BUG: Files in the archive (in English: files) do not display graphs in the time or freq domains. In time domain, an error given is not enough data, but I don't buy that. There is 5 minutes of data for 3 tests I've performed, and the data are graphed realtime, so this is a bug that needs fixed. BUG2: The German-to-English translator needs to be fired :) But, I don't care about spelling errors throughout the menus. Importantly, Everything is labeled!!! (inexusably rare today) It's interesting to watch the axis auto-scaling. It looks noisy at first, but works like a champ. Also, it would be nice if the files were autonamed, since entering a filename is not mandatory for taking data. 3 stars now, 4 if they fix the graphing of archive files. 5 with just a little more polish above that.

Interesting app but it exits without saving data at the end of the timer
