Heart Rate Variability Logger

computes non-physiological HRV values (e.g. often rMSSD >800. In one recording even >20.000!!). -> No trust if in the rest of the time, when the values are physiological, they are any accurate ... I do not like to give negative reviews, so I emailed the dev 1 month ago, sending him a screen recording. He did not bother to answer ever since... Looking at his blogs and at his answers to reviews, this app is dead since a year

Works as expected thanks 👍! I'm using it with polar H10 Band to measure longer periods and use data for kubios light version (free). So far measuring it during hours was working fine. Letting app run in the background. I still need to test the whole night. When moving to far away from your mobile phone the connection might interrupt und you can't resume. Just make sure you don't use the time stamps when importing. Then it works perfectly.

Bought this app.. now it simply refuses to pick up my heart rate monitor. every other HRV and heart rate app picks up my chest strap H7 and H10. I wish I had checked the last update date before spending money on this app. please fix the Bluetooth connection issue and let me know. otherwise I will apply for a refund. I have had hardly any use from the app and I need the data.

Stopped working after few days. Now even reinstallation doesn't help

I would give zero stars if I could. Only updates alpha-1 no faster than 30 seconds making finding your LT1 and LT2 impossible. Use web based Runalyze instead.
