Simple, clean and accurate. I'm using with Polar H10 chest strap and it's on par with other HRV apps I've tried. Only reason for 4 stars is the previously mentioned lack of explanations for the data, and lack of response to my email. A simple FAQ or Wiki would be immensely helpful (especially if it had links to research), but in the meantime I'd really just like to know what stress index this uses. The number is fairly meaningless without understanding what it's measuring and what it means.

I like this app a lot. I'm using it with a Polar H10 chest strap and it works well. The app displays (in real time) the data in which I'm interested - in particular, RMSSD. Kudos to the developer and keep up the good work! For how long does the real-time stress value have to exceed the set limit before sounding the stress alarm? Thanks in advance. 1 Sept. 2022
