Brilliantly simple

I’ve been searching for an HRV app like this for a long time with no success. This is exactly what I was looking for. All I wanted to do was to use my Polar H10 heart rate strap to measure my HRV and HR while I am sleeping. I don’t want any pep talks or recovery scores or anything like that, just the data — average HR, average HRV, average RMSSD. This is perfect! Thank you so much to the developer for creating this app. I’m not able to contact the developer here but my question is, I assume the HRV metric shown above RMSSD is SDNN?

Raw RR interval export

This is the only app I have found that can export the RR interval data and can be imported to Kubios. I also like that I can run it for any length of time, but would be nice to set another time other than a minute.

iPhones don’t support email of results?

Very confusing. Can’t get detailed results emailed and can’t change length of time of analysis. Kind of useless. Disappointed ☹️
