Having Issues?

If you are having issues with Heart Rate Graph, you should be patient and read through everything again. It has worked perfectly for me for years now. I use it daily. I am 77 years old. I go to the gym everyday. I do high intensity interval training. I also graph my sleep every night. This app is simple but thorough. The small one time fee allows me to alarm alert me to high heart rate during the day or night due to a medical condition I have.
The app does not have annoying links and suggestions to junk.
This app is simply the best.

Thank you for taking the time to leave such a detailed review - it really helps us to better understand exactly how people use the app and the features they value.

Very good

I use this app to collect Coros HR data which I load to my Oura ring app. Works very well. Only thing missing for me is the ability to delete warm down data when I forget to stop the recording.
