In regards to BIO 2
Maybe an option to leave screen on all the time you can toggle off and on. I say this only so I can see heart which is continuous. It defeats the purpose of continuous heart rate if I have to tap the screen every 2 seconds 2 check. While walking fast or jogging it would be nice to see constant heart rate without stopping every 2 seconds to tap the screen to make it come on and see the HR.
Sorry I meant to put this in requests but did not see that option.
