How does your phone work as a fitness tracker with HRM ?

If you actually want good heart rate monitoring you get one of those straps that go around your chest anyhow.

I have that too, nothing beats the convenience of the watch for daily runs / hikes / lifting.

Anyway you need something to record the data from the chest strap, again the watch is best for this. Running with the phone sucks.

That’s a pretty bold assumption to make.
