Just get an arm strap for your phone. you’ll have to manually count your heart rate BPM. But you’ll have the largest screen for a watch.44mm. Need something as big as possible.

The screen on the 40mm is larger than the current 42mm. Hope that helps.That’s a good point that I didn’t consider. I think I’ll start with the 40mm and if it doesn’t work out I’ll get the 44mm.
