I bought a VÍVOSMART 4 Smart Activity Tracker with Pulse Ox to perform exactly one function for me: Display My Heart Rate during moderate exercise.
Just want to see my pulse. Accurately. Continuously displayed on my wrist. While I'm on a treadmill, stationary bike, or recumbent climber.
Doesn't seem like a lot to ask for, but I'm finding that it's unobtanium.
Should I just cut my losses at the almost-a-full-tank-of-fuel level and regift this thing, come Christmas time?
Or is there some hope that I can get this basic function to work reliably?
Any feedback -- good or bad -- is welcome, y'all.
