I don’t recall yet finding a phone-watch with a reliable pulse sensor. That may be because it’s a feature I wasn’t looking for, but it’s also possible that such a product doesn’t yet exist.
You can probably just use one of the fitness bracelets (Fitbit style) and sync them to your phone. I don’t know how reliable they are, but one of their explicit purposes is recording your heart rate during exercise.
Losing the heart rate connection for a few seconds during exercising isn’t a big deal.
The old tech with chest straps certainly loses signals from time to time.
I’m not sure about the newer tech, but I would doubt that you get cheap tech that doesn’t from time to time loses track of the pulse.
