Perfect and simple

I like the oportunities in app. The accuracy is very high or almost same with comparison of medical equipment. I am recomending to use this app as mobile home equipment.

One of the better ones

One of the better apps of this sort. My only complaint so far is that in free version it automatically marks all heart rate measurements as “at rest” (even though you just finished a number of pull ups in the gym) and then uses these wrongly marked measurements for all sorts of stats comparisons and such.

Looks good

Works fine as I can say.
