i do, but only becuase i like a quick and easy way to time my rest in between sets in the gym

i quite like it for pulse monitoring as well as i can see my pulse increase by 10 bps when i have a cold coming.

it has sleep tracking but i only use that as a very rough measure to know how many hours i got, i don't want to get weird and obsessive about it

it's handy , i also use the timer on it if i have a nap for example
