Hi

I want check something cos I am not too sure and can’t find info online to confirm or whatever.

As far I know if heart rate monitor is on and use workout app on Apple Watch and it will continually monitor your heart.

What I don’t know is if I use iPhone app to exercise for example HIIT (wearing watch doing exercise) will Apple Watch continually monitor heart rate or not?

I am new to Apple Watch and learning how use it and understand how it works.

Thanks.

Reason I am asking cos heart rate monitor can use up lot of battery and if your type do lot of exercise say switch off during workouts. I wasn’t too sure what happen if using iPhone exercise app instead of Apple watch workout app.

It will do what it always does, monitor your heart rate at a normal rate because it doesn’t know you’re exercising.
