Since Alta HR has no button on it but has the HR sensor, so I'm thinking in the future we can manually start an activity (yoga, workout) from the app, just like how we start an outdoor running right now (if running able to that, I don't see any reason why we cannot do that for other kinds of activity), then it automatic calculate the calories based on the heart rate during the period, so that I don't have to go back to the app to manually enter the time & calories for the activity.
It would be super helpful to me.
