Activity tracking - smart enough not to double count calories?

[alFR]

If you go for a run with your watch and use the workout app to track it, the watch will presumably also count your steps with the accelerometer. Is it smart enough to not add both the calories it would count from those steps if you weren't doing a workout as well as the calories calculated from the workout into your daily active calorie total in HealthKit? I'm specifically thinking of if you use it with another app like MyFitnessPal, will it double count the calories from the period you're running?

Nope, doesn't double count.

Nope, doesn't double count.

Thanks, thought it probably wouldn't but good to have it confirmed.
