The Apple Watch uses your age, gender, height and weight, in addition to the GPS in your iPhone and data from its own built-in sensors, to calculate both your resting calories and ones you burn during exercise.
The Activity app also shows you more detail: the number of calories, number of active minutes, workouts (if youâve used the Workout app on the Apple Watch), and the number of steps youâve taken, and their distance. Itâs this final metric that allows one to compare the Apple Watch with other devices.n Sunday, the Apple Watch counted a total of 3,915 calories, compared to 2,752 for the Fitbit app. Iâm not sure how these numbers can be so widely divergent. I tend to think the Fitbit app is more realistic (neither can be accurate, since measuring calories is a bit of black magic).
