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.
With this in mind, I looked at the calorie calculations for both the Apple Watch and the Fitbit. On Saturday, the Apple Watch credited me with 687 active calories and 3,180 resting calories, for a total of 3,867. The Fitbit app calculated that I burned 2,742 calories. On Sunday, the Apple Watch counted a total of 3,915 calories, compared to 2,752 for the Fitbit app.
