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.
âIn addition, the more you run with the Workout app , the more Apple Watch learns your fitness levelâand the more accurately it can estimate the calories youâve burned during aerobic activity,â Apple notes. Also referred to as Resting Metabolic Rate (RMR), resting calories differ from one person to another.
