Calories (or kcal) is a measure of the energy you've burned during your activity. Our algorithm didn't include BMR (basal metabolic rate). You may notice differences between our calculations and those from other tools, even given the same activity data. This is most likely due to differences in Calorie calculation algorithms, and the data factored into the calculations. We believe our estimation is as accurate as possible given the limitations in data.
