Frequently asked questions

How is the burn calculated?
It uses MET values, a standard measure of an activity's intensity, multiplied by your weight and the time. Heavier people and longer or harder sessions burn more.
Why does my tracker show a different number?
Wearables use heart rate and personal data, so their estimate differs. Both are approximations; treat either as a ballpark, not an exact count.
Does body weight change how many calories I burn?
Yes. Moving a heavier body takes more energy, so for the same activity and time a heavier person burns more calories than a lighter one. That is why the tool asks for your weight.
