Frequently asked questions
How are calories burned calculated?
Calories = MET × weight in kg × hours. Each activity has a MET value (running ≈ 9.8, walking ≈ 3.5) that reflects its intensity.
Are these numbers exact?
They're solid estimates. Actual burn varies with fitness, terrain, and effort, so treat the result as a close approximation.
