Frequently asked questions

How is the calorie burn calculated?
It uses MET (metabolic equivalent of task) values assigned to each activity, combined with your body weight and duration, following the standard formula used by fitness trackers.
Does it account for exercise intensity?
Many activities offer light, moderate, or vigorous intensity options, since effort level significantly changes calories burned for the same activity.
Is it free to use?
Yes, completely free.
Is my data private?
Yes, the calculation happens locally in your browser โ€” nothing you enter is uploaded or stored.
Is the estimate exact?
No, it's an estimate โ€” actual calorie burn varies by individual metabolism, fitness level, and exact effort, so treat it as a reasonable approximation.
