Frequently Asked Questions

How many calories does running burn?

Burn = MET × weight × hours with running fixed at 9.8 METs: defaults (running, 70 kg, 30 min) give 343 kcal. Weight and intensity swing totals ±30%, so treat them as planning fuel, not lab truth.

Which activity burns most?

Running and vigorous cycling top the per-minute list; walking and yoga trail at a third. Duration beats intensity for totals — 60 easy minutes out-burns 20 hard ones.

Can I log this for diet planning?

Yes as estimates: eat back at most half of exercise calories when losing weight, since trackers overestimate. Pair with a food scale for real deficits.

Is my data uploaded?

No — estimates compute locally in your browser. Nothing leaves your device.
