FAQ
How do I restore my purchase?
Open Settings inside the app and tap "Restore Purchases". As long as you're signed in with the same Apple Account you bought Pro with, everything unlocks again at no charge — including on a new device.
Where is my data stored?
Everything stays only on your device. Nothing is uploaded to any server and no account is needed. If you delete the app, its data is deleted with it.
How is the sweat rate calculated?
Using the proven body-mass method: sweat loss = (weight before − weight after) + fluid you drank, and sweat rate = sweat loss ÷ time.
What's the difference between free and Pro?
The free version covers your first 3 sessions. Pro is a one-off purchase that unlocks unlimited records, full trend charts and temperature insights. There is no subscription.
Do I need an account?
No. There's no sign-up, no login and no ads. All your data stays on your device.
