FAQ
How do I measure my sweat rate?
Weigh yourself right before your workout and again right after — ideally without clothes and towel-dried. Enter both weights, how much fluid you drank, and how long you trained. SweatRate does the rest.
What's the formula?
Sweat loss = (weight before − weight after) + fluid you drank. Sweat rate = sweat loss ÷ time. It's the body-mass method used by sports scientists.
Do I need special equipment?
Just a bathroom scale. A more precise scale gives more accurate results, but any scale will get you a useful estimate.
Is my data shared?
No. All your records stay on your device. SweatRate has no account and collects no personal data.
What does SweatRate Pro include?
Unlimited session records, the full sweat-rate trend chart, and your rate for every temperature band. It's a one-time purchase — no subscription.
How do I restore my purchase?
Open Settings in the app and tap Restore purchases. Your Pro unlock will be restored on any device signed in with the same Apple ID.
