Prove it with the workout you already recorded

How does verification work?

• Pick the challenge, for example Run 100km or the Century Ride.
• Tap "Verify from a recorded activity". GritCore lists the workouts that could qualify.
• Choose one. Distance, duration and climbing are checked against the challenge automatically. Nothing is typed, so nothing can be mistyped.
• Done. The claim is marked verified and your rarity updates.

Which apps and devices work?

Anything that writes workouts to Health Connect on Android or Apple Health on iPhone: the phone's own tracking, most smartwatches and most running and cycling apps that sync their workouts there. If your watch appears in Health Connect or Apple Health, GritCore can read it.

What about strength challenges?

Reps and holds (pull-ups, push-ups, planks, wall sits, dead hangs) are not recorded by any sensor, so these are claimed on your honour, with an optional link to a video or post as proof. People who were there can vouch for you; once enough of them do, the claim shows as witnessed.

What does GritCore read, and what does it never read?

• Reads: the type, time, duration, distance and climbing of the workout you choose.
• Only when you ask: when you verify a claim or sync a duel. Never in the background.
• Never: your route, heart rate, weight, sleep or anything else in your health data. GritCore never writes to it either.
