The gym accountability app with real money on the line.
Join a paid weekly workout challenge hosted by your favorite fitness creator. GPS-verified check-ins. Weekly Stripe payouts. Upside when others miss.

Accountability that actually works — because the stakes are real.
Real money, real stakes
Stake $20/week. Hit your weekly gym target, get your stake back plus a cut of the forfeit pool. Miss, your stake goes to the completers.
Gym-verified check-ins
GPS geofence of your registered gym, plus an on-device session timer and optional photo. No honor-system fudging.
Hosted by creators you trust
Every challenge is run by a fitness creator — your favorite coach, your favorite program, your people. Group workouts, collab photos, leaderboards.
Specific numbers. No vague claims.
