Make a promise. Stake real money. Bring friends along for the ride — or challenge them to do it with you.
How it works
Real skin in the game. Real social stakes. Real results.
"I promise to run 3x this week." Pick your goal, set a deadline, and invite friends to watch — or challenge them to do it with you.
Stake $2 / $5 / $10 / $20+. Keep it -> full refund. Break it -> your friends split the pot, minus our 15% platform fee.
Prove it every day with texts, photos, or screenshots -- step counts, screen time, timers. Build streaks. Watch your progress live.
Friends react with emoji, GIFs, and comments. Nudge each other. Compete on the weekly leaderboard. Earn badges: 7-Day Streak, Iron Will, High Roller.
Built for accountability
For gym goers, students, side hustlers, couples, and anyone tired of letting themselves off the hook.
Your friends see everything — the stakes, the progress, the evidence. That's the point.
Early users
Real stakes. Real accountability. Real change.
"I've tried every habit app. Promise is the first one where I actually don't want to fail -- because my friends will literally win my money."
"My friend group does challenges every week now. The leaderboard is the most competitive thing we've ever done. I love it."
"I lost $10 the first week. That was enough. I haven't missed a gym day in six weeks. Best $10 I ever spent."
