Free to join. Stake $5–$100 on a promise to yourself. Keep it and your stake comes back. Break it and your friends split the pot.
No app to install. No credit card to start. Invites going out weekly.
How it works
No habit tracker. No journalling. No willpower. Just stakes.
"Run 3x this week." "No doomscrolling after 10pm." Set a deadline, pick who holds you to it, decide if you want to challenge a friend to do it with you.
Your card is held (not charged) via Stripe until the promise resolves. A small processing fee covers Stripe's costs and is disclosed before you confirm.
Keep your promise and your stake comes back. Break it and your friends split the pot (minus our 15% platform fee). Streaks, badges, and a weekly leaderboard come for free.
Why it works
We didn't invent any of this. Behavioural economists have been saying it for decades. Promise just makes it one-tap easy.
Losing $20 feels roughly twice as bad as winning $20 feels good. That's loss aversion — the single strongest behaviour nudge we've got. Promise puts real money on the line so your future self can't quietly opt out.
Goals you tell friends about are 2–3× more likely to stick. Goals with money attached stick harder. Promise stacks both so there's nowhere to hide.
Vague check-ins let you lie to yourself. Daily photo, text, or screenshot evidence doesn't — and your streak lives and dies by the receipts your friends can actually see.
