How it works

Three steps, zero confusion.

🎉01

Start a pool

One person is commissioner — they create the event and post the questions. 'Will Jake stay out past 4am?' 'First to cry at the wedding?'

📈02

Friends place bets

Everyone joins with the invite link. Pick Yes or No, set your price, and watch the odds shift as friends pile in.

💸03

Settle up

Commissioner calls the results. The app calculates who owes who and shows the minimum transfers. You Venmo the rest.

Good for any occasion.

If you can turn it into a Yes/No question, you can bet on it.
