Built out of pure spite for the group chat
Every friend group has the planner. The one who finds the tickets, fronts the money, books the place, and then spends three weeks collecting $80 from six people who "totally forgot".
Whosin exists because that person deserves better tools. Not a ticketing site, not a bank, not another chat app. Just the missing piece: a way to make "I'm in" mean something before anyone spends a dollar.
The idea is old. Put up or shut up. We just made it take thirty seconds and feel good to use.
Commitment is kindness
Locking in early is the nicest thing you can do for the person planning. We make it the easy default.
Money talk is awkward
So the app does it for you. The max is public, the split is automatic, and nobody has to chase anybody.
We don't sell you anything
Buy your tickets, flights, and dinners wherever you like. Whosin only handles the "who's paying" part.
