Split costs
Who owes whom, or a budget split by share.
What it does
- Between friends: add the people, then each expense: how much, who paid, and for whom (everyone by default, or tap names to leave some out). The tool gives the fewest transfers so everyone is even.
- By share: an amount (a shoot budget, a shared bill) split by shares (1, 2, 3…) or by percentages. Leftover cents go to the biggest shares, so the total is exact.
- Everything stays on your device.
