barabar keeps track of who paid for what across trips, flatmates, and everything else shared — then works out the fewest payments that put everyone even.
Coming to iPhone
Equal shares, exact amounts, percentages, or shares — and more than one person can have paid for the same thing.
Each group keeps its own currency, and an individual expense can be in another. Amounts are held in whole minor units, never as floating point.
Add an expense on a plane or in a basement. It is saved on your device first and syncs when there is a connection.
Send a read-only link and someone can follow the group's history in a browser. They can read; they cannot change anything.
barabar works out who should pay whom so the group clears with the smallest number of transfers, not a web of small ones.
You invite people by email, but nobody else in the group sees it. Your ledger is stored separately per account on your device.
