Settles in 3 transfers

01 / Expenses

Even, exact, or shares

Add who paid and how it splits. Multi-currency entries convert at the day's rate and keep the original amount.

02 / Balances

Positions, not a transaction wall

The main view is four numbers: what each person is up or down, with the ledger one tap behind it.

03 / Settle

The fewest possible transfers

Settle-up collapses the debt graph, so nobody sends three payments to close a weekend.

The group chat is not a ledger.

Share one link, everyone adds what they paid, and the arithmetic stops being somebody's job.
