Kotisso keeps the books for any group that shares money: a flatshare, a trip abroad, separated parents splitting their children's costs. Everyone notes what they paid. Kotisso keeps the balances and proposes the shortest set of transfers to settle up. Four split modes, 48 currencies with the rate frozen at entry, receipt photos, CSV and PDF export, and it opens offline. The whole accounting side is free, and always will be. 16 languages, right-to-left included. No bank connection, ever.
I built Kotisso after one holiday too many spent rebuilding a spreadsheet on the drive home.
Three decisions shaped it.
Money is stored as integer cents, and the sum of a group's balances is always exactly zero. That invariant is asserted after every write, and it caught every accounting bug I had before any of them reached a screen.
The accounting is free and stays free. A free account sees fewer rows, never different numbers: expenses outside the twelve-month window still count in the balances, in the group total and in the per-category breakdown. A truncated statement would be a false statement.
No bank connection. Nothing to link, nothing to leak, and it works in a night market where you type the rate you actually got and it stays frozen at that value forever.
It speaks 16 languages including Arabic right to left, installs as a PWA and opens offline. Happy to answer anything, including what it does not do.
