About Kotisso

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.
