Expance

Expance is a mobile-first expense, income and settlement tracker for shared money. In project spaces, co-founders see who paid what, a live contribution balance, settlements and each member's profit share. In personal spaces, families track who spent what, set monthly budgets that warn during the month, and see how much landed on the credit card. Multi-currency entries lock in the exchange rate on the day, receipts attach to entries, and people join a space by scanning its QR invite. Installable as a PWA, with a design inspired by the bahi khata ledger.
