JotSplit

Type dinner 120, me and Sarah, I paid and JotSplit extracts the amount, payer, and participants. No forms, no dropdowns. The AI only extracts fields. Every calculation is deterministic code, and nothing counts until you confirm it on a review page. An expense you didn't approve doesn't exist. Balances are never stored — always computed, so they can't drift. Built solo. 1.1 just shipped with push notifications. iOS, free.
