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.

Hey PH 👋 I built JotSplit because every expense splitter I tried made me fill out a form. Amount field, payer dropdown, participant checkboxes — for a $12 lunch. I wanted to just write it down like a note. So the input is one sentence and the app does the structuring. The part I'm most opinionated about: the AI never does math. It only pulls out fields. Every calculation is deterministic code, and there's a mandatory review page before anything is written. I didn't want an LLM quietly getting someone's share wrong. I'm a solo dev and this is my first shipped app. 1.1 just went live with push notifications. Happy to answer anything — architecture, the Supabase setup, what App Store review was like, whatever.
