Split It

Split It is an iOS app that turns the end-of-dinner "who owes what" ritual into a ten-second drag-and-drop. Point your camera at the receipt, and AI reads it into editable line items; drag each item onto a person (or into the middle for shared plates), and tax and tip distribute themselves proportionally by what everyone actually ordered.

Why I Built It

Splitting an itemized bill is equal parts social friction and mental math. Existing apps make you type the whole receipt in by hand, which nobody does at the table — so everyone just splits evenly and the person who ordered a salad subsidizes the person who ordered a steak.

Features

• AI receipt scanning — GPT-4V turns a photo into editable line items
• Drag to assign — flick items onto people; a center circle handles shared items
• Fair math — tax and tip split proportionally by each person's subtotal
• SharePlay — the whole table splits together live over FaceTime
• Share the damage — send totals as an image or text, with receipt history and lifetime stats

The Stack

Native SwiftUI on iOS 17+ with SwiftData persistence and a StoreKit 2 Pro upgrade. The backend is Next.js on Vercel with Upstash Redis handling scan quotas and App Store entitlement verification. Currently headed to the App Store.
