Call It Even: Split Expenses is a mobile and web application designed to track shared costs among groups of people. Its primary function is to manage expense splitting in real time, showing each participant who owes whom and allowing them to settle debts with a single tap. The app handles receipts by scanning them with a camera, extracting individual line items, and assigning each item to the person who ordered it. Tax and tip are then divided proportionally based on what each person consumed, rather than splitting the total evenly. Users can also add expenses manually, choosing to split them equally or by exact amounts, and select which participants are included from a searchable list. The app supports multiple currencies, tracking each expense in its own currency and maintaining separate balances per currency, which is useful for international trips. It allows users to generate a read-only link for any trip or expense that friends can view in a browser without needing an account. Guests (people not on the app) can be added to a group, and their shares are still tracked. Settlement is handled by recording a payback, which resets the balance to zero; users can settle via cash, Venmo, bank transfer, or any other method. Friends can be added by scanning a QR code, eliminating the need to remember usernames. A complete activity timeline logs every expense, edit, and payment, providing a transparent record. Typical use cases include roommates splitting household bills, groups on trips (from a single dinner to a multi day trip with ten people), and any event where costs are shared among multiple people. The workflow is straightforward: a user adds a cost (amount, who paid, and what it was for), selects the participants and the split method, and the app instantly shows who owes whom. The user then records the payback when it happens, and the balance resets. The app is free to use on iOS and web. It does not require any bank or card details, never moves money or charges fees, and users can export or delete their data at any time. There is no setup or learning curve; the app is intended to replace spreadsheets and awkward follow up messages about money owed.
