Description
Group expense splitter for trips and shared events, with live balance updates, flexible split methods, settle-up recommendations, and progress tracking until everyone is even.
Prompt
Create an expense splitter app for groups.... Users create an event like a trip or dinner and share a unique link (per event) with friends. Everyone can add expenses from their own device. Each expense has a description, amount, who paid, and how it is split - equal, custom, or by percentage. The app shows who owes whom and keeps a running balance for each person. It also shows a simple settle up view that tells people who should pay who to get even. Users can mark payments as settled and see the group progress toward being fully settled. Use a clean, mobile first UI with tabs for expenses, balances, and settle up. All data should stay in sync so everyone always sees the latest state when they use the app.
