A mobile application for splitting group expenses among friends, roommates, and travel companions. The app tracks shared expenses, calculates optimal settlements, and generates UPI payment links for instant settlement. Features include group management, receipt scanning, and expense analytics.
Problem Statement
Indian college students and young professionals frequently share expenses for food, trips, rent, and subscriptions. Tracking who owes whom becomes complicated in groups, leading to awkward conversations and forgotten debts. While apps like Splitwise exist, they lack UPI integration for instant Indian payments and charge premium fees for basic features.
