Project Overview
This application is designed to simplify the way people manage shared expenses within groups. Users can create and join groups, log their individual and group expenses, and have the system automatically divide the costs among members. The platform includes a robust settlement module, allowing users to track who owes what, view pending balances, and settle up easily through direct payment links. The system ensures transparency and accountability, helping users avoid the confusion that typically comes with shared finances. Its intuitive interface and real-time updates make it an ideal solution for roommates, friends on trips, or teams managing collective budgets.
