The problem

Tracking shared expenses, loans between friends and personal budgets across separate spreadsheets meant no one actually knew who owed what, or where their money was going.

What we built

Built a multi-user finance app with per-user Google OAuth, group expense splitting (including itemized, not just even splits), cross-user linked lending that both sides can see and settle, recurring transactions, PDF/CSV statement exports, and real push-notification reminders — consolidating what started as three separate personal forks into one shared, properly authenticated product.

The result

In active daily use by multiple real users tracking real shared expenses and settling real balances between each other.
