FinFast — Personal Finance & Linked Loans
FinFast helps individuals track income, expenses, and savings, and uniquely links users by mobile number so informal loans between friends or family are recorded on both sides. When you lend to someone, their app reflects the liability automatically through a Python API.

People tracked personal budgets in notes apps but had no reliable way to record loans between individuals — leading to disputes and forgotten balances.

Outcomes
- Income, expense, and savings tracking per user
- Loan requests linked between two mobile numbers
