Personal Finance Tracker Mobile App
Personal finance tracking lived in scattered notes and manual spreadsheet updates — no quick mobile view of balances, monthly spending, or secure access on the go.
We built a private finance tracker where users manage bank, cash, and wallet accounts from their phone. Transactions sync to Google Sheets via Apps Script — giving spreadsheet flexibility with a native mobile UX, month-by-month dashboards, and app-level security.
The Challenge
Building a secure personal finance app without running a backend server — while still keeping data editable in a spreadsheet and accessible offline-first on mobile.
Our Solution
An Expo React Native app with Zustand state, Victory Native charts, PIN and biometric unlock via Secure Store, and a Google Apps Script API layer that reads/writes Sheets as the database — no server to maintain.
The Results
- Multi-account dashboard — bank, cash, wallet & personal
- Income, expense & transfer logging with categories
- Monthly charts & spending reports
- PIN + biometric app lock
- Google Sheets backend — no server required
- Android APK build via EAS
