- Recurring bills — see what's due in the next 7 days on the home screen and mark it paid in one tap, which logs the transaction for you
- Savings goals — set a target, add funds over time, watch the progress bar fill
- Insights — budget progress, a category breakdown with a donut chart, and a 6-month income/expense trend
- Data export — CSV, JSON, or a fresh Google Sheet, on demand
- Light/dark mode
- Thai / English interface
- Installable PWA — add to your home screen, keeps working offline
- Responsive — mobile-first bottom nav, wider multi-column layout on desktop
Tech
Vanilla HTML/CSS/JavaScript (ES modules), no framework — bundled with esbuild and deployed by a GitHub Actions workflow. Data and auth run on Supabase (Postgres + Google OAuth); the Google Sheets export talks to Google's Sheets API directly via Google Identity Services. Hosting is GitHub Pages; offline/installability comes from a small hand-written service worker and web manifest.
Built with Claude Code.
