This is the finance app I wanted for myself. English and Spanish. Envelopes, investments, giving, and a few currencies.
What it does
- Dashboard with balance, monthly spend, and how those changed
- Envelope budgeting with a progress bar per pool
- Movements with full history and a calendar you can click into
- Investments and net worth next to day-to-day spending
- Imports: CSV in the app, plus Santander statements
- Multi-currency (20 currencies, EUR as the base) with conversion
- Spending charts by category, via Recharts
Build notes
Next.js 16, React Server Components, Supabase (auth, Postgres, row-level security), Tailwind CSS v4, Base UI. Soft neutrals, tabular-nums on every number, green for up, rose for down. Phone gets a bottom nav. Desktop gets a sidebar.
Status
Live, and I'm still adding to it. Lately: calendar, transfers, net worth, CSV import.
