I needed to track hours across clients and turn them into invoices without paying for another tool. It became a time-tracking and invoicing app I use for freelance work.
What it does
- Weekly calendar with UTC-based tasks, drag-and-drop, and timers you can pause
- Invoices go draft → final. An invoice only gets a number when you finalize it
- Exports to PDF, CSV, and PNG
- Monthly reporting with client-hours search and Recharts dashboards
- Auth: email/password, Google and Apple, and WebAuthn
- A one-time import from the localStorage version that came before it
Build notes
React 19 + Vite on the client, Supabase for auth and Postgres with row-level security. PDFs are generated in the browser with jsPDF and html2canvas. No server needed to make an invoice.
Time is stored in UTC and shown in the viewer's timezone, so the hours stay correct.
