I built Time Tracker, a lightweight macOS desktop time tracker focused on staying out of the way.

It’s local-first (no account), works offline, stores data locally (SQLite), has a quick start/stop timer + editable history/totals, and can generate simple PDF invoices from a date range.

P.S. Feel free to leave a star if you like it.

Cheers!
