I built TimeTracker, an offline-first time tracking Progressive Web App that runs entirely in your browser.

It’s aimed at freelancers (and anyone else who just wants a simple tracker) who don’t want accounts, cloud sync, or their work history living on someone else’s server. Your data stays on your device, and you can export it anytime.

What it does today:

Start/stop timers quickly, and track time across multiple projects

Timesheet-style view to review and edit entries by project/date

Calendar view to visualize daily/weekly work

Reports & analytics, including generating PDF reports

Import/export as JSON for backup/migration

Project management: hourly rates + basic cost tracking

Any UX friction you hit (especially on mobile, install-as-app, etc.)
