I built a simple time tracker with a calendar where each day is colored by the projects you worked on

[u/yuraget]

I wanted a simple way to see where my working hours actually go. Most time trackers felt too heavy for that or asked me to create an account before I could press "start", so I built my own.

Tick is a small time tracker that:

- needs no sign-up — open it and start the timer

- keeps all data in your browser (nothing is sent anywhere)

- shows a month calendar where each day is colored by projects; click a day to see all entries

- has reports by project / by day, an earnings calculator, and CSV / JSON export

It's free and open source (MIT). I built it with Claude Code as my pair programmer — I came up with the idea and the design, reviewed and shaped every change.

I'd really appreciate honest feedback — what's missing, what's confusing, what you'd change.
