I spent a long time looking for a good screen time app for Windows and never found one I liked, so I built one.

Screentime shows exactly where your day goes:

• Every app, every hour, on one 24-hour dial

• Click an app to see exactly when you used it

• Your whole week at a glance

• Export your sessions as CSV or JSON

It's native and lightweight, written in pure Rust, with SQLite for local storage. It never touches the internet: no account, no telemetry, nothing leaves your PC. It only stores app names and times, never window titles, URLs or keystrokes. It asks before starting at login.

Free and open source. Built with Claude Code.
