ActivityWatch is a free, open-source automated time‑tracker that records how you spend time on your devices. It stores all data locally and provides a web UI and desktop client for analysis.

Use cases

  • track how much time I spend on each application or website
  • monitor my screen time habits across Windows, macOS, Linux, and Android
  • generate daily or weekly reports of my productivity
  • visualize time spent on projects, games, and media
  • track coding activity in editors like VS Code or Vim

When to choose

  • when you need a privacy‑first time tracker that keeps data on your device
  • if you want a cross‑platform solution that works on desktop and Android
  • when you prefer an extensible system with custom watchers and plugins
  • if you want a free alternative to commercial services like RescueTime

When to avoid

  • if you require cloud‑based syncing out of the box
  • when you need deep integration with enterprise monitoring tools
  • if you prefer a lightweight CLI‑only tracker without a GUI
