ActivityWatch is an app that automatically tracks how you spend time on your devices.

It is open source, privacy-first, cross-platform, and a great alternative to services like RescueTime, ManicTime, and WakaTime.

It can be used to keep track of your productivity, time spent on different projects, bad screen habits, or just to understand how you spend your time.

  • Browser extensions: Track the active tab using the extensions for Chrome and Firefox.
  • Editor plugins: Track how you spend time writing code with editor watchers.
  • Privacy: Data is stored locally and doesn't leave your device, we put local and privacy first.
  • Cross-platform: Runs on Windows, macOS, Linux, and Android.
  • Synchronization: Sync your activity between your devices. (We're working on it)

You can use ActivityWatch to:

  • Track how much time you spend on different projects.
  • Get an overview of time spent on apps, games, videos, and music.
  • Manage your bad screen habits.
  • Measure your work-life balance.

About the maintainers

ActivityWatch was founded by brothers and current maintainers Erik Bjäreholt and Johan Bjäreholt. We started building ActivityWatch because we thought something like it should exist (it didn't), so we decided to build it ourselves. You can read the History page in the docs for more about the project's origins.

We don't work on ActivityWatch full-time, so development may slow at times. But we think that ActivityWatch is important software (if you agree, donate!), and we're building for the long term. We want to build an as useful tool as possible for as many people as possible.

Over the years, many significant contributions have come from the community, and we hope to see them increase over time. For details on who has contributed what and how much to ActivityWatch, check out the contributor statistics.
