+      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.
