"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 help you keep track of time spent on different projects, kick bad screen habits, or just understand how you spend your time."
