ActivityWatch - Open-source time tracker runs on http://localhost:5600/
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.
TODO: An alfred plugin that will log what i'm doing into activitywatch using it's API. Has someone already done this?
