There is a great tracking app called lifecycle that can do location and activity tracking on your phone. You can export the data from it, so I wanted to import it into Activitywatch to better understand where I am during the AFK times. You can find it here: https://github.com/RTnhN/aw-watcher-lifecycle
Note that the status of the app is a little unknown. The developer’s original webpage is down, but the other apps that they develop have working developer webpages. That is primarily why I don’t want to add it to the list of watchers on the docs page.
