As in price, not open source code.
Pro Prefpane style app
AppTrap installs a daemon that runs in the background monitoring the trash, when you drag an app to the trash it will search for associated .plist files that have been left behind and ask to move them to the trash. In other words, AppTrap launches and does the work for you automatically. All you have to do is uninstall apps the old fashioned mac way by dragging apps to the trash.
Cons
Con Non negligible processor ressources use
For such a tiny app, with a very limited function, idle most of the time, it actually is using non negligible processor ressources (frequently around 2% when not in use, and totalling more than Alfred, Dropbox or 1Password, for example).
Con Not Supported in Big Sur
Con Gets some things, not everything
This is thorough enough in cleaning up most of the cruft that gets left behind by applications, but might not get everything for the more invasive applications, especially if some of the files have privileged permissions.
Con Requires using Finder
Does not work if you trash app using alternate file browser like Path Finder.
