CleanApp could be a decent app...I spotted the MacBytes link to this AppleMatters article, and it does look good. I haven't used it though, so I can't personally vouch for it, as I can AppZapper. (I also picked up AppZapper for free through a MacZOT offer awhile ago, so you can't beat that price.)
I'm not sold on the archive feature of CleanApp yet. If I want to reinstall an app later, I'll leave the prefs in place and not zap them. If I want to archive the app, I'll save the .dmg in came in. But I suppose it could be useful, and if I tried it I might very well wonder how I lived without it, but from the outside, it's not a must-get for me yet.
