LARRYMCJ  Though I'm a registered customer of several similar apps (including AppZapper) I find AppCleaner to be the best...by far. In my tests it always found more (usually all) files associated with the application being deleted. AppZapper has to be the worst at this...it probably finds about 50% of the associated files. Another very nice feature of AppCleaner is by simply moving an application to the trash AppCleaner will find all that app's associated files and ask if you'd like to also delete them.

STEPHAN213  One of the first apps I always install on a new mac.

Uninstallers are very much needed for mac, and Appcleaners Smartdelete is the best and easiest way to get rid of files thoroughly, without even having to run the app.

ICONZ113  Ive used every uninstaller including cleanapp DUBIEXX, and I agree that clean app looks good, but I think appcleaner performs the best, and thats what counts.

DRDUL  Despite having purchased a licence for AppZapper a few years ago, I now use AppCleaner exclusively. The big reason I switched is that AppCleaner will successively delete apps without the need to re-authenticate when used from a non-admin account. Authenticate once, and then you can delete as many apps as you want without typing your admin password over and over again (eventually, after about 5 minutes, you'll need to re-authenticate).

DEATHCABFORSEAN  I Havn't had appcleaner for very long, but it has impressed me. I was close to buying appzapper at one point, partly cos i loved the zapp sound effect, but mostly for the lifetime update guarantee, and the fact it didn't seem too much to pay to be able to keep my mac clean and uncluttered (don't want our macs turning out like every pc on the planet), but appzapper hasn't been updated for 2 years, so it seems a pointless guarantee. appcleaner has a cool cube flip-around view when you choose the app to clean, no cool zapp soundeffect, but for a free app works perfect. I got rid of iGTD2 with it, and after cleaning it and spotlighting one file was still there, but i just put it through appcleaner a second time and every trace was removed, no worries, just have to be patient, but considering it's free, seems fine.

MBHOCKEY  Terrific App! Better than AppZapper, and free!

RORO01  MANY THANKS!!!

The best of its kind. Works as described. I wonder if it's possible to add a feature to detect preference files which are not associated with any application, i.e files of applications where we have deleted the applications (before we had AppCleaner) but forgot to delete their preference files.

ASDFASD  Perfect! Great look, stable, quick and free... You can not ask for more. Only problem is that it has not been updated for a while...

CHAWKNZ  Who says you don't need to uninstall on a Mac? Well, really you don't but if you don't look carefully, your preference folders will get filled up with applications from ages ago.

This application does a great job at finding most files associated with an app and provides a clean, easy way to see and clear these files. This program has become a staple of my desktop, residing where the classic Mac's trashcan used to be.

Best of all? It's free.

Thank you!
