PearcleanerUnderrated
A free Mac app cleaner that finds the leftovers drag-to-trash leaves behind.

Best for
Mac users who uninstall apps regularly and want related caches, preferences, and support files removed too.
Why it deserves attention
Pearcleaner scans an app bundle and lists the caches, preferences, application support files, launch agents, and other leftovers tied to it, then removes them together after you review the list. It also finds orphaned files left by apps that are already gone, shows file sizes before deletion, and offers a minimal SwiftUI interface plus a CLI for scripted cleanups. It has about 15,000 GitHub stars and is free to use. It is source-available under a fair-code license rather than OSI open source, and cleanup tools always deserve a look at the review list before confirming, especially for apps that share support folders.
