AppCleaner vs Uninstalr

AppCleaner is a free macOS utility for uninstalling unwanted applications and finding the files they leave behind. Drag an app into its window to see related files distributed across the system, review the list, and choose what to delete. Version 3.7 improves searches in Application Scripts and asks for Full Disk Access; without that permission, some files may remain. It can locate files associated with system apps, but cannot remove those apps. Downloads cover several macOS generations: version 3.7 for macOS 15 and later, 3.6.8 for macOS 10.14 up to 15.6, 3.6 for macOS 10.13, and 3.4 for macOS 10.10 up to 10.12. Version 3.6 added native Apple M1 support. AppCleaner can detect applications inside disk images and offer to remove the image file instead. Its login item appears in System Settings, and a preference can hide protected apps. The download page also notes a Sparkle updater security fix in version 3.7 and HTTPS updates since version 3.2.

Uninstalr is a Windows app for uninstalling software, with leftover scanning, forced removal and batch uninstall. Before removal begins, it shows paths that would be deleted and lets users exclude paths; the maker recommends reviewing them and creating a backup first. Its custom engine can continue an uninstall without further interaction once started. The app detects 16 listed types, including Microsoft Store apps, package-manager apps and games from several platforms. Users can search, sort and filter one installed-app list, and disk use is calculated in real time. Uninstalr also displays app country of origin; the maker says this feature works locally without sending data elsewhere. Portable and setup versions have the same functionality, and the download page lists Windows 11, 10, 8 and 7. The free plan is available for personal, business and client-computer use. Uninstalr Pro is $39 a month (billed One-time payment; 1 computer); the Pro and WinFindr Pro bundle is $56 a month (billed One-time payment; 1 computer).
