AppCleaner

AppCleaner is a free Mac utility from FreeMacSoft that finds and removes every file an application leaves behind — preferences, caches, logs, and support bundles — so your drive stays genuinely clean after an uninstall.

What is AppCleaner?

AppCleaner is a lightweight, purpose-built uninstaller for macOS that goes far beyond dragging an app to the Trash. When you move a standard Mac app to the Trash, the binary disappears but a scattering of support files — buried in ~/Library subfolders the Finder hides from you — quietly accumulates over months and years. AppCleaner hunts down every one of those orphaned files and presents them in a single, confirmable list before anything is deleted.

It has been around for well over a decade and remains one of the most-recommended tools in any Mac power-user's arsenal, precisely because it does one job and does it with no drama. Drop an app onto the AppCleaner window — or simply find it in the built-in app browser — and within seconds you get a complete manifest of everything that app owns on your machine.

What does AppCleaner do best?

AppCleaner's standout feature is the depth and accuracy of its file discovery. Unlike some competing tools that scan by app-bundle name alone, AppCleaner correlates bundle identifiers, developer signatures, and known Library paths to catch preference files that apps deliberately tuck away under non-obvious names. I've regularly seen it surface 50–200 MB of residual data from apps I assumed were already gone.

• SmartDelete — enable this in Preferences and AppCleaner intercepts any app you drag to the Trash, automatically surfacing the full removal checklist without any extra steps.
• App browser — a sortable list of every installed application, filterable by size. Great for auditing trial software you forgot to remove.
• Widgets & Preference Panes — the removal engine covers macOS widgets, system preference panes, and plug-ins, not just standard .app bundles.
• Zero bloat — the app itself weighs a few megabytes, launches instantly, and asks for nothing except the permission to move files to the Trash.

I reach for AppCleaner every time I'm done evaluating a trial app. The alternative — manually trawling ~/Library/Application Support, ~/Library/Preferences, and ~/Library/Caches — takes five minutes and still misses things.

Is AppCleaner free?

Yes — AppCleaner is completely free to download and use with no feature restrictions, no nag screens, and no subscription. FreeMacSoft accepts voluntary donations, but nothing is gated behind a paywall. For a utility this polished, that generosity is genuinely unusual.

If you find yourself comparing it to paid alternatives like CleanMyMac X, it's worth noting that AppCleaner handles the uninstall workflow better than most commercial tools I've tested, though it doesn't touch duplicate files, large-file finders, or privacy cleaners — that's a deliberate scope decision, not a limitation.

Who should use AppCleaner?

Any Mac user who installs and removes software regularly will benefit, but AppCleaner is especially valuable for power users running a tight-storage Mac — a 256 GB MacBook Air, for instance, where every reclaimed gigabyte matters. Developers who cycle through a lot of beta software, designers who trial multiple creative apps, and anyone maintaining a fleet of Macs as part of an IT workflow will get the most out of it.

It's also a smart first install on a new Mac, before you accumulate the clutter. Enabling SmartDelete from day one means you'll never accidentally leave residual files behind.

What are the best AppCleaner alternatives?

The paid tier is dominated by CleanMyMac X (€34.95/year), which bundles an uninstaller alongside a malware scanner, performance monitor, and space analyser — more comprehensive, but considerably heavier and subscription-gated. AppZapper is a classic one-time-purchase alternative with a satisfying drag-and-zap interface, though it hasn't been updated as actively. iTrash sits in a similar price bracket to AppZapper and is worth a look if you want a commercial receipt for every removal.

For most people, though, AppCleaner's free, frequently-updated build makes paid alternatives hard to justify for the uninstall use case specifically. Where CleanMyMac X earns its fee is the other maintenance tasks it bundles — if you only want clean uninstalls, save your money.
