What each one actually does for uninstalling
Both tools solve the same underlying problem: dragging an app to the Trash on macOS leaves behind preference files, caches, and support folders scattered across your Library directory. Over years of installing and removing software, those leftovers accumulate. CleanMyMac's uninstaller module scans your installed applications and their associated files as part of its broader suite, presenting them for removal alongside its other cleanup categories. AppCleaner does the same core job, but as its entire purpose: drag an app onto it, and it searches for every related file so you can review and delete them together.
For the uninstall job specifically, the mechanisms are similar in effectiveness. The meaningful difference is everything AppCleaner doesn't do: it has no junk-file scanner, no malware check, no memory tool, and no ongoing background presence. It opens, does its one job, and you close it.
Where CleanMyMac wins
One app for many jobs. If you also want junk cleanup, malware scanning, and memory management, having the uninstaller built into the same suite means one interface for everything, rather than switching between several apps.
Ongoing maintenance features. CleanMyMac includes scheduled scans and system health monitoring that a single-purpose uninstaller has no equivalent for, since that's simply outside AppCleaner's scope.
Where AppCleaner wins
Price. Free versus $39.95-89.95 a year is not a close comparison if uninstalling is the only job you need done.
Focus. AppCleaner does one thing and does it without a dashboard, a scan summary, or any upsell toward other features. Drag, review, delete, done.
Footprint. At roughly 4MB, AppCleaner is a tiny download with no background processes running between uses, unlike a full suite that may run scheduled scans or a menu-bar agent.
Which one should you use?
If uninstalling apps cleanly is genuinely the only job you need handled, AppCleaner does it for free with no reason to pay for a suite. If you also want junk cleanup, malware scanning, and memory management in one place, CleanMyMac's bundled uninstaller is one part of a larger, paid package, and the question becomes whether you'll use the rest of the suite regularly enough to justify the subscription.
Some people run both: AppCleaner for day-to-day app removal, and a separate tool for whichever other single job they actually need. That combination is often cheaper overall than a full suite subscription if you only need two or three of its features.

What "leftover files" actually means in practice
It's worth being concrete about what either tool is actually finding, since "leftover files" sounds abstract until you see it. Dragging an app to the Trash removes the application bundle itself, but macOS apps routinely write preference files to ~/Library/Preferences, cache data to ~/Library/Caches, and sometimes larger support files to ~/Library/Application Support. None of this is deleted automatically. Over years of installing and removing software, these folders accumulate genuinely surprising amounts of orphaned data, often gigabytes across dozens of long-forgotten apps. Both AppCleaner and CleanMyMac's uninstaller module search these specific locations by matching file and folder names to the app's bundle identifier, which is why a simple drag-to-Trash misses what a proper uninstaller catches.
A smaller, unrelated option worth knowing
We make Shiny, so we should disclose that upfront. Shiny is not an uninstaller and doesn't compete with either app here; it frees memory instead, for $4.99 once. If the only CleanMyMac feature you'd actually use is its memory cleaner rather than its uninstaller, that's a separate comparison worth reading about in Shiny vs CleanMyMac.
A quick way to test either tool before deciding
Before paying for CleanMyMac specifically for its uninstaller feature, it's worth trying AppCleaner first, since it's free and takes under a minute to install. Uninstall an app you no longer need with it, then check the same app's usual Library locations manually to see what was found. If AppCleaner catches everything you'd expect, you have your answer for that one job at zero cost. If you're already using CleanMyMac for other reasons (junk cleanup, memory, malware scanning) then its bundled uninstaller is simply one more feature you're already paying for, and there's little reason to also install AppCleaner alongside it.
