Nektony App Cleaner & Uninstaller is a macOS utility that surgically removes applications and every file they scatter across your system — preferences, caches, launch agents, and support bundles — leaving no orphaned data behind.
What is Nektony App Cleaner & Uninstaller?
App Cleaner & Uninstaller by Nektony is a dedicated Mac application removal tool that goes far beyond dragging an app to the Trash. It scans your entire file system for the auxiliary files that macOS apps routinely plant in ~/Library, /Library, and elsewhere, and presents them in a single, reviewable list before you delete anything. The result is a genuinely clean uninstall rather than the half-removal that catches so many Mac users off guard.
I've been running it on an M-series MacBook Pro that doubles as my primary dev machine, where the constant churn of trial apps and developer tools means the Library folder becomes a graveyard surprisingly fast. App Cleaner & Uninstaller is the tool I reach for when I want to be certain something is truly gone.
What does Nektony App Cleaner & Uninstaller do best?
Its strongest suit is the completeness of its removal pass. When you drag an app into the window — or select it from the built-in browser of everything installed on your Mac — the scanner surfaces related files grouped by type: application support, preferences, caches, plugins, login items, and launch daemons. You can review, deselect individual items, and then delete with confidence.
- Service management: a dedicated Services panel lists every launch agent and daemon registered on the system, so you can disable background processes without hunting through Terminal or LaunchControl.
- Leftovers scanner: a separate sweep finds remnant files from apps already deleted the old-fashioned way — the digital equivalent of finding furniture marks on the carpet after a move.
- Reset app: you can wipe an app's preferences and caches without uninstalling it, which is a faster fix for misbehaving software than a full reinstall.
- Startup management: login items are listed and togglable in one place, a task macOS's own System Settings interface makes awkward beyond the first few entries.
How much does Nektony App Cleaner & Uninstaller cost?
App Cleaner & Uninstaller is free to download and use for core uninstall tasks. Nektony offers a Pro upgrade — available as a one-time purchase or directly through the Mac App Store — that unlocks the full Leftovers scanner, the Services manager, and a few additional batch-removal conveniences. The free tier is genuinely useful and not artificially crippled, which is refreshing compared to the aggressive paywalls common in this category.
Who should use Nektony App Cleaner & Uninstaller?
Anyone who installs and removes software regularly will benefit, but the tool earns its keep fastest for developers, designers, and power users who trial a lot of software. If you've ever wondered why your Mac's Library folder has grown to several gigabytes despite removing apps, this is the tool that explains — and solves — that mystery. It's equally useful for less technical users who simply want a trustworthy "remove this completely" button rather than the ambiguity of the Trash.
If your Mac is essentially a display kiosk that runs three apps and never changes, you probably don't need it. Everyone else does.
What are the best Nektony App Cleaner & Uninstaller alternatives?
The most direct competitor is CleanMyMac X from MacPaw, which bundles an uninstaller inside a broader system-maintenance suite. CleanMyMac X costs significantly more and is subscription-based, but it covers more ground (malware scanning, disk cleanup, privacy tools). If you want only deep-uninstall capability without the subscription overhead, App Cleaner & Uninstaller is the tighter, more affordable choice.
AppCleaner by FreeMacSoft is a long-standing free alternative with a simpler drag-and-drop interface, but it lacks the Services manager, the Leftovers scanner, and the Reset App feature. TrashMe 3 sits somewhere between the two in terms of feature breadth. For users who live in the terminal, brew uninstall --zap covers Homebrew-managed apps surprisingly well — but nothing in the CLI ecosystem matches App Cleaner & Uninstaller's visual scan for non-Homebrew software.
How does Nektony App Cleaner & Uninstaller compare to CleanMyMac X?
App Cleaner & Uninstaller wins on price and focus. CleanMyMac X wins on breadth. The Nektony tool does one job — removal — with more granular control and transparency: you see exactly which files will be deleted before you confirm, rather than trusting a black-box algorithm. CleanMyMac X's uninstaller is competent but buried inside a subscription product that many users find over-engineered for their needs. If deep-cleaning and malware scanning matter to you, CleanMyMac is worth it. If you want surgical, trustworthy uninstalls at a fair price, App Cleaner & Uninstaller is the better call.
