App Cleaner & Uninstaller
App Cleaner & Uninstaller is a Nektony utility for thoroughly removing Mac apps and related files while also helping manage startup items and extensions.
What is App Cleaner & Uninstaller?
App Cleaner & Uninstaller is a macOS utility published by Nektony LLC. Its main purpose is to help users remove applications more completely than dragging an app to the Trash, by finding associated support files such as caches, preferences, and other leftovers. Nektony also presents it as a tool for managing startup programs, login items, browser or system extensions, and outdated software from one interface. Typical users encounter it when they want to uninstall apps cleanly, review what launches at sign-in, or inspect software installed on a Mac. The app integrates with standard macOS application and library locations, so it may request access needed to scan installed apps and their related files. It is commonly distributed directly from Nektony as a downloadable Mac utility and is part of the broader MacCleaner product family.

Safety overview
Status: Mostly safe
This is a legitimate commercial Mac utility from Nektony LLC, not generally known as malware. It can remove application files and related data, so the main risk is accidental deletion of app settings, extensions, or support files you still want. Review removals carefully, especially for shared components or login items.
Recommendation: Keep it if you actively use it to uninstall apps, review extensions, or manage startup items. If you no longer use it, removing it is usually reasonable, but check whether you rely on its cleanup monitoring or software management features first.
