Cleaner-App
App Cleaner & Uninstaller is a macOS utility from Nektony for removing apps and related leftover files, with extra tools for app management.
What is Cleaner-App?
App Cleaner & Uninstaller is a Mac utility published by Nektony that focuses on uninstalling applications more completely than dragging them to the Trash. It scans for related support files such as caches, preferences, launch items, and other leftover data that may remain after an app is removed. Nektony also presents it as a broader app-management tool, with features for reviewing startup programs, extensions, and available software updates. On modern macOS versions, it may request Full Disk Access so it can inspect app-related files stored in protected Library locations. Users typically encounter it when trying to free storage, remove stubborn software, or audit what applications and background items are installed on a Mac. The bundle ID com.nektony.App-Cleaner is associated with this product family, and Nektony’s official product materials consistently identify it as App Cleaner & Uninstaller for macOS.

Safety overview
Status: Mostly safe
This is a legitimate commercial macOS utility from Nektony, not generally considered malware. It can access and remove app-related files, so mistakes may remove settings or support data for software you still use. Full Disk Access may be requested for deeper scanning, which is normal for this type of cleanup tool but gives it broader visibility into files on the Mac.
Recommendation: Keep it if you actively use it to uninstall applications or review startup items and extensions. If you do not use third-party uninstall tools, it is usually optional and can be removed, but review any detected leftovers carefully before deleting them.
