AppDelete isn[SQ]t a single, universally known application. The name "AppDelete" is generic and could refer to several things :

*

A generic term:

It[SQ]s simply a descriptive term for the *action* of deleting an application. Many people might use the phrase "AppDelete" informally to refer to the process of uninstalling software.

*

A specific app (uncommon):

There might be obscure or niche apps with the name "AppDelete," particularly on less popular app stores or operating systems. These would be very specific to their platform and purpose.

*

A custom script or program:

Someone might have created a personal script or program they call "AppDelete" to automate the uninstallation of apps, potentially with additional features like cleaning up leftover files.

Without more context (e.g., the operating system, where you encountered the term, any further description), it[SQ]s impossible to say definitively what "AppDelete" refers to.
