Definition: APP file
An application in the Mac, also known as an application "package" or "bundle."

IPA Extension for Mobile Apps
Apple's iPhone (iOS) apps may also use the APP package if it was developed for ARM hardware rather than Intel. However, the IPA (IPhone App) extension is the official extension for iOS and iPadOS executables. With the IPA client installed on a Mac with Apple silicon, the Mac can also run IPA applications. See application folder.

Here are some utility apps that come with Macs. For example, Grab.app is a screen capture tool, and Migration Assistant.app copies files to another computer.
Grab.app is actually a Contents folder that contains these files and folders. Right clicking an .app file and selecting Show Package Contents reveals the hierarchy.
