No, they are not. Those two are very different in macOS, where the word ‘app’ means an Application Bundle, which is a directory with a .app extension, Info.plist file, a bundle identifier, have an expected directory structure per Apple guidelines, should be installed in /Applications or ~/Applications, and so on and so forth.

CLI tools, including ones that Apple ships or makes, are not apps on macOS.

I’m sorry, this is my pet peeve as well and it’s very frustrating to see this ‘CLI tools are apps’ argument from developers who are not familiar with the Apple guidelines, and then argue about on an ideological basis.
