.app Extract

On macOS, ".app" extensions are used for application bundles. They are basically just a folder with a ".app" extension. Unfortunately, iOS doesn't allow you to browse them. This Shortcut will take the contents and put them all into an archive.

Use the share sheet on a file with ".app" extension to use this Shortcut.

The archive output by this Shortcut needs to be extracted with an app other than Shortcuts. An error occurs during extraction through Shortcuts and the archive does not fully expand its contents. I use Documents by Readdle and it works like a charm.
