Although I don't use iOS, someone I know has an iPhone and doesn't want to upgrade his version until he can have a way to revert, preferably with a clone. Are there any recommendations for cloning apps for iOS? A perfunctory Google search turned up several hits, including iMazing. I can't recommend it because I know nothing about it.

Comments? Other ideas?
