iOS 18 hidden apps are findable, if you know where to look
iOS 18 includes a new feature where you can choose to require Face ID to open an app, or go one step further and hide it from your device altogether. This second option removes the icon from the home screen, and places the app in a specially obscured Hidden folder in the App Library.
Biometrics are normally required to even see the contents of this hidden folder, before you can access one of the apps hidden inside it. However, now that iOS 18 has been released to the world, users are discovering ways to find out which apps have been hidden, with no Face ID required.
