Prior to iOS 18, there was no official way to hide apps on iPhone or iPad; you had to stick one inside a folder to keep it out of view. To hide an app, long-press it on your device's Home screen and choose Require Face ID. Choosing Require Face ID keeps the icon where it is while requiring authentication every time you open it. Alternatively, pick Hide and Require Face ID to remove it from your Home screen and searches. To unhide something later, long-press on it in the Hidden folder, choose Don't Require Face ID, and the app will return to the top of the list after it verifies you.
