There are many ways to hide iPhone apps. You can move the apps to a distant Home screen page and place them in a folder.  You can restrict their use or simply delete them using iTunes.

Reorganizing Apps

  1. Drag the icon of the app you want to hide to the right edge of the screen. Doing so will separate this app from other apps and drop it on a new Home screen tab. You can keep repeating this step to place the app farther away from your main page. The 11th Home screen page is the farthest you can go.
  2. Similarly, drag other apps to the same Home Screen page. Then, group them all in a folder.  by Drag one app over another to create a folder, then rename the folder e.g. “Miscellaneous.” You can drag up to 12 apps into a folder.

  1. Open “Settings”, “General” and “Restrictions.” Tap on the”Enable Restrictions” tab and enter your four-digit passcode when asked to do so.
