Apps

If you’re unable to find an App on your device, you can use the Search function to find it.

To search your iPad, simply touch the screen in any free space except near any of the screen edges, and slide your finger downwards to reveal the Search dialogue. Enter the App name - and if installed, the icon and its location will be displayed; touch the App icon and it will launch.

If installed Apps have actually gone missing, you can reset your Home Screens:

Settings > General > Reset > Reset Home Screen Layout

Have you looked at another screen? If you see more than one dot on the bottom of your screen swipe right or left to get to the next screen.
