The row of apps at the bottom of the iPhone or iPad Home screen is called the dock. Apple has placed some popular apps in the dock for quick and easy access. If there are other apps you would rather have in the dock, it is easy to change the apps to suit your needs. Many people prefer to put their most frequently used apps in the dock.
To move an app to or from the dock, tap and hold any app on the Home screen. All the apps will begin to “wiggle.” This is an editing mode that allows you to rearrange the apps by dragging them around onscreen. While the apps are wiggling, you can drag apps on and off the dock.
The iPhone dock can hold a maximum of four apps and the iPad dock can hold up to six. If the dock is full and you want to move a new app into the dock, you will first need to move an app out of the dock.
Remove an App From the Dock
Tap and hold your finger on any app until all the apps start to wiggle. Once the apps are wiggling, you can remove an app from the dock by simply dragging the app out of the dock and placing it anywhere on the Home screen.
Add an App to the Dock
While the apps are still wiggling, you can add an app or a folder to the dock by dragging the app or folder from the Home screen to the dock.
Some apps have a small “X” in the top left corner of the icon. Tapping the X will delete the app.
When you are finished moving apps, press the Home button to exit the edit mode. This will cause the apps to stop wiggling.
