The home screen is where your apps live and where you can launch them. Only 20 apps will fit on one home screen, but you can organize your apps in multiple home screens (up to 11). (The apps in the Dock stay the same no matter what home screen you’re on.) Above the Dock are several dots signifying the number of home screens you have; the currently selected one is highlighted in white. Swipe left or right to go from screen to screen.
