A new feature for iPad users with iOS 9 is the ability to view two apps at once on the screen. You can use the Slide Over feature to bring an app up on the right side of the screen while pausing the main app. You can use the Split View feature to have two apps take up half of the screen each and interact with both. You can use the Picture In Picture feature to keep video on the screen while switching to other apps. These new features only work on the latest iPad models.
