The Slide Over feature on an iPad is like having a picture-in-picture capability. While you’re using an app like Safari or browsing through your photos, you can open a mini window that appears in front of the main app you’re using. This is called Slide Over.

Not all apps can be used in Slide Over mode, but some common ones include Spotify, Messages, Mail, Calendar, Notes, and Clock. There are other apps that support Slide Over as well, but those are good ones to start with if you want to try out this feature.

Once you’ve opened a Slide Over window, your iPad will remember the apps you use most frequently in this mode. This makes it easy to swipe between them. For example, if you often use Spotify and the Clock app as Slide Over windows, you can swipe left or right at the bottom edge of the Slide Over window to switch between them. On older iPads, you may need to swipe with a slight arc at the bottom edge.

The simplest way to open a Slide Over window is to drag and drop an app from your Dock. When you’re in an app, slowly slide up from the bottom edge of your screen to access your Dock. Then, tap and hold the app you want and drag it towards the right or left edge of your screen. Be careful not to drag it too far, as that will activate the Split View feature instead of Slide Over.
