Apple created and developed a new mobile operating system iPadOS for its iPad line of tablets. It was announced at 2019 WWDC. A derivation from the iOS but with great emphasis on multitasking. On 24th September 2019, it was released.
Initially, iPhone and iPad had the same features but over time, the iPad was seen as a medium to incorporate a growing set of features that are not available on the iPhone such as the ability to run multiple apps simultaneously.
With more and more additional exclusive features being added, the iOS on the iPad became more and more distinct from the iOS on the iPhone.
A successor to iOS 12, iPadOS began with version number 13.1. There was no 13.0 release for iPadOS. Currently, 13.3.1 is the latest version.
Now the icon grid displays up to five rows and six columns of apps regardless of the orientation the iPad is in.
Widgets can now be added on the first screen from the apps for easy access.
Spotlight search is no more a part of the widgets but can still be accessed by swiping down from the center of the home screen or pressing Command + Space if a keyboard is connected.
iPadOS has a multitasking system that is developed with more capabilities as compared to iOS.
With features like Slide Over and Split View, it is now possible to use multiple different apps simultaneously.
Double-clicking the Home button or swiping up from the bottom of the screen and pausing will display all currently active spaces. Each space can feature a single app, or a Split View featuring two apps.
Swiping up slightly from the bottom of the screen will bring up the Dock while an is being used. The dock contains apps that can be dragged to different areas of the current space. It can be opened in either Split View or Slide Over.
Dragging an app to the left or right side of the screen will create a Split View, which will allow both apps to be used side-by-side.
The viewing size of the two apps in Split View can be adjusted by dragging a pill-shaped icon in the center of the vertical divider and dragging the divider all the way to one side of the screen closes the respective app.
Slide Over can be created if an app is dragged from the dock over the current app. Slide Over can be dragged to either the left or right side of the screen. It can also be hidden by swiping it off the right side of the screen and swiping left from the right edge of the screen will restore it.
Users can now have several instances of a single app open at once. It is possible because of a new Expose mode.
With a picture-in-picture window, it is possible to watch YouTube videos while using another app. In this mode, the videos can be shrunk down in a picture-in-picture window. This window can be resized by pinching and spreading and can be docked to any of the corners of the screen.
In iPadOS, the Safari browser now shows desktop versions of websites by default.
It also includes a download manager.
There are 30 new keyboard shortcuts if an external keyboard is connected.
iPad can now be used to function as a second monitor for MacBook or iMac running with macOS.
With Sidecar, the Apple Pencil can be used to simulate a graphics tablet for apps like Photoshop.
iPadOS allows external storage, such as USB flash drives, portable hard drives, and solid-state drives to be connected to an iPad via the Files app.
iPad Pro (3rd generation) connects over USB-C but the Lightning camera connection kit also works to connect external drives with previous iPads.
iPadOS supports all devices with Apple A8 / A8X chip or later. Devices with 1GB of RAM including iPad Air, iPad Mini 2, and iPad Mini 3 are not supported. Following are the devices supported by iPadOS 13:
