Ever since the first iPad launched, its run the same iOS as the iPhone. That's changing this year, though, with the launch of iPadOS.

iPadOS is a more powerful version of Apple's mobile operating system for a more powerful device. Starting with the home screen, iPadOS has a new layout that'll let you see more apps on a single page. You can also add your Today View to your iPadOS home screen, letting you permanently keep your widgets in view.

Another improvement of iPadOS is the ability to run multiple instances of the same app side-by-side. This means that with Split View, you can do something like have two versions of the Notes app running right next to each other. And then App Exposé will let you get a quick view of all the running instances of one app at once.

The Files app is getting improved in iPadOS, too. A new Column View will give you another way to navigate your directories with high-res image previews, and iCloud Drive is getting folder sharing. And in another big update, iPadOS will support USB drives, SD cards, and the ability to log into an SMB file server.

Rounding out iPadOS are improvements to Apple Pencil, like a redesigned toolkit and a latency reduction from 20ms to 9ms; improved text editing and a three-finger swipe to undo; custom fonts support; desktop-class browsing in Safari that'll automatically serve you the desktop version of a site and optimize it for touch; 30 new keyboard shortcuts for Safari; and many of the improvements of iOS 13, including Dark Mode and performance improvements.

iPadOS is available in a developer preview form today and will launch to the public this fall. It'll be available to iPad Air 2 and later, all iPad Pro models, iPad 5th generation and later, and iPad mini 4 and later.
