Apple Inc. invented iPadOS as a mobile operating system for their iPad tablet computers. It's a rebranded version of iOS, Apple's iPhone operating system, renamed to highlight the differences between the two product lines, particularly the iPad's multitasking capabilities and keyboard support. At Apple's 2019 Worldwide Developers Conference (WWDC), it was unveiled as iPadOS 13, indicating its status as the iPad's successor to iOS 12. On September 24, 2019, iPadOS was made available to public users.
