It was introduced along with the iPhone in 2007.
It is the operating system that powers many of the company's mobile devices, including the iPhone and iPod Touch; the term also included the versions running on iPads until the name iPadOS was introduced with version 13 in 2019.
It is the world's second-most widely installed mobile operating system, after Android.
It is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS.
