iOS is the mobile operating system used by Apple’s iPhones. First introduced with the original iPhone in 2007, the software has remained a feature of every iPhone released in the years since, and continues to provide the basis for other Apple operating systems including iPadOS, tvOS and watchOS.
Apple's App Store serves as the centerpiece of its iOS mobile operating system, with the company’s virtual marketplace now containing more than 2 million apps optimized for the platform.
New versions of iOS are released annually – typically ahead of new iPhone launches – with iOS 17 expected to replace iOS 16 in September 2023.
