iOS version history |
iOS (formerly iPhone OS)[8] is a mobile operating system developed by Apple exclusively for its smartphones. It was unveiled in January 2007 for the first-generation iPhone,[9] launched in June 2007.
It is the operating system that powers many of the company's mobile devices, including the iPhone. It was also used on iPads (introduced: January 2010; availability: April 2010) until iPadOS was introduced in 2019, and on the iPod Touch devices, which were discontinued in mid-2022.[10] 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.[11]
As of December 2023[update], Apple's App Store contains more than 3.8 million iOS applications.[12] These mobile apps have collectively been downloaded more than 130 billion times.
iOS is based on macOS. Like macOS, it includes components of the Mach microkernel and FreeBSD.[13][14] It is a Unix-like operating system. Although some parts of iOS are open source under the Apple Public Source License[15] and other licenses,[16] iOS is proprietary software.[17][18]
Major versions of iOS are released annually. The current stable version, iOS 17, was released to the public on September 18, 2023.[19]
