iOS (previously named iPhone OS) is an OS for smartphones, made and sold by Apple. It is the mobile OS of the iPhone, the iPod, the iPad, Apple TV and similar devices. At first iOS was called iPhone OS, but it was renamed to iOS in 2010 to show that the operating system was being supported on new Apple devices.
