For other uses, see IOS (disambiguation). iOS (formerly iPhone OS) is a mobile operating system created and developed by Apple Inc. exclusively for its hardware. It is the operating system that presently powers many of the company's mobile devices, including the iPhone, iPad, and iPod Touch.
An âAppâ is really a computer program. The operating system on a PC is âWindowsâ. The operating system on a Mac is âMac OS Xâ. The operating system is what you see after you turn on a computer for the first time, but before you install any programs. The OS in iOS stands for Operating System. Thus iOS is the base software that allows all other apps to run on an iPhone, iPod Touch or iPad. Some operating systems include games or utilities. For example Windows comes with Solitaire and iOS devices come with programs to play music and videos.
