for questions involving communication with or data migration between Android and (Apple) iOS devices (usually iPhones/iPads). Please note that questions not involving Android are off topic.
iOS is Apple's mobile version of the OS X operating system used on Apple computers. iOS is derived from OS X, with which it shares the Darwin foundation, and is therefore a Unix operating system.
Originally released in 2007 for the iPhone and iPod Touch, it has been extended to support other Apple devices such as the iPad and Apple TV. Unlike Microsoft's Windows Phone (Windows CE) and Google's Android, Apple does not license iOS for installation on non-Apple hardware.
