Apple iOS

Apple's mobile operating system for its iPhoneiPad, iPod touch, Apple TV and similar devices. Apple iOS was originally called the iPhone OS but was renamed in 2010 to reflect the operating system’s evolving support for additional Apple devices.

Apple iOS is currently in v9.x release, with iOS 9 first being unveiled in 2015 in conjunction with the release of the iPhone 6S and iPhone 6S Plus smartphones.

Features and Enhancements in Newer Releases of Apple iOS

Recent versions of iOS have introduced a number of powerful new features to the mobile OS, most notably Apple's Siri advanced voice recognition application, "Proactive," a contextual, predictive personal assistant that's tied in with Siri to deliver personalized information based on a user's preferences, habits and location, a built-in instant messaging client (iMessage), integrated support for Apple's iCloud personal cloud storage service, iTunes Radio, and AirDrop support.

Support for Older Devices

Older devices such as the original iPhone and iPod touch are not supported in the iOS 4, iOS 5, iOS 6 and iOS 7 family of updates, and the iPhone 3G and second-generation iPod Touch cannot be updated past iOS version 4.2.1.

The primary competitors to Apple iOS in the mobile operating system space are Windows Phone 7, Google’s Android OS, and the BlackBerry OS.  Apple iOS does have a head start in the apps department, with its App Store already featuring more than 500,000 third-party applications.
