iOS 7 is the seventh major update for Apple's iOS mobile operating system that runs on portable Apple devices like the iPhone, iPad and iPod Touch. Apple's iOS 7 debuted in September 2013 in conjunction with the release of the iPhone 5S and iPhone 5C smartphones.
Apple iOS7 features a completely redesigned interface for the mobile OS that delivers a more streamlined and flatter (i.e. less 3D) design, making for what many consider a more modern look. Many of the core iOS apps have also been redesigned and enhanced in iOS 7, including Safari, Weather, Camera and Photos, iMessage, Notification Center and more.
iOS 7 additionally introduces new functionality like a Control Center that provides quick access to common settings like Wi-Fi, Bluetooth and Airplane Mode; true, smart multi-tasking (apps now have the ability to fully work in the background); automatic app updating; improved Siri capabilities; iTunes Radio; iOS in the Car support; and Apple's AirDrop file sharing protocol for sharing photos, contacts and other information with iPhone users that are in close proximity.
