The iPhone maps application introduced in September 2012 with version 6 of the operating system (iOS 6). Replacing Google Maps, which was featured on all iPhones prior to iOS 6, Apple Maps includes turn-by-turn directions, real-time traffic information and interactive "Flyover" 3D views of metropolitan areas. Not What Users Expected Apple's map data is not as extensive as the data in Google Maps, which combined with erroneous results reported by many users caused Apple CEO Tim Cook to publicly apologize for the app replacement and even suggest users download third-party mapping apps until Apple Maps is improved. In December, Google Maps became available as a free download in the Apple App Store. See iOS versions.
