Apple replaced Google Maps, formerly the default mapping app on iOS, with its own navigation software in September when it released its latest mobile platform, iOS 6. It is reported that the fall-out happened when Google refused Apple access to its voice-directed turn-by-turn navigation and vector graphics.
The instant success of the new Google Maps, which became the most-downloaded free app just hours after its release, again indicates the unpopularity of Apple's own mapping software, which immediately came under fire for its widespread inaccuracy.
The new Google Maps iOS has received good reviews for its updated features such as "more maps on screen" as well as "rotating of 2D and 3D views".
The New York Times described the app as "free, fast and fantastic," saying that "Google Maps for iPhone is an astonishingly powerful, accurate, beautiful tool".
