In November 2016, Google announced the discontinuation of Google Map Maker as of March 2017. Mobile app Google Maps is available as a mobile app for the Android and iOS mobile operating systems. The Android app was first released in September 2008, though the GPS-localization feature had been in testing on cellphones since 2007. Up until iOS 6, the built-in maps application on the iOS operating system was powered by Google Maps. However, with the announcement of iOS 6 in June 2012, Apple announced that they had created their own Apple Maps mapping service, which officially replaced Google Maps when iOS 6 was released on September 19, 2012.

In August 2017, Google Maps for Android was updated with new functionality to actively help the user in finding parking lots and garages close to a destination.
