Google Maps <ref>Google, Inc. "Google Maps for Android." Accessed August 1, 2012 from http://www.google.com/mobile/maps/</ref> contains a transit trip planner, which is available for several devices including Android mobile phones, iPhones prior to iOS6, and Blackberries. Features vary by mobile platform. Currently, Google Maps for Mobile seems to be focus primarily on Android, although other platforms such as Windows Mobile and Java Micro Edition have been supported in the past. New iPhones with iOS6 will not have Google Maps or transit navigation features (see the “Transit App for iOS6 and Beyond” section below) <ref>Emily Badget. (2012).

Google Maps for mobile supports location-positioning on all devices that offer GPS features. Google Maps for Android devices offers the most complete feature-set, including a “Transit Navigation” feature that notifies transit passengers when they need to make transfers and alight from the vehicle for their destination.
