Like Google have done to their search app, by having a native app allows Google to make more revenue off their application on the ios. Also keep in mind that Google has a much larger database of stores/locations/bus routes than iOS so they have an edge in usability that will take years for apple to catch up. As long as apple does not ax it from the app store, sounds like a good business plan.
