iOS 6 Maps
 

Apple has built its own Maps service into iOS 6. Apple did all of the cartography for the maps and the app now supports turn by turn navigation. Siri integration is present as well. All transitions are extremely smooth, the app overall looks very well built.

Apple integrated Yelp reviews for local businesses into its new Maps application. Apple's Flyover integrates high resolution 3D imagery with the new Maps application, similar to what Google and Microsoft have done with their own mapping services.
