This morning Universal has updated their iOS and Android app with a new look and features.
The app has all the basic features you'd expect. Wait times, ride information, restroom locations, shopping and dining information. All great stuff. Another great feature is GPS. You can set a way point to an attraction or other point of interest and get walking directions with pictures of landmarks to help you get a sense of where you are.
Universal also promises updates down the road including customizable itineraries and instant Express Pass purchase. The last one being specifically interesting. Art for Diagon Alley is already in the app but information on attractions are not available just yet.
