Nice App.

It is a nice guide for finding all the riddles you missed and keeping track of your progress. For its price, I wish the App included some of the other optional things the game has, such as the location of all the cameras you can destroy, the Joker balloons you can pop and so on. It would also be nice if it included solutions for the Riddler Rooms.

Another option would be including a code for these map apps inside either the guide or at least in the collectors version of the guide since as it stands, $2.99 is a little too expensive for what the app has.
