Awesome app!

The Arkham City App is made for those achievement hunters and completionist gamers in all of us. As you open the app, you’ll find eight different maps to help you in your quest to find every trophy and riddle in the game. The maps use the pinch-to-zoom feature to focus in and out of the area you are fighting in. Once you find the location, you can click on the riddle and it tells you how to find and beat this particular one. Once you are done, you can push the “item collected” button and the app keeps track of the trophies!
The app can keep track of Batman and Catwoman trophies as well and every riddle solved. You have the option to turn the sound FX and music off, which is nice as if you have the app open all the time, you don’t want to get annoyed by the music and sounds. Sadly, there is no option to make the map bigger and it loses a lot of real estate with a border that I could have lived without. I am sure it looks fine on the iPad, but when you have an iTouch, borders are just a waste.
I strongly recommend getting this app, as it is a nice addition to the guide, especially if you have the Limited Edition guide as it allows you to track the trophies without marking the guide you bought. It also makes it easier to find the trophies and riddles as you progress through the story line. It is a nice companion to the guide and the game. Worth the money.
