Similar to Sky Map, this iPhone 3GS app (needs the compass to function properly) gives you complete knowledge of the night sky.  Though technically you can use it in daylight or in your living room and get the same results. 

While some might not consider it AR (I do, but only tenuously), it does interact with your environment to give you real world information including Wiki access, moon cycles and an object finder.  N0 matter how you might classify the app, it still looks pretty cool.
