Awful ! Dont buy it!
This app is like opening a 3rd year algebra book. Theres all kinds of info, but you dont know what youre looking at. Theres no instructions, no how to, not a single word about the app or how to use it. Just a bunch of Latin names, half the screen black and half the screen blue. I pointed it at Orion but nowhere on my iPhone screen did I see Orion. I pointed it at 2 very bright planets and the screen showed me one planet. Theres only 2 buttons on the screen, one shows you earth when you touch it, the other button goes back to the blue/black screen. Probably a fine app, but without a single word on how to use it its a waste of time (and money).
