Jumpy little thing!

I downloaded this app to help my daughter with her 5th grade astronomy class. Weve spent almost an hour calibrating and then trying to recalibrate the app because every time we open it, all of the compass settings are off significantly. I can be viewing the "moon" in the app and have the actual moon at my back. If I move two inches one way or another, lo and behold, theres the moon (in the app) again! Please please fix this! I consider myself fairly handy with an iPhone but I cant make this app function properly.
