Completely Broken This app used to work now the calibration is way off shows the horizon from bottom left corner to top right corner. Shows the moon to the North  have calibrated  reset  uninstalled and reinstalled all with the same bad results. Basically this app is useless as it is nothing on the screen is where it is in the sky. Do not bother with this as there are many more that do work. Even after turning off the gyro things are still wrong the Map shows the moon almost straight up it is 8pm.
