Does the app use true north? It seems it just use magnetic north.

    The app does indeed use true north if you have your location services turned on in the device.  It needs to know your location in order to look up the deviation from magnetic north to true north.

    Even when supposedly using true north, the app occasionally will display incorrect directions.  We have looked at this in great detail and it is actually the device that is giving us wrong data.  The electronic compasses in mobile devices can be notoriously inaccurate at times.

      I have location services turned on. For Sky Safari Pro, it is with « while using the app ».
      Even with this, I always get the message « Unable to determine true north…make sure you have location services enabled ».

      What am I missing?
