Most telescope mounts have to be moved to their home position after any power outage or reset, then aligned from there. In some cases plate solve can avoid this but whole-sky search often fails. A solution could exist in skysafari pro. Let the user define a place to put a phone on the mount or telescope, either using a phone holder or just a place they can reliably hold the phone. With the telescope home, they would first calibrate to record the orientation of this holding place. Then, any time later, they could ask skysafari to (after the phone stabilizes for a bit) get the orientation of the phone, compare it to the come calibrated orientation, and set an approximate location in the mount, which can be used with plate solve or to make other things easier.
Unlike skysafari compass mode, it probably would not use the compass, as that has error and and for a roughly north pointed mount, accelerometers are enough. The most likely location of a phone holder would probably be the phone lying on the telescope or its handle or dovetail bar, the same as if the phone were lying flat in the saddle. As such the top of the phone would be pointed in the direction desired, not the back (rear camera) as is the case when using SS in compass mode. But really, you can let the user calibrate it in any handy position. If a user happened to put the phone on the scope such that its camera can see the sky, there is the alternate option of capturing that view and plate solving it, for a more accurate reading that could even be good enough to align with, but that's an extra credit problem.
