I got my AR version yesterday and tried it out when it got dark. It works, and it is fun that buildings and trees are now showing up in the image with the planetarium image nicely showing up where the sky is supposed to be. But apart from the novelty, what is the use?
I have always identified stars by holding up my iPhone to the sky, and SkySafari has shown an image that made it possible to identify the visible stars, but of course without buildings. The iPhone camera is not able to see any stars at all, so adjustments is only possible if the Moon is visible, or perhaps Venus. The Sun can also be used, but again, apart from novelty, I do not see the advantage of superimposing the starry sky on the daylight sky.
Have I missed a possible advantage of AR versus old-fashioned compass mode?
