Good app, many useful features

The app works well on my iPhone 6. There are many good planetarium apps but this is my favorite so far. Each feature works well. The display updates fast with no lag as I move the iPhone. The azimuth (compass bearing) is more accurate than in other apps running on the same iPhone. I like seeing the sky at other wavelengths. I like the augmented reality mode, in which the camera view is superimposed on the display and updated about once per second. Best used in twilight because the iPhone camera is not very sensitive
