Great app. You can really get an idea of the time and position of the planets and stars. I like the earth's transparency which allows you to anticipate when something will come into view. I want them to make time of day marks on the sky so I can put the view ahead to an event I've learned about. They do have lines but there is 16 lines of longitude not 24- each is worth 1 1/2 hours. Sun rises in the east, 12 hours of horizon and you can guess. You can adjust the date and I guess I can change Greenwich Mean Time to plus or minus. Anyway this app helps.

Excellent app, informative and easy to use. I only wish that the Android version had all the features described in the video. BTW, for the users complaining with variations of "location is way off": recalibrating your phone's compass should fix that.

I miss the old version of the app where it was more toned down, and navigated the sky with fingers rather than moving the whole phone. Yes, there is that manual option, but it's very sensitive.

What's new

Titlebar hidden on devices with a dedicated menu button. Fixed problem that inappropriately disabled automatic orientation on some devices. Automatic orientation requires compass, gyroscope, and accelerometer sensors.
