Rip off
First of all, this version is prone to crashing. All the time.
Secondly, if you want to do anything other than “look” at stars from your location at the current time, you have to pay an additional fee. So if you want to say, look at the stars from the surface of Mars in 2456 BC, that will cost you. Want a larger star catalog? That will cost you. My advice to to go buy some other app that shows the Starry Night.
