Ratings and Reviews


crashes on purchase

This app is ok and looks good, and the upgrade to premium is reasonably priced (2.99). However after purchasing the upgrade it will not run. Crashes, and when I attempt to start it back up again, I get a burp box that says it is damaged and I need to uninstall it and install it again. Did that, restored my purchase, and the same thing happened all over again. Sent the crash report to Apple, so please fix this. Thank you

Update: Although this Lite version will not work as it is, I was able to install the full version without being charged for it, so now I have full use of the app. It is really good and I recommend it. Just know that there are issues and I hope the devs will take care of all this stuff pretty soon.


Really Good App

This app is beautiful. The colors light up the screen. You can not tell, I could not anyway, that this app was a lite. I has many amazing features and I would highly recommend it to anyone. Like it knows where you are in the world and it can do the stars and constellations for that area. It also has the moon patterns, descriptions of all the planets, names of zillions of stars, a world map that shows day and night areas on the earth at the moment and so much more. Great app to download.


Pretty good

This is a pretty good app with great graphics if you are looking to tour the solar system and look at the constellations. When you are looking at the star map, it is so helpful in finding out constellations and their projected path. The only complaint is that I wish it were easier to navigate when in the solar system map. Other than that, it works great, no glitches so far.
