A Trusted Stargazing App

I have been using this app for years, and it has only been getting better. Keep up the good work!

Not what I was really wanting

The app it's self is cool a lot of information and interesting to read... But I have yet to find an app like you can find on google play store. This app does not allow you to point your phone to the sky and it tells you what is where in the sky you are seeing. This app simply uses your compass to spin an already existing picture with the stars... Very disappointed with this

The app is crap!

Oh it's worse than just half a screen! The last update wiped out most of the app's features. I can't find anything. Looks like they're selling me back the features that used to be part of the app. I call foul. This used to be a very good and educational app. Now the app is crap!

Possible glitch

Installed the latest update, only get half a screen when in landscape...

Good app for Basic+ Stargazing

Easy to use with many different features and a good astronomical catalogue (350,000 objects). I haven't needed to try any other apps because this works more than well enough on both iPhone and iPad.
