Incredible app


I have had this app. For about four years and although I have tried others I continue to go back to this one. They let you know when something visually coming up to see, like meteor showers are able to view and the graphics are awesome. For anyone interested in looking up, I say get this one, you won't be sorry.

I love this app. We are full time RV and love to see the stars at nite. With this app we know just what we are looking at as we move around the country and the sky changes above us. With the calendar we can see when the ISS or planets will be in our view along with comets or meteor showers. I also love the red light at nite with the sky view. Too cool!

Amazing guide, info at right time

What a great teaching and learning tool. Now I can really look at somethings with my telescope. The live sky while holding my iPad upside down matches looking up like a window into what your seeing, moving direction, up, down, even what you might see (or just missed) just over the horizon.
