I LOVE this app! I’m 61 and have always loved watching and reading about space and the universe, like Carl Sagan, etc. It’s really great getting push messages about upcoming events, and also pointing my iPad up at the sky and it knowing where the stars and satellites are and naming them. This was the first app I ever bought when I purchase my first iPad and it is well worth the few dollars. I’ve enjoyed it for years. And oh yea, I can’t forget the great background music, you’ll feel like your at the science center viewing the stars!

One of my favorite apps

I forget when I installed this app on my iPad but after I moved out of the city to a place where I could really see the stars it's become my most used app. I've learned to recognize constellations, observe satellites, notice various asteroid showers, and best of all, track the Milky Way across the night sky. I've even taken up night photography to capture some of the magic myself. I keep the music off so I don't wake anyone. I love this app! Heavenly.

Every minute on this app is EXCITING!!!

You're going to love it.
The adjustments are phenomenal!
There's a slide bar to adjust the density of all the stars to see. What that means is you get to blow your mind of all the stars there are mapped, (omg!!!) or you can thin out the ones further away and see what's right in front of you for less confusion...But there's nothing confusing about this app! There's another slide bar for the time clock you can free wheel and see satellites and stars move in their as is orbits. Truly a visual to be seen!!
Day or night, see how to navigate...
There's extra info on stars and satellites when you touch click them.
Get your kids on this app ASAP!
Thank you to all the developers as many times as there are stars, I love this app.
