It's cool for a short period. If you need to find planets, stars, moons, or constellations than it's great. But I get these notifications and I think I'm gonna see something extraordinary by it telling me a location. In stead it just pulls up the sky map. And my phone is usually pointing down when reading messages. Soooo you can imagine how that doesn't help

This app is amazing. I have never seen such an in depth star and planet app. They provide unique notifications that update you on so many events happening in space. I love how you can turn with your phone and it shows exactly what your camera is facing. The creators of this app definitely had the right idea. Thank you for this amazing free app!!!

I love this app! I took one star away because the orientation of the objects in the sky isn't right & I have to reset or recalibrate the thingy in my phone that makes the compass point in the right direction. Other than that, I love this app! My granddaughter thinks it's awesome & loves the planets on the map. We also love that when there's some celestial event & it's cloudy, we can still see it in the app.
