2015 PC Magazine Editor's Choice! Luminos is the award-winning, all-in-one astronomy app that goes beyond simple stargazing.

Luminos combines millions of celestial objects into a beautifully-rendered space simulation that will amaze you. Our enthusiastic customers range from hobbyists to professional astronomers, and everyone in between. And now, Luminos features the largest catalog available on mobile, with more than 113 million stars!

Whether you want to admire ancient constellations, watch satellites soaring overhead, find out what that brilliant dot is on the horizon, or recreate eclipses, Luminos has what you need.
Browse the largest deep space image catalog of any mobile app, anywhere, or track 3D meteor showers now or from the past. Travel through time, identify craters on the moon, fly through space, watch the solar system in motion from high above, or see the multitudes of asteroids orbiting perilously close to our planet. Hold Luminos up against the sky and it will effortlessly guide you to find any star or planet.

You can even get live sky charts and satellite alerts on your Apple Watch! Luminos makes it all easy and fun.

Instead of buying many apps to get all of these features, Luminos includes everything in one low price. There are no in-app purchases to nibble away at your wallet and there's no advertising to distract you from views of the heavens.

When you're ready to go even further, Luminos will be ready with you. If you're fortunate enough to have a computer-controllable telescope, then Luminos can command it for you to find objects quickly and easily. Detailed data on every object is easily available within Luminos, even without an Internet connection. Powerful planning tools help you make the most of your evenings by showing you exactly what will be visible tonight or any night in the future.

Get out there and start exploring!
