Is it a star or the planet Mars? Knowing what’s up in your night sky is easier than ever. Sky Guide’s AR mode superimposes figures onto your real sky so visualizing the heavens becomes effortless. Have you ever wished you could recognize constellations but didn’t want to fumble around with paper star charts? Now you can.

A speck of light crosses the night sky, growing brighter. What could it be? You don’t have to wonder anymore. Track a bright satellite and receive perfectly-timed notifications whenever the International Space Station is about to fly over your location. With Sky Guide, you’ll be saying ‘Goodbye, aliens’ and ‘Hellooooo, astronauts!’

Voyage to the past or future with cinematic time controls. Know where the Moon will be later in the evening so you can capture that perfect photo or be an eyewitness to history’s greatest comets.

Whether you’re searching for Sagittarius, Saturn, or the next big meteor shower, Sky Guide is jam-packed with information and rich graphics that will satisfy the most curious minds. Plus, stay current with location-filtered events like solar and lunar eclipses with Sky Guide’s personalized Calendar.
