Is it a star or the planet Mars? Knowing what's up in your night sky is now effortless with Sky Guide. Hold your iPhone or iPad up and Sky Guide automatically aligns itself to the stars above you—no setup required.

Have you ever wished you could recognize the constellations but didn't want to study those paper star charts? Sky Guide's augmented reality (AR) mode makes learning your way around the sky clear and effortless.

Whether you're in search of the constellation Virgo, the Andromeda Galaxy or the next big meteor shower, Sky Guide is jam-packed with information and rich graphics that will satisfy the most curious minds.

Voyage to the past and future with cinematic time controls. Know where the Moon will be later in the evening so you can capture that perfect photo. See what the sky looked like the moment you were born or be an eyewitness to history's greatest comets.

It's a star! It's a plane! No, it's a satellite! Sky Guide features hundreds of bright satellites for you to identify and track. You can also receive notifications whenever the International Space Station flies over your location.

Use Sky Guide anywhere—on your evening dog walk, camping trips or in the classroom. The app works with or without Wi-Fi, cellular service or GPS, so everything is at your fingertips no matter where you go.

- Huge stellar catalog: 2.5 million stars!

- Filter: X-ray the sky and explore invisible wonders.

- Red night mode: Preserve your dark-adapted eyesight.

- Notification Center Widget: At-a-glance essentials including rise and set times for the Sun, Moon and planets.

- Apple Watch: Sky Guide can send you a notification when an event is about to happen in the skies above your location, like when the International Space Station is due to fly over. You can also keep tabs on the latest solar activity or add our super-accurate Moon Complication to your Apple Watch face.

They have made some updates recently that make it significantly better now including night mode which is waaaaaayyyy better on my eyes so i dont go blind at night. Woohoo! Also the gps and orientation stuff is significantly improved since i downloaded it. Also the satellite info is super awesome!! All in all this app has a ton of features and yet they set it up to customize what you want to see. Thank you for making this app!
