Star Guide: Sky Atlas

Star Guide: Sky Atlas is a friendly astronomy companion that turns the night sky into something you can explore, learn, and enjoy — right from your phone.

Have you ever looked up and wondered which constellation you were seeing, or what that bright star is called? Star Guide brings the sky closer. Browse a rich illustrated encyclopedia of constellations, stars, and deep-sky objects, then open the interactive sky map to see how it all fits together overhead.

Tap any constellation to read its story, discover the brightest stars within it, and jump straight to deep-sky treasures like galaxies and nebulae. Every object has its own page with clear, easy-to-read details, and a single tap takes you from the encyclopedia to its exact place on the sky map.

Whether you are a curious beginner, a stargazing hobbyist, or just someone who loves the night sky, Star Guide is a calm, beautiful way to learn the sky at your own pace — no telescope and no internet required.
