Cosmodial Sky Atlas

About this app

Stargaze the real night sky, live. Cosmodial is a free star map and planetarium that shows what's actually above you right now. Tell it where you are, or let it use your location, and it draws the sky for your exact spot and the current time, so what's on screen matches what you'd see if you looked up.

Ever glanced up and wondered whether that bright dot is a planet or just a star? Cosmodial can tell you. Tap anything to see what it is, how far away it is, and where it sits in the sky.

Drag to look around. Zoom out for the whole sky, or zoom all the way in until Saturn's rings and Jupiter's moons come into view, roughly what you'd get through a telescope. Hold your phone up and point it at the sky, and the view follows where you aim.

What's in it:

• Over 101,000 stars, each in its real color and brightness
• The Sun, Moon, and planets, plus 16 planetary moons, all at true scale and fully textured
• Galaxies, nebulae, star clusters, famous comets, and the interstellar objects that have passed through
• Solar and lunar eclipses you can jump to and watch play out
• Live tracking of the ISS and Tiangong as they pass over you, with a heads up when tonight has a good flyover
• Constellations drawn with clear, labeled figures
• A time control to run the sky forward or back, from minutes to centuries
• Search for anything by name and fly straight to it
• Favorites, to save the objects you like and come back to them
• A red night mode that keeps your eyes adjusted to the dark

It runs completely offline once loaded, so you can take it out to a dark field with no signal and the whole star catalog is still there. No account to make, no ads, and no tracking of any kind. Your location stays on your device and never gets sent anywhere.

It's free. Point it at the sky and see what's up there.
