Star Walk is a handy astronomy guide that shows celestial objects (stars, constellations, satellites, etc.) in the exact positions on the sky above you, providing information about them. It helps you find your way across the sky, determine where to look for any chosen object, rewind or fast-forward time to see how celestial bodies move.

How do you use the Star Walk app?

All you have to do is point your phone at the night sky, and Star Walk locates and pinpoints the exact location of the celestial object you want to see. You can use the precise location to find the object in your telescope. You can access information about every celestial body that shows up in the app. It also includes a calendar of upcoming celestial events so you can plan your next stargaze.

The first time you open the app, an overview quickly explains how to use Sky Guide’s gestures and time controls, but it’s all quite straightforward: pinch to zoom, drag to scroll, and tap to select. Flick and subtle inertia has the sky continue moving for a moment, in an elegant manner.

Aesthetically, the app is a delight. The night sky is bathed in light above a mountainous silhouette horizon, beneath which everything takes on a darker hue; delicate illustrative artwork outlines constellations when they’re approached. An ambient soundtrack plays, and stars emit noises — hotter and larger stars, respectively, offering higher and louder notes.

Is Star Walk free?

Star Walk is free for all iOS and Android devices.

What are the benefits of Star Walk app?

Star Walk's maps also move as you turn around, but they offer a lot more detail - making it more daunting for beginners but more useful once you know your way around the night sky. It includes extra information on stars, galaxies and nebulas, along with the real-time position of dwarf planets, comets, asteroids and man-made satellites.
Star Walk also makes it easier to plan your astronomical adventures in advance. You can check rise and set times in the future, fast-forward and rewind through the night and see extra details such as the phases of the moon.

What is the difference between Star Walk and Star Walk 2?

The original Star Walk remains one of the best apps for budding stargazers of all levels, but Star Walk 2 has added some excellent features for night-time jaunts. It will identify the location of stars, planets, meteors and nebulae, the International Space Station and comets. Point it at the sky and you’ll soon be marvelling at the cosmos.

Star Walk Widgets

A stargazing widget tells you about the upcoming visible celestial events with respect to user's location, current phase of the moon, time of sunset and sunrise, and even alerts to the closest iridium flares. It helps you be aware of the upcoming events and have the info at your fingertips. By tapping the event on the widget you can open up Star Walk, go to Calendar section and set a reminder for the event in the Calendar app.

Iridium flares are the reflections of sunlight caught by Iridium communication satellites orbiting the Earth. They happen as the satellite turns to a specific angle to the Sun and the viewer on the ground and these position can be calculated allowing Star Walk users to see the flares. The Star Walk HD widget will inform you on the coming Iridium flares that can be seen from your location.

Duran Duran's keyboard Nick Rhodes mentions Star Walk as his favorite app:

"With the Star Walk app, if you hold your iPod up towards the sky, you can see all the stars and constellations. It even tells you the names of all the planets. Then, if you point it towards the ground, it shows you what all the stars are in the other hemisphere. It’s brilliant, and if you’re ever somewhere with a clear sky and no light pollution, it’s a revelation. It’s beautifully designed and makes clever use of the available technology. I’m fascinated by astronomy, but even if you’re not, give this a go."
