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.

Nick Rhodes, The Daily Mail

It’s jam-packed with imagery and data on the 200,000 stars and planets in its database, and has a calendar so you can keep track of interesting celestial events. I particularly like the beautiful imagery it uses to show constellations and detail on the planets.

Kit Eaton, The New York Times

There's not much to not like about this app. This is one of the best science apps you can buy.

Chris Crowell, Mashable

This app brings the old paper star chart into the smartphone age, and makes exploring the night sky easily accessible to everyone.
