It inspires curiosity about the Universe and helps users understand amazing cosmic phenomena.

"For the record, the chairman's favorite iPhone app is Vito Technology's Star Walk a simple astronomy application that harnesses the iPhone's GPS capabilities to present an on-screen view of what stars and constellations should be visible on a clear night from your current location."

"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."
