Star Walk is an incredible astronomy app for iPhone and iPad: a mobile planetarium that puts the galaxy at your fingertips.

Just point your iPhone or iPad device at the sky and it uses GPS to identify the constellations in real time. The app offers a huge volume of detail while allowing you to pan and zoom around the galaxy.

Perhaps the most interesting features allows you to see how the sky looked at any point over the last two years, taking in events such as solar eclipses and meteor showers.

It’s a beautifully-designed, innovative and hugely educational app that thoroughly deserves its place on the App of the Year shortlist.
