Star Walk

If you are an astronomy geek than you have already probably used your iPhone to look up planet positions and star charts. Star Walk is a handy app that will do just that using your GPS coordinates. But its easy-to-use interface makes it fun for anyone who simply wants to know what constellation they are looking at. Just run it and hold it up to the sky and it is easy to learn a little something.
