Star Walk for iPhone is an amazing star gazing app that allows you to turn your iPhone into a digital planetarium. You can use the app as simply a reference app or as an interactive app as you're star gazing. For iPhone 4 and iPhone 3GS users you can use the built-in compass function to make the app even more interactive.

When you launch Star Walk you'll be asked if you'd like to allow the app to use your current location. Clicking yes will allow the live view feature to locate you and show you the part of the sky that is viewable to you.

iPhone 4 and iPhone 3GS users can take this a step further. Simply point your iPhone in the direction you'd like the app to tell you more about. The app will also track any movements you make and change live view to reflect the part of the sky you are navigating to. This app is perfect for amateurs as well as professionals. I would have loved this app when I took an astronomy course in college (I probably would have paid a lot more attention). I'd highly recommend this app to any college or high school student taking an astronomy class.

The app also has a nice daily info page that will show a ton of information pertaining to your individual location including sunrise, sunset, length of the day, and moon phases. The app also shows information pertaining to other planets including sunrise, sunset, and the angles at which you'll need to look from the horizon to see certain bodies (alt/az coordinates).

When it comes to the search feature, you've got tons of choices. Not only can you search constellations but you can search other bodies in the solar system, deep space objects, individual stars, and satellites. If an object is not visible from your location or at that particular time of day or year, it will be grayed out.

My absolute favorite feature of this app is the live view. It's simply gorgeous and extremely intuitive. You can view the simulation or choose an option that utilizes the camera to show your actual sky with star charts over it so you can interact with the real sky.

iPad and iPod touch users are not left out. Star Walk also offers a gorgeous iPad version as well. You can use location based features while you are in wifi. When you're not, you still have access to a beautifully put together reference app as well.

If you're in the market for an awesome astronomy reference app, this is hands down the one you want. These are just some of the features that make this app great. And it gets better!
