Star Walk Review: A Sky Map in Your Pocket

One of my favorite things to do on a clear sunny day is look up at the stars at night. It is amazing how many stars and even planets you can see. It makes it even more fun if you have a booklet telling you what stars and/or planets will be visible on specific nights. But, wouldn’t it be even nicer if you didn’t have to bring one of those booklets around with you (which are hard to read in the dark by the way). With Star Walk, this dream becomes a reality.

Star Walk shows you all its information based on the time of day and your location. Using Apple’s location services, you must only allow it to find your current location, and everything else is automatic. If you would like to change the time of day you’re looking at, simply click on the Clock icon (in the upper-right corner) and you can change it. To navigate around the map, you just use pinching and dragging. There are even four markers for North, East, South and West so you know exactly where to look for a specific constellation. There is also a red line for the horizon making it, again, even easier to see where something is.

Star Walk is cool enough with just the ability to look around a virtual map. But, it also adds some other features. When you press on a constellation name (in the virtual sky), you will see a white drawing of it with the stars. This feature is great for showing to kids (and for helping one find the constellation). While the name is still selected, if you hit the “i” button, you will get more information. A “W” button will also appear allowing you to see a Wikipedia article on it.

Constellations are not the only things Star Walk knows. If you click on any star or planet on the screen, you can also hit the “i” button and get more information.

What I would say is one of the most important features that Star Walk carries is its search. If you hit the search button (lower-left corner), you can search for stars, constellations, planets and messier. If the object is visible to you, its name will be in white, if not, they name will be grayed out. When you click on one, it will take you there on the map. This makes it so easy to find what you want.

Star Walk also includes some nice preferences. The first one is night mode, which basically turns everything into a red-ish color. There is also the ability to turn of the pictures of constellations and sounds. And finally, you can adjust the brightness of stars, planets, etc. All of these can be accessed from the button in the lower-right corner.

Star Walk costs $4.99 in the App Store and is the International Year of Astronomy 2009’s official product. It is extremely intuitive and also provides many features for amateurs and even pros. Anyone who likes watching the stars (and has an iPhone or iPod Touch) needs this app.
