Is there an app to tell you what an "app" is? Or what's an app store? There is now!

Here's a fun fact: there's a program that allows you to use the camera on your cell phone to take a picture of the barcode on a product. The phone then accesses the internet, searches for that exact same product elsewhere - for a cheaper price- and notifies you in seconds where to get and the address of the store. Pretty cool app, isn't it?

An "app"? What the...
When you hear someone talk about an "app", they're really talking about an application- a software application. An app is really no more than a micro-sized software program usually designed for a smart phone (iPhone, Android, Blackberry, etc.) that performs one highly specific function like providing restaurant reviews, a fun game or something more practical like an appointment reminder. They cost everywhere from zero (free, free, free!) to hundreds of dollars, although the majority are less than $20.

So, where can you find these wonders of technology and how do you buy some? The guys over at wisegeek.com will explain it all. Turns out, buying and installing an app is straightforward and quickly done, although you must be careful- collecting apps can be habit forming!
