I don't own an iPhone, and I'm generally revolted by the sheer number of idiotic Apps that are out there (though the lightsaber one is pretty cool).  But if this one works the way they claim, it might just be incredibly kick-ass.

Basically,  you load the app on your phone and hit the stupidmarket.  When you find an item you're interested in, you use the iPhone's camera to take a picture of the barcode.  The application will then translate all the gobbledy-gook that passes for an ingredient list and rates the product compared to other comparable items, tells you the calories per serving, gives you the item's traffic light rating (Green = good, Yellow = so so, Red = not so good), lists information that the food company may not want you to know, and then offers healthier alternatives.  

I know that many of you, like me, don't buy much that actually comes in a package.  But you've got to admit that in the quest to be an educated, healthful consumer this type of application is pretty damned neat.  And a heck of a lot faster than using your phone to Google the things you're unsure of ;)

In particular, I think that an app like this will be most eye-opening when applied toward "health" or "sport" foods, like protein bars, supplement drinks, etc...
