The app, which is the first from the Crown Publishing Group, uses the iPhone's rear camera (there's no support for the iPhone 4's front-facing camera at this time) to "scan" the face of any would-be zombie to illustrate their infection rate.
The app is free and it's a great idea, but the execution is a little flawed. For instance, you can't adjust the zombie scan overlay after you've snapped an image (for better placement of eyes and nose, etc.), and you can't load in pre-existing photographs.
That means that unless you are able to get someone's face into the exact position of the scanner, the effect doesn't work very well.
Nevertheless, we like that you can share your photos via e-mail or post them to Facebook. And we have to give props to Crown Publishing for using an iPhone app as a way to promote one of its books.
Are any of your friends or family members zombies in disguise? Let us know.
