Billed as "the exciting new life-affirming app that helps pizza get to your mouth," Pizza Compass has been called "the most important app ever made. Ever." (Note: not an actual quote from a reputable reviewer.)
Pizza Compass is a simple app that shows you a slice of pizza that points with its tapered end to the nearest pizza place. The pizza slice steams when you get closer to a pizza joint, and it links with Foursquare to help you find them.
I'll let Zeus do the talking:
Pizza Compass was made by pizza enthusiasts Zeus Gorham Munkist and Dan Blackman at Oak Studios.
