'Arookoo: World Explorers' steps up social gaming, but stumbles on Facebook

Arookoo is a "social fitness platform" in three parts: mobile, web, and social. Reader's Digest Association and Vivity Labs' big idea is to turn walking into a real-life game. To do this, they released a free iPhone app that takes advantage of the iPhone's Accelerometer and GPS functions, created a website to help users track fitness progress, and finally, a Facebook game that players can earn boosts for, while walking around with their iPhones in the real world.
