When the Nintendo Wii first hit the scene, it was billed as a way to get kids (and some parents) off the couch. But when zombies are afoot, people actually run for their lives. That's the idea behind Zombies, Run!, a clever game for joggers that describes activities of fictional flesh-eaters, the only escape from which is to physically run away. Voice prompts indicate the runner's actual mileage along the way and encourage runners to speed up when biters draw near. For Android and iOS, $3.99. A free companion website (shown) joins runner communities, tracks routes and plots "escape" paths.
