In some ways, the food truck is the closest thing we have to hunting wild game in an urban setting. It's food, but it moves. How are you supposed to find food that moves? With the NomNom Finder app, which has just arrived on Android.
This service tracks food truck nearby in real time. The map view is good for getting the lay of the land – to plan your hunt of the wily food truck. There is also a slide-out nav bar with food trucks listed by distance. Each truck can be marked as a favorite for easier tracking later, and there are links to call or visit the truck's website.
It doesn't have trucks listed for all areas just yet. The closest one to me is roughly 900 miles away, so I think I'll go with some non-mobile food today. Feel free to give it a shot, though.
