Android users in Los Angeles, San Diego, San Francisco, New York City, or Washington DC can find food trucks with the app TruxMap Lite, from Los Angeles developer Frank Pardo. (This free app is also available for iOS.) Pardo aggregates tweets about current and future food truck appearances and puts them on a map. The information is also available on the TruxMap website: http://www.foodtrucksmap.com. This large map carries more information than the apps do. It covers 38 cities in the United States and Canada.
