This is a utility app that helps the user locate E85-carrying gas stations. It also features a calculator for gasoline-ethanol comparison and some interesting facts about ethanol. It is available for download in the app store for $0.99.
It was first released in 2010 and continues to be updated every couple of months. If you have any feedback about the app or any suggestions for additional functionality, please feel free to comment. Plans are in the works to add a link to bring up a google map with directions and a search option.
