This application strives to improve your vehicle's fuel economy by monitoring your acceleration and braking patterns while you drive. Simply enable your GPS, start up the application, and start driving. As you go, the application will give off buzzes to let you know when you are driving too aggressively (one buzz is a bad acceleration, two short buzzes represent that you hit the brakes too hard). The goal is to train you so you drive in a manner that will cut down on fuel usage and save you money. NOTE: This application works only as good as the GPS on your device, so nearby structures can hinder the GPS signal.
