The Green Gas Saver is a remarkable application that lets you monitor your fuel efficiency and warns you if you are driving too fast or turning too hard. Two on screen gauges display how a user accelerates and corners, as warning LEDS, and tones train a driver to eliminate bad habits.

This neat little application also keeps a running score so you can see how well you are driving in real time and over the course of a trip. Try to improve upon your score and save gas. After a few weeks of using Green Gas Saver, you will actually reteach yourself to drive efficiently, and you will see your fuel costs drop!
