Save gas, save your wallet, and save the world! EPA studies have shown you can save the equivalent of $1.50 per gallon by using your gas and breaks more gently. This Android app helps you pull it off! Place the phone in a car dock or on your dash and start driving! It will show you when you are accelerating too quick, or breaking or turning too abruptly to save the most money. By default, the app expects the screen to point at the back of the car and halfway up toward the sky, 45 degrees. You can calibrate it in the options, however. Check out the settings to customize the app exactly to what you need.
