You might not have a smart car, but if you have a smartphone, your car – and you – can be more intelligent about fuel consumption. The greenMeter ($5.99) takes advantage of an iOS device's accelerometer to measure any vehicle's fuel and crude oil consumption, power, and carbon emission. Users enter in a few details about their car, the type of fuel they use, and the weather and the greenMeter is good to go. Drivers can monitor greenMeter and adjust acceleration to get the most mileage out of their tank based on its feedback.
