Rev, Torque, Carbonga
A lot of Car Talk listeners are excited about these apps, and for good reason. They actually make available data from your car's computer that was previously accessible only to mechanics with expensive scan tools. Rev for iPhone, Torque for Android and Carbonga, also for iPhone, all display the basics of engine performance like speed, RPMs, and fuel consumption. Connected to your car's OBD port, these apps talk to your car's engine, enabling you to diagnose problems and clear warning lights. If you've ever found yourself opening your wallet to the tune of $95 just to turn off your check engine light, or wanting to perform a quick check on a used car, you'll understand why we're interested to see these apps on the market ... though, of course, they're lousy news for mechanics looking to save up for that next boat payment.
