If you have a hot rod, or at least you think you have what it takes to be the next John Force, Dynolicious may be the right iPhone application for you. Similar to other performance meters (some that cost hundreds of dollars) Dynolicious is the equivalent of having a radar gun, a drag strip timing mechanism and a dynamometer in the palm of your hand -- all for just $12.99.
At a touch of the screen, you can measure quarter-mile (0.4 kilometer) elapsed times and trap speeds, lateral g-forces, 0-60 mph (0-97 kilometers per hour) times and speeds, braking g-forces and even horsepower (or kilowatts). Dynolicious uses the iPhone's built-in three-axis accelerometers to calculate each parameter to surprising accuracy. Once you enter in your vehicle's information (which includes the weight after factoring in fuel and passengers), the accelerometers inside the iPhone sense vehicle movement and translate it into to real-time data. That data can then be saved for later reference. The Dynolicious application even allows users to edit vehicle settings and enter specific modifications to increase accuracy.
With an average rating of four stars at the Apple App Store, Dynolicious can be purchased for the original iPhone, iPhone 3G, the 3Gs, the iPhone 4 and 4S as well as the iPod touch.
Make no mistake about it; Dynolicious is geared toward those with a need for speed. Of course, HowStuffWorks doesn't encourage speeding or reckless behavior, but anyone curious about the performance of their vehicle will surely get a kick out of putting your skills to the test -- even if it is in the family's minivan.
