So you've already got a sweet ride... now you can measure just how sweet it is. Dynolicious uses the iPhone's built-in accelerometer to measure you vehicle's 0-60 acceleration, quarter mile elapsed time, horsepower, lateral G's, and several other performance metrics. A history of test results for your car are saved, so averages and trends can instantly be retrieved. Dynolicious also allows you to record modifications made to your car, and to evaluate the resulting gains (or losses) in power and performance.

Dynolicious has been track-tested at a major dragstrip against regulation timing equipment, and has demonstrated accuracy comparable to standalone performance meters which cost hundreds of dollars.

Dynolicious has support for both US and International units of measurement, including MPH or km/h speeds, lb or kg weights, and HP or kW power figures.

Post your results to Facebook and Twitter to impress your friends!

Whether you're a serious tuner or a casual enthusiast, you'll find the feature-rich and easy-to-use Dynolicious is both a valuable tool and fun car toy.

Dynolicious is intended for experienced drivers in a suitable location. Always obey traffic laws.
