Rev It Up! let's you pretend your iPhone or iPod is actually a motorcycle grip, so that as you rotate your wrist in a revving motion, you hear actual motorcycle engine revving. Sounds heard are real motorcycle engine sounds cleanly and clearly recorded from actual motorcycles. Choose from nine different motorcycles to see the actual grips and hear their actual sounds.
Features the following sounds for each of the included motorcycles: starting and stopping the engine, revving, and the continuous spectrum ranging from idle to full throttle.
Update for 64 bit devices and Retina display.
