Car making mysterious noises? There's an app for that

You may pride yourself on your ability to diagnose a developing engine problem by sound alone, and then replicate said mystery sound, Click-and-Clack-style, to amuse/annoy your friends and coworkers. ClingClanger is a new phone app that's designed for the rest of the world -- those who can't identify piston slap by sound and are startled by the clicking caused by a dying battery. The natural impulse is to simply crank up the radio and hope the noise/problem goes away.
