Aggravate Nails On Chalkboard

Aggravate is a take off on popular noise making applications like Sound Grenade. This simple app gives the user the opportunity to annoy those around them by producing the universally repulsive sound of nails scratching a chalkboard. Use it to not-so-subtly let the person next to know that they are being too loud and that their presence is reminiscent of one of the worlds most hideous sounds. To make the sound, simply drag your fingers down the face of the chalkboard. Be careful, turn it up too loud and you might really annoy the people around you, not to mention yourself. The sound of nails on a chalkboard has been scientifically proven to be one of the most horrific sounds known to man. Psychologically destroy anyone you (temporarily) care to with this fun little device.
