Play a great practical joke on your friends with this app. Start the app, put it near a door or window, then sit back and wait. After a 60 second delay, to give you time to set it up and leave the room, a sequence of sounds will begin. These include scraping, scratching, tapping, knocking, growling, footsteps, and other various sounds designed to have your buddies freaking out, wondering what kind of evil creature is trying to get in.

The hardest part will be playing along and trying not to laugh. Great for entertainment at company parties, casual get togethers, or anywhere else. Especially fun when watching a horror movie, late at night.
