For fun, you can set the amount of seconds for your selected sound to play. When you press start, your screen will turn black, so your prankee will not know you have a joker app running. Put your phone somewhere and wait for the sound to go off. Some sounds are soft just to make em wonder what it was, and some will make em jump out of there seat!If you have a sound that you would like to see here, write to the developer or leave a comment. PSA 5 star rating might increase your chances of having your sound included. Hint Hint ; )
