Born in a moment of whimsy, Game Show Sounds provides you with 2 buttons ... representing a right answer (green) and a wrong answer (red). Press the right answer button to hear a "ding"; the wrong answer button gives you a "buzz". Press repeatedly and quickly to make your point!
Originally, this was created for use in our software development meetings, as a goofy way to say "wrong answer!" or "exactly right!" (yes, developers are usually dorks), but now that we have it running on our phones, we find more and more uses for it every day.
Sounds are configurable, with 12 of each type to choose from. Press the "i" button.
