Buzzer

Finally, a buzzer for the iPhone! This app turns you and your friends' iPhones and iPod touches into game buzzers! Start up one device as the game Host, and add as many iPhones and iPod touches to the mix to have your own trivia party!
Each device becomes a buzzer and everyone will see who buzzed in first! Forget spending $20-$220 on expensive buzzer systems, just download the app from the App Store and start your own ad-hoc trivia games wherever you have a wireless network!
Version 2.0 allows for multiple choice questions and free response answers to be submitted!
Expandable to any number of buzzers. Requires one iPhone or iPod touch per buzzer.

NOTE: This application requires at least 3 devices on the same wireless network with the app installed. If multiple devices use the same iTunes account, this is supported and only one purchase is required!
