Buzz In!

This app will transform your phone or tablet into a game show-style wireless buzzer lockout system. It operates over both WiFi AND Bluetooth! Just select one device as the Controller, and all other devices as Buzzers, and you're ready to go. A working WiFi router is required for WiFi mode, but if you're on-the-go, use the Bluetooth option. Complete with a flashing screen and audible tone when you buzz in, it will even display your name on everyone else's device when you've buzzed in! The device chosen as the Controller can then clear the system, ready for the next question.
