What is it?

Buzzer.mobi turns your phone into an Internet-connected gameshow buzzer.

To host a game, click the "Create game" button. You'll be given a Game ID to share with your contestants.

Contentants then enter the Game ID along with their nickname to join.

When a player buzzes in, they will freeze out everyone else's buttons. Admins can freeze the buzzed player (unfreezing everyone else), or reset everyone's buzzers.

Buzzer.mobi features latency correction, so users on slow connections are not negatively impacted.
