Game Buzzer: Quiz Host

Turn one iPhone or iPad into a quiz buzzer system. Players scan a QR code and buzz in from their browser — fair to the millisecond. Perfect for classrooms and parties!

Game Buzzer turns your iPhone or iPad into a quiz buzzer system. Players don't need to download anything — they join the same Wi-Fi, scan a QR code and buzz in from their phone's browser.

HOW IT WORKS

1. Tap "Create Game"
2. Players scan the QR code (or type the address) and enter their name
3. Approve players and tap "Open Buzzer"
4. Players hit the big BUZZ button — you instantly see who was first

FAIR TO THE MILLISECOND • Measures each device's network delay and clock offset, and ranks buzzes by corrected time • Shows everyone's buzz order and reaction time in milliseconds

SCORING & GAME FLOW • One tap to score Correct or Wrong, with customisable default points • After a wrong answer, reopen the buzzer for a steal • Question progress (Question X of Y), buzz history and manual score edits • Scores can be visible to everyone, own score only, or hidden

POWER CARDS • Double Points, Hint and 50/50 — or create your own cards • Give cards to specific players, who use them from their own phone

HOST TOOLS • New players must be approved, so strangers can't join • Host Web Console: run the game from a computer or second device (protected by a password QR code) • Players who disconnect rejoin automatically with their score and cards • Your room is restored if the app closes unexpectedly

NO SERVER, NO SIGN-UP Everything stays on your local Wi-Fi between your device and the players. No account needed.

Available in English, Traditional Chinese and Simplified Chinese.

Note: Keep the host device in the app (in the foreground) while playing. Switching away briefly (about 30 seconds) is fine. The host and players must be on the same Wi-Fi network (or connected to the host's Personal Hotspot).
