Gachi Buzzer: Fair Quiz Game

Turn every iPhone or iPad into a real quiz buzzer. Gachi Buzzer lets the host and players use the same app. Connect everyone to the same Wi-Fi, choose a role, and start. No account, special hardware, or internet connection is required for play. FAIR, TIMESTAMP-BASED RESULTS Each device records the instant it is pressed. Results are ranked using synchronized press times rather than the order network packets arrive, so a small network delay does not decide the winner. Close finishes can be shown as ties, and every round can be reviewed in milliseconds. BUILT FOR THE HOST See every player and sync status, arm each question, mark answers correct or incorrect, keep score, play sound effects, and move smoothly to the next round. QUICK SETUP WITH QR Scan the QR code issued by the host to connect to the host-side Wi-Fi (Personal Hotspot). Once connected, the app finds the quiz room on the network automatically — if several rooms exist, just pick one. When venue Wi-Fi blocks communication between devices, or no Wi-Fi is available, one person's iPhone Personal Hotspot can create the local network. DUO PLAY Split one device into two face-to-face buzzers. Try 50 two-player rounds in total across One-device quiz show and Duo Play before buying; unlock continued Duo Play with a one-time in-app purchase on the shared device. All standard one-player buzzer, judging, scoring, and sound features remain free. Ideal for quiz nights, classrooms, parties, clubs, rehearsals, and events.
