Signtone - Audio Check-In

Signtone Admin

About this app

Signtone is the fastest way to check in to events. No QR codes. No NFC tags. No typing your name into a form. Just walk in, hear the sound, and tap to register.

HOW IT WORKS
Event organizers play a short audio signal — a Signtone — through any speaker at their venue. Your phone listens for it. When detected, you receive a notification with the event details and can register with a single tap.

Works with conference PA systems, laptop speakers, Bluetooth speakers, and even broadcast radio.

TWO AUDIO MODES
Universal: Ultrasonic signal (16.5-17.5 kHz) — inaudible to most people. Perfect for conferences where silence matters.
Broadcast: Audible signal (1.2-3.8 kHz) — works over radio, PA systems, and noisy environments.

PRIVACY FIRST
- Audio is processed on-device to detect Signtones only
- We never record conversations or background audio
- You control which profile to share at each event
- Microphone access can be revoked anytime
