Signtone - Audio Check-In
Social Networking
Only for iPhone
Free
iPhone
Signtone is the fastest way to check in to events. No QR codes. No NFC tags. No typing names into forms. Open the app, tap Listen, and the event is identified.
HOW IT WORKS
Event organizers play a short audio signal — a Signtone — through their PA system or speakers. When you tap the Listen button in the app, Signtone identifies the audio signal (similar to how music-recognition apps identify songs) and registers you for the event with one tap.
Works with conference PA systems, laptop speakers, Bluetooth speakers, and even broadcast radio.
