SendNumber: Live Number Sync

Sync a live page number across connected devices.

SendNumber lets one device control the current page number while other connected devices display the same number in real time. Keep a shared reference visible during classes, courses, presentations, workshops, training sessions, and group reading.

START A SESSION
Create a session in seconds and share its QR code with your group. Participants can join by scanning the code or entering a 6-digit session ID.

CONTROL ONE LIVE NUMBER
Use simple + and - controls to change the current page number. Connected display devices update when the number changes, so everyone can follow the same reference.
