A PRACTICAL SETUP
Share one number across your displays
Choose what the number means for your activity. Assign one operator and check every display.
Agree what the number means
Explain the numbering system and when the value changes. Use a clear title if needed.
Choose a controller and invite the group
Create a session on the device that will lead. Participants join in the app using the QR code or 6-digit session ID. Add an optional joining password if needed, then check the connection with a test number change.
Make the number comfortable to read
Adjust the in-app text size from 80 to 500 px. Choose text and background colours or try the four display presets. Check the display from the actual viewing distance rather than judging it only close up.
Keep the session flexible
Use + and − to update the number. Pause and resume the session; use optional sounds to signal changes.
03 / Better together
Made for moments

A little more
clarity.
Does the app issue numbers automatically?
No. An operator selects the number. SendNumber displays it on connected devices.
Can I choose what the number represents?
Yes. Explain its meaning to your group or visitors and choose a useful title.
What is synced between devices?
One device controls the number; connected displays show it in real time.
How do participants join a session?
They scan the session’s QR code or enter its 6-digit session ID in the app. If you set an optional password, they will need it to join.
How can I customise the display?
Set the text size from 80 to 500 px and choose custom text and background colours. Pick Classic, Minimal, Card or Fullscreen styles, or use the Chalkboard, Whiteboard, Night Mode and High Contrast presets.
Can number changes make a sound?
Yes. You can enable optional sound alerts for number changes in the app.
Is this demo a real session?
No. This demo illustrates the idea locally in your browser. Use the SendNumber app for sessions with connected devices. The display is a simplified illustration, not an app screenshot.
