## What is SignBridge?

Bridging the gap between people who sign and those who want to understand them.

In an emergency, every second counts. SignBridge helps a person who signs to be understood: point the camera, and the recognised LSF signs appear as a sentence, read aloud.

OFFLINE. NO ACCOUNT. FREE.

HOW IT WORKS
• Open the app and point the camera at the person signing.
• They make a sign, with hands and upper body in the frame. A framing guide helps them get in place.
• The sentence appears on screen and can be read aloud.

SIGNS FOR THE MOMENTS THAT MATTER
Saying hello, asking for a doctor, showing where it hurts, calling the fire department: the signs were chosen for situations where people need to understand each other fast. The full list opens from the main screen.

EVERYTHING STAYS ON YOUR DEVICE
All images stay on your iPhone or iPad. SignBridge works with no network, even at the back of a shop or high in the mountains.

FACE TO FACE WITH IPHONE DUO
The outer display guides the person signing into position, then shows them the recognised word, so they can check they were understood.

A TOOL, NOT AN INTERPRETER
SignBridge recognises a short list of LSF signs. It does not understand LSF in general, it can get signs wrong, and it does not replace an interpreter. The list will grow over time.

Available in French and English.
