About this app

Unlock Sign builds your confidence to Sign. Build a daily habit of Key Word Sign — the Auslan-based signing system used alongside speech to support communication.

Learning the theory is just step 1. Using the signs with your crew is where it gets hard - and fun!

It's designed for anyone building a Signing community around someone they love. A new-parent learning to sign with their baby. A grandparent who wants to keep up. A teacher wanting to unlock communication with a non-verbal student. A sibling, a neighbour, a support worker. The whole Crew, learning together.

WHY UNLOCK SIGN

Most people already use everyday gestures that are official Key Word Signs without realising it. A wave hello. A finger to your lips to shush for quiet. A hand rocking a baby. Unlock Sign starts there — building confidence first — and turns signing into a daily habit that grows around you - and your crew.

Learning the signs is only the first step. Using them every day, with your people, is what makes the language stick. The app is built for that habit.

HOW IT WORKS

Practice an extra Sign each day.
Watch your confidence grow as your build your muscle memory. The habit, not the theory, is the point.

Bring your people in. Captains create a Crew, invite family and friends, and learn together. Everyone earns points. Everyone celebrates milestones. The Crew wins.
