How it works

Three small things,
repeated.

A wave hello. A finger to the lips for quiet. A hand that says stop. Most people are already using Key Word Signs without realising it. We build from there.

01 · Start

Natural gestures are the start of Key Word Sign.

Wave Hello. Quiet - Ssshhhh. Stop. Most people are already using some Key Word Signs without realising. We start with what you know, then add to it — sign by sign.

02 · Practise

Reps make it stick.

Theory is step one. Practice is what make signing stick. One small signing challenge a day, building muscle memory until the signs come without thinking.

03 · Crew

Learn with your people.

Learning sign becomes communication when the people around you sign back. Unlock Sign is built for your whole Crew — family, friends, educators, neighbours.

" We are usually all getting the sign a bit wrong. But we almost always know what the other one means.
Signs you didn't know you knew

Five you
already use.

The whole app is built on this premise. Every Key Word Sign you already make with your hands becomes Sign #1 of your voyage.

  • Hello A wave. You're already signing hello a dozen times a day.
  • Quiet A finger to the lips. The most universal sign you know.
  • Stop Flat hand, held up. A whole sentence in one gesture.
  • More Fingertips together, twice. Babies pick this up first.
  • Sleep A hand against the side of the face. You sign this in conversation without thinking.
