ASL: Learn Sign Language

Learn American Sign Language (ASL) at your own pace: the alphabet, numbers and fingerspelling, with fun games and a camera that checks your signs.

ASL is the sign language used in the United States and most of Canada. Every letter and number comes with a clear hand sign, so you can practice anywhere.

SIGN CAMERA: PRACTICE WITH FEEDBACK
Make a sign in front of your phone's camera and the app tells you if you got it right. Practice each letter on its own, or play Sign Camera and Spell a Word to fingerspell whole words. Recognition runs on your device.

ASL ALPHABET AND NUMBERS
• Every letter (A–Z) and number with its sign
• Swipe through the whole alphabet without leaving the screen
• Letters you already signed with the camera are marked as done
• Search for words and watch them signed in short animations

TURN YOUR MESSAGES INTO SIGNS
Type any message and see it spelled out in ASL. Save it as an image or share it with friends and family.
