Want to learn some words in American Sign Language? This easy-to-use, clean designed app does a nice job of teaching signs through very short video clips of kids doing the signs. The app also includes a “game” option where users are shown a video clip of a sign in action, given three images and asked to choose which image the sign represents. The app includes 21 free signs plus 50 more available as an in-app purchase and the developer promises “more to come!”
