About
Sign ASL is a free American Sign Language dictionary for searching words and phrases and comparing signs. Its library contains more than 40,000 video signs contributed by over 150 signers, with access on the web and through Android and iOS apps. Multiple signs for a word can indicate different meanings or regional variation. The mobile apps support searching, comparing, and viewing the videos, and the iOS app adds recent and popular signs, looping playback, navigation among alternatives, favorites with offline viewing, dark mode, and offline startup. No account, registration, login, or personal profile is required by either app. Search terms are sent to Sign ASL servers, where requests are logged anonymously for service improvement. The mobile apps use Google AdMob ads and may process basic device information. Sign ASL says it does not sell personal user data or perform cross-app behavioral tracking. The service is intended for learners, teachers, and the Deaf community.
