SpreadTheSign is a multilingual sign language dictionary built around video lookup. It offers more than 600,000 sign videos across 23 sign languages, including ASL and BSL. Users can search for words and sentence examples, compare how a word is expressed in different languages, and slow videos to follow signing movements. Favorites let users save signs, while hand alphabets and fingerspelling provide additional reference tools. Baby signs are included as well. The dictionary is available on the web and as Android and iOS apps. The maker describes it as a reference for sign language learners, families, educators, interpreters, and people who need to look up a sign quickly. New words, videos, and language coverage are added regularly, though available content can vary by language. Google Play lists the developer-provided data safety disclosure as no data collected and no data shared with third parties. The iOS app is listed as free with in-app purchases, including a Pro Version.
