SpreadTheSign review
A free-to-start video dictionary for comparing 23 sign languages.
Reviewed by iTechGuides Editors · Editorial team · Updated Nov 2026
SpreadTheSign is a multilingual sign-language dictionary for learners, families, educators, interpreters, and anyone who needs a sign reference. Available on the web, iOS, and Android, it supports ASL, BSL, and 21 more sign languages. Its core experience centers on video lookup, with searches for words and sentence examples alongside hand alphabets, fingerspelling, and baby signs. The app listing reports more than 600,000 sign videos across 23 sign languages, giving the product a broad reference focus rather than a single-language curriculum.
The strongest reason to choose SpreadTheSign is its comparison and lookup format. Users can compare signs across languages, slow video playback, and save signs as favorites. That combination suits people working across language communities or checking how a concept differs between sign languages. The multilingual sign-video dictionary also makes it useful for educators, interpreters, families, and learners who need visual examples. It is better suited to reference and exploration than to a linear study plan, since learning and progress features are limited.
SpreadTheSign follows a freemium model. The Free plan provides access to the app with in-app purchases, while the Pro Version adds premium app features. The product is therefore easy to start with for buyers who want to assess its dictionary coverage before paying. Choose it for multilingual search, cross-language comparison, and video-based reference across web and mobile platforms. Choose an alternative if your priority is a structured course with deeper lesson sequencing, ongoing progress tracking, or a more focused path through one sign language.
