What is Sign ASL?
Sign ASL is an education app that helps learners look up American Sign Language words and phrases and watch sign videos on their device. It is built around a searchable ASL video dictionary, making it useful for students, families, teachers, interpreters, and anyone who wants quick reference access while studying or practicing. Common use cases include checking how a word is signed, comparing sign variations, and reviewing vocabulary during lessons or everyday conversations. The app is available through Apple platforms, including Mac with Apple silicon support through the App Store listing, and it is also promoted through the Sign ASL website. Its main value is fast, portable access to a large collection of ASL sign videos in a simple reference format.

Safety overview
Status: Mostly safe
Sign ASL is a normal reference app for learning and looking up ASL signs. The App Store listing says its privacy practices may include identifiers and usage data for tracking and advertising, so privacy-conscious users may want to review those settings before using it regularly. No unusual system-level access is expected for its basic dictionary purpose. If you keep it installed, use the privacy options available on your device in the same way you would for other ad-supported educational apps.
Recommendation: Keep Sign ASL if you use it to study or reference ASL vocabulary. Remove it only if you no longer need the dictionary, and remember that uninstalling the app will also remove its local app data from your Mac unless that data is synced elsewhere.
