ASL American Sign Language
Very simple free app with all of the 26 letters of the alphabet – just the ABC flashcards, nothing else.
This free app contains 100 ASL words and signs. Nothing fancy.
This is the ASL app to get, it’s US$2.99 and contains around 5000 words. It’s got all the basics and the alphabet and common words, plus the really tricky multi-use words. Recommend.
Baby Sign Language Dictionary
This app is $US5.00 and has 300 ASL signs – which is really more than enough for a baby. In fact, adults will learn something from this app too. 🙂 Research shows that babies who learn signs do way better in school and in life as adults.
Baby Sign and Learn Lite
If you have the misfortune of getting this dud of an app, at least get the free version. Mostly audio, more effort spent on cute animated videos then on content. Thumbs down.
