Very helpful in learning ASL vocabulary

This app has been an important tool to help me learn ASL over the last 7 years. It doesn’t have all the signs I want, but as I don’t have fluent ASL speakers around very often, it is a good source for new signs and to help me remember some I once knew. I’m a Dad with 2 deaf children who have cochlear implants. They are mostly oral and in mainstream school, but we want to be bilingual as much as possible. This app is a key tool.

Not many signs

I am a DHH long term substitute teacher for who is not fluent in ASL. I know, I know, but the district was desperate and I know enough to teach kiddos who are very young and don’t have much language since their parents don’t sign. Anyway, this app has been pretty much useless since about 90% of the time there isn’t the sign I need on here. Thank goodness for my aide who is hard of hearing and is fluent in ASL, but I feel bad always having to ask him. Also, I have an awesome paper dictionary but it takes longer to look up words and the drawings aren’t always easy to understand. If you added more signs, this would be an awesome app since the signers are very easy to understand.

Developer Response ,

We try to have every ASL Sign, not every English word has a sign in ASL. The English language has over 1 million words, whereas ASL only has about 5000 Signs. ASL is not a form of manually coded English. If you find a sign you feel is missing please email it to us and we will add it the next time we film.
We worked hard to make this app which has helped a lot of people communicate, we hope you reconsider this review. Thank you

Love it!

Yes I love it, and it is very easy to use. It has lots of words which are easy to find alphabetically. Because I am deaf on one side and heard of hearing in the other, I am learning ASL. The ASL Dictionary is very useful and I highly recommend it especially for ASL learners.

It is now two years later and I still love this app.
