Ok app

I like the app so far, but the person showing the sign language is in a black background, kind of depressive! Also the whole presentation is kind of blurry!

Incomplete

It doesn’t have words like car or pretzel. The signs are often different from what I learned in ASL class in college. I deleted this app. It’s easier to just google the word I want.

Use at work all the time!

This app helps me fill in the many large gaps in my ASL vocabulary. I use it almost daily with young children who receive speech/language services and their parents. I’ve referred many parents and other professionals to the app, as well!

Great Easy App!

Easy to use would give a 5* if included popular phrases, but as a newly deaf person it has helped me more than I could say!

This is a good app (has great potential)

This is a great app. I cannot deny that. I would do 5 stars, but the quality of the video is very hard to see. It lags and skips. They are at a 480p.

The signs need to redone (no, they are not incorrect) they just need to be at a higher quality.

And more common phrases Such as:
What’s up?
What’s new?
I am learning ASL for you.
Long time no see.
That’s very kind of you.
I dare you.
Your portion for today is $$$
You owe me $$$
I am a slow learner.
Please help me.
I need your help.
Please follow me.

Any thoughts?
Any idea?
Anything hurting?
The doctor is asking ...
Do you like me?
Do you love me?

Other than that. They are good.
