Useful but needs work


This is helpful. But some things I wish they would add or upgrade are: 1. ability to slow down all signs, 2. Videos aren't loading, 3. Remove the splash page asking you to continue then add your contact details before accessing the sign of the day, 4. More realistic words and phrases. Chances are I'm not going to sign many of these phrases they provided, 5. Add alternate side view for complex signs. 6. Mark or alert users on app which words are newly added after a dictionary refresh. If that can't be done then perhaps add a date to the dictionary line item of when the sign was added to the app

Theres just one thing..


I think it's a good way to learn asl especially when you're first starting out but the one thing I think the app should have is a description under the video explaining the differences between a word that is the same but has two or more signs. For example like under clothing there's two different signs for boot so it should have a description explaining when you should use it.

My one complaint....


This app is good and the real reason I wanted an ASL app was to help keep me knowledgeable over summer break. My only issue with this app is that every region has a different dialect of the language so for example the way the app shows Hawaii is not how I learned it. How I was though Hawaii is signed is like pretty but with an H instead of the whole hand. No one is wrong in the sign they use for the word because the language is always changing but that is kinda a flaw with this app.
