I have yet to find an app that has worked as hard at this one at being comprehensive and incorporating so many different sign languages. It was a HUGE help when interacting with the Deaf in Europe. Maybe should add a warning that you only get the dictionary for free. It seems a lot of reviews were upset about that. I think it's 100% worth the $5 for the full version. If not they also have a great website. Thanks so much for developing this!

Fantastic app. It's extremely well done. The languages are extensive, the ability to slow the signs is amazing, and we haven't found a word not there yet! It would have gotten five stars, but, it's a bit buggy on the baby sign portion. It's supposed to scroll thrhough pictures and show signs as you tap, but a quick scroll down confuses the index and the app locks.

Fantastic app, has regional signs, great because you can choose the sign Language for you. This is useful when I'm interpreting between sign languages or talking to Deaf from different countries as it allows me to type the word and choose the sign language. One of a kind, I always recommend this app!
