User reviews

Keep update getting better

This app is very helpful for people preparing to go to Japan and meet deaf people. I can see the developer worked very hard creating so many sign pictures. Well done!

Nice app

I want learn signdict because I want talk with more people and I think signdict help me a lot to learn !

Recommend this app!

I learn ASL to communicate with my son who are deaf. It easy to learn!

Remote work

I enjoy learning sign language and this app has allowed me to learn with great results!!

20,000 signs and no search

This app is fantastic, don’t let the title fool you. It has not crashed on me and the pictures are on the better end of signing infographics. The signs are organized by kana for quick access. I personally happened to get this monster spiral bound book called American Sign Language Hymns For Singing(I found it at Cokesbury) which called for a lot of looking up specific signs. I opened up this app thinking, maybe this awesome app will make this easier… nope.

Response from developer

Hello! I'm so happy to hear that you're enjoying the app, thank you for the kind words and detailed feedback! 😊 Updated Edited: Search Tab Bar is now available on V1.2.0 and later! Oh, I think I know what you mean! Try scrolling down, just like in the Apple Settings app, the search bar should appear on top when you scroll down. It’s a little hidden at first, but it should pop up and help you find specific signs much more easily. Hope that helps! Thanks again for your support! 🙌
