The problem is larger than you think!

By 2050, over 2.5 billion people will live with hearing loss. Sign language is how millions already communicate, and how millions more want to connect with the people they love.

Problem

Sign Language Learners Deserve Better Tools

Others teach you to recognize signs, not produce them. That’s a problem when sign language is a visual, physical language.

★★★★★
I love this app! it's a very nice app for learning and is a very nice beginning step for learning sign language. Plus the design itself is very appealing! When I first signed in, the app had few downloads, I was even given premium! But now I'm back I'm blown away with how much the UI has improved! The app itself is fun to use and it's very user friendly. So if you're looking for a good app to begin your learning of sign language this app is a wonderful start!

I’m Impressed
I am so happy that someone finally made an app for sign language that is easy, approachable, and fun to use. The turtle is so cute and if you have any friends, family, or even children who are hard of hearing, I would highly recommend this app to them. Even for yourself! I am not personally hard of hearing, but I have friends who are, and this app is a way I can learn to better connect with them.
