Sign language is one of the most widespread forms of communication on the planet. Knowing a form of it, such as American Sign Language (ASL), is a useful skill for even those who don’t rely on it. If you have a family member or friend who is deaf or hard of hearing, learning even a few words of sign language can be helpful.

    1. The ASL App

    Best for: Understanding more complex interactions in ASL.


    If you’re looking for a Duolingo-like experience, check out The ASL App. One of the best features is that it often shows two ASL speakers interacting to simulate a true conversation. In each video, you can drag your finger across the screen to control the speed. There’s also a slow-motion option.

    You can even save specific signs to a Favorites folder for quick access. While the app offers a number of different learning modules for free, you can unlock the entire app with an in-app purchase.

    4. Signily

    Signily App Composing

    Best for: Language immersion via the keyboard.

    If you really want to immerse yourself in ASL, a great option is Signily. The add-on keyboard shows you the sign for each letter.

    It’s not the most intuitive way of learning how to sign, since it can rob you of the chance to learn word-specific signs instead of fingerspelling. But the big advantage is that all of the signs are laid out in familiar patterns and go back to regular letters with one touch. Switching between the two should make it easier to memorize the individual letters.

    5. ASL Dictionary

    Best for: All-purpose reference.

    ASL Dictionary is a straightforward and helpful way to learn the language. It has a dictionary of words and phrases that you can sign. When you tap an entry, you’ll see a video clip of the sign in question.

    While it doesn’t teach about grammar or sentence structure, ASL Dictionary does a great job at being a quick and easy reference. There is also a quiz mode that tests you based on the videos.

    As a nice touch, you can view all the content and videos without an internet connection.

    6. Marlee Signs

    Best for: Basic visual learning.

    Academy Award-winning actress Marlee Matlin headlines this app. She signs out the ASL alphabet along with phrases like “Hello,” “Excuse me,” and “I am deaf.” It’s a great choice for anyone starting out who wants to learn the basics from an experienced teacher.

    Matlin signs very slowly, but the app allows you to play the short educational GIFs back even more slowly, which is useful for less-dexterous students and inexperienced beginners.

      Another great app is "Sign ASL". Enter any word and it provides 1 to 10 video clips from many different sources with the sign(s) for the word. Completely free.

      Great post! I thought I might add a new one, released in April 2019 by Play Nice LLC. Hands On ASL is a free app that covers ASL fingerspelling. The app uses 3D models that enable the learner to see the alphabet from all angles. The user interface is playful and even includes some customized skins that make it a fun learning tool. Like some of the other fingerspelling apps, it also includes practice assessments of varying speeds to help the learner master their receptive skills!

      Their app is available on both iOS and Android.

      Brilliant article, Rachel. I used to know A-Z in BSL, but I fell out of the habit; it's something I've been meaning to take up again though, so this might be the motivation I need. I always thought it most useful for anyone in retail: I used to work in a bookshop and was incredibly impressed with one of my colleagues who could sign expertly. Even knowing the basics would make shops more accessible for deaf people.
