If you’re looking for the best sign language apps in 2023, this article is here to help.

With language-learning apps becoming more popular and refined in recent years, it’s no surprise that learning American Sign Language online is becoming more accessible than ever.

But, there’s a range of factors to bear in mind when choosing a sign language learning app, such as instructors’ credentials, how comprehensive the content is, and who it’s aimed for.

You’ll also want to consider how much coverage the app gives overall – is it focused on fingerspelling or still images? Or does it include video content to help with expression?

With all this in mind, we’ve pulled together the best ASL apps out there to help you decide what’s best for you.

In this article, we’ve considered different types of teaching styles as well as each app’s focus — whether it be on fingerspelling, reading American Sign Language, or basic letters. We’ve also taken into account other aspects like price, value for money, and skill level.

So, let’s get started!

What is the best sign language learning app?

In sum, these are our picks for the 10 best speed reading classes:

  1. Preply
  2. italki
  3. Lingvano
  4. ASL Study
  5. Ace ASL
  6. The ASL App
  7. ASL Kids
  8. Pocket Sign
  9. MarleeSigns
  10. SignSchool

Our top recommendation is Preply. This is because the app matches you with an instructor who can provide 1-1 tutoring in sign language. With Preply, you can find tutors that match both your needs and your schedule. This means you’re able to get the most for your money by committing to times that fit around your busy lifestyle.

As most ASL tutors will tell you, apps or book-based learning are rarely sufficient on their own. In fact, they’re best used as a supplement to more “real-life” learning where you express and interpret American Sign Language with another person. So, Preply is not only a way to commit to learning – it’s also the best method to get you reading and expressing confidently in sign language.

Preply offers discounted trial lessons so you can try out different tutors for fit. You also have access to the free Preply blog and Q&A section, which helps you to cement your learning and connect with others. Unlike other apps, Preply also allows for real-time feedback. This means that any mistakes can be addressed early on and your teacher can help to get your learning on track.

Also, if you’re not satisfied with your lesson, you can request a full refund or a free replacement.

Alternatives to Preply’s ASL tutoring include italki, which also uses a 1-1 teaching model or Lingvano, which focuses more on independent, yet interactive, learning.

Overall: This course really stands out with its Sign-recognition technology. That being said, a lot of the course content is premium-access, meaning you have to pay to unlock most lessons. Overall, this is an innovative app that’s popular with both hard-of-hearing and hearing people.

  1. The ASL App
The ASL app sign language

Platform: The ASL App | Course name: Learn ASL Anywhere

The ASL App is focused on teaching you conversational Sign language rather than just letters and words. It’s designed to be accessible and fun, as well as helping to fast-track your ASL learning.

Like the other apps on this list, The ASL App is designed to be used on-the-go and also includes a range of features to help improve your learning experience. Designed by a team of Deaf people, the app’s aim is to bridge communities together and get Deaf and hearing people talking.

You’ll learn:

  • Extensive ASL categories and bundles
  • Designed for complete beginners
  • Informative out-of-lesson content

  • No opportunity to sign 1-1

Who it’s for: This is definitely a course for beginners to American Sign Language. The app designers created the app carefully with this in mind and they expect no prior knowledge of ASL or even of Deaf culture.

Student feedback:This app isn’t perfect, but I love how much the signers clearly enjoyed making it. They make learning the language so much more interesting and even a bit silly (in a totally good way). Just as importantly, I feel like I’m really retaining all the signs they teach.” – Comment from The ASL App

Overall: A really well thought-out app clearly made with a lot of time and effort. The signers do a good job of teaching and expressing Sign across a range of topics. However, the app can sometimes be difficult to navigate and it’s one of the costlier options on this list.

  1. ASL Kids
ASL kids sign language app

Platform: ASL Kids | Course name: Learn Sign

Worthy of mention on this list is the ASL Kids app. With over 226 signs to learn, ASL Kids is an indispensable app for both children and adult beginners.Taking you through basic signs and the ASL alphabet, you can test your learning with quizzes and interactive lessons.

Student feedback: This is truly a beautiful app that is simple, kid friendly, very easy to learn and everything I ever hoped for in an app. It's even easy for adults to learn along with the kids. I hope ASL Kids can keep going because this app has lots of potential to be used at home, in school, at daycare, etc.” – Comment from ASL Kids

Overall: This child-friendly app is suitable for all ages and is easy to follow along with. It uses a range of visual and audio content to get Deaf and hearing people used to ASL. But, one main critique is that it’s fairly basic in terms of its vocabulary – especially if you stick with the free option. That being said, it is a great introduction to American Sign Language for kids and adults alike.

  1. Pocket Sign
Pocket Sign app sign language

Platform: Pocket Sign | Course name: ASL

With Pocket Sign, you can learn hundreds of ASL lessons on-the-go. Pocket Sign’s format is interactive and accessible with video content and a Sign Dictionary. Because of its “fill-in-the-blank” quiz style, you can also learn to translate ASL quickly and easily.

  • Well-designed and fun to use


  • Not always accurate translations
  • Images can make the answers obvious

Who it’s for: This app is best for casual learners who are curious about ASL and want to test out the language in a fun and accessible way. In particular, the dictionary is helpful for looking up key phrases and the Sign Alphabet also includes an excellent graph for fingerspelling. However, it’s not the best app for ASL interpreters as the translations aren’t 100% accurate.

Student feedback:This is what I've been looking for. I'm a visual and kinesthetic learner, and this appeals to both so well. It also has me entranced in the lessons despite my ADHD.” – Comment from Pocket Sign

Overall: An enjoyable app that allows you to learn at your own pace. My main critique is that the on-screen images sometimes make the answers to questions a bit obvious. For example, when asking which gesture means “soup,” an accompanying picture next to the right sign makes it very obvious which one you need to click – even if you’re unsure of the gesture itself!

  1. Marlee Signs
Marlee signs sign language app

Platform: Marlee Signs | Course name: Sign with Marlee

Marlee Signs is an American Sign Language app featuring award-winning Deaf actress, Marlee Matlin. Voted #19 on Apple App Store’s “Top Free Education Apps,” Marlee Signs is one to look out for. The app teaches you the basics of ASL and even has a search function so you can spell out your chosen words.

But, it’s specifically designed to help you express yourself in Sign to those who are Deaf or hard of hearing. Because of this, the app is particularly targeted to those seeking to learn ASL to better communicate with friends and family. You also have the option to download additional packages and to watch offline.

Student feedback:This app is AMAZING! I absolutely love it. I have learned SO much from this app. It's incredible how much you can learn in each package and it's only $2 for each additional package which is a steal. You can learn these on the internet, like everything else, but Marlee has been signing her entire life and knows what she is doing.” – Comment from Marlee Signs

Overall: The Marlee Signs app has generally positive reviews, and Marlee’s celebrity status has helped the app to garner more attention. That being said, there are minor bugs and even some errors affecting the app, so this is something to weigh up against the cost.

  1. SignSchool
SignSchool sign language app

Platform: SignSchool | Course name: Learn American Sign Language

Student feedback:I love this app. I use it everyday as an aide when working with my deaf students. I've learned so much.” – Comment from SignSchool

Overall: SignSchool is an accessible resource for ASL beginners and more advanced students. Its dictionary is one of the most extensive I’ve seen so far and it includes a range of categories from politics and music to Deaf culture. The main letdown here is that the categories are somewhat disorganized and lessons can seem random at times.

What are the advantages of learning from a Sign Language app?

In short, there are plenty! Whatever your reason for wanting to learn ASL, an ASL app is a great way to go. Some of the advantages include:

  • Learning ASL in an interactive way
  • Adapting lessons around your needs
  • Learning at your own pace

  • Immersing yourself in a new subject

Buyers guide: what to look out for in an ASL app

Choosing the right app to learn American Sign Language can seem daunting. You’ll want to choose one that fits your budget and suits both your learning goals and style. In particular, the ASL apps on this list are either interactive in a 1-1 setting (like Preply and italki) or solo-style learning, like The ASL App or Lingvano.

So, we suggest you consider the following points before making a decision:

  • Instructors’ experience — if you’re going to invest time and money into a Sign language app, you want to know that you’re learning accurate information from people who know what they’re talking about.
  • Develop skills — a good ASL app shouldn’t keep you on one level. Instead, it should encourage you to expand your vocabulary and advance in your learning!
  • Great techniques — of course, you want to learn some valuable knowledge that you can put to use in the real world. So, you need to be sure that the app caters to real-world scenarios.
  • Syllabus and skill level — make sure what’s on offer is what you’re looking for! Are you looking for a complete beginner course? Or do you have some basic ASL knowledge that you’re looking to build upon?
  • Price — obviously, you’ll want to choose something that’s in budget. But it’s also important to consider the value you’re getting too. If one app is twice the price but has more state-of-the-art methods and teaching, which one would be more worthwhile?

How much does it cost?

App prices mentioned in this review vary. SignSchool is completely free of charge but the others range from $2.50 per lesson to $9.99 monthly. For italki and Preply, where you choose your price range, you’re looking at between $8 and $30 an hour depending on your tutor.

Some of the apps mentioned here also include lifetime premium or “one time payments.” With Ace ASL, for example, you’re looking at a one-off payment of around $17.

If you factor in each app’s different features and scope, most of these are pretty good value for money (especially as some purchases include all future updates).

So, if you consider the breadth of topics you’ll get with these apps, it usually works out more cost-effective than in-person lessons or tutoring, which can cost at least $20 an hour.

How long does it take to learn American Sign Language?

The apps in this list vary in course content and length. Some provide the basics such as 10-20 lessons in foundational topics. Others are updating constantly to include new features and bundles.

Generally, ASL takes between 3 months to 3 years to learn proficiently. You also need to account for practice time and how you’re learning (with others, from a book, or solely with apps?).

Most people agree that in-app lessons are more efficient when paired with real-life practice or 1-1 tutoring. This is something to bear in mind when considering how much you want to rely on app-based learning.

And, with most of these apps, you choose when and how often to commit and learn more or less at your own pace.

How do we rank our results?

We rank our results according to which apps we believe to be the best.

Inevitably, this is subjective. But the factors we consider include:

  • Teachers’ experience
  • Provides transferable skills
  • Has a strong, varied syllabus
  • Is well taught and explained
  • Student feedback
  • App quality
  • Overall impressions

Where we can, we complete the app courses in order to review them. If this isn’t possible, we do extensive research on the app, its syllabus, and student feedback.


In conclusion, if you’re looking to learn Sign Language on an app, you’re not short of options.

Overall, we feel that Preply is best because of its true-to-life learning style and 1-1 virtual tutoring. Unlike independent-learning apps, Preply has more potential to accelerate your learning and cater to your own learning needs.

Similar to Preply, italki is also a highly revered app that boasts more languages (though few teachers) than Preply. I also found italki’s learning methods to be more relaxed, whereas Preply gets you expressing in your chosen language from the get-go.

So, hopefully, this article has helped you to better understand what the best app to learn Sign Language is for you.

But remember, with these apps, you get out what you put into them, so get ready to practice daily!
