How Do Sign Language Apps Work?

How Do Sign Language Apps Work?

Sign language apps include basic signs, especially those that represent letters, numbers, and common words and phrases.

They usually display images of those signs along with detailed video tutorials that users can watch to practice and learn the signs.

Most sign language apps typically work as an ASL dictionary on which people can look up commonly used phrases and words. They allow you to master American Sign Language (ASL) at your own pace as they commonly offer “bite-sized” lessons. 

Some apps also provide a playful user interface, interactive lessons, and game-style quizzes. These apps tend to be better as they enable users to connect the signs with their meanings faster and improve vocabulary comprehension.

However, keep in mind that most ASL apps usually do not provide regional variations of American Sign Language (ASL) and cannot replace a live ASL translator.

Are Apps Effective for Learning Sign Language?

Are Apps Effective for Learning Sign Language?

Most apps that teach sign languages provide basic signs for standard words and phrases. Such apps can help users learn sign language quickly, even within a few days.

However, more advanced signers may need more advanced signs, which may be lacking in some apps.

The National Association of the Deaf (NAD) has stated that American Sign Language (ASL) is a visual language and that the receiver interprets the signer’s facial expressions and body movements to understand the message fully.

So, images are often enough to show basic signs such as letters and numbers. But, some signs may require certain gestures to convey their meaning fully.

That is why apps with detailed video tutorials may be better and more effective than a visual-only app that has only images and pictures.

The findings of a 2019 study stated that teaching mathematical concepts to young students using sign language apps helped them learn faster than old-school learning methods such as boards and flashcards.

Studies have also found that people find apps more engaging and motivating than books or websites. This same result was found for young hard-of-hearing or deaf people and deaf children’s parents and caregivers.

Another study stated that many younger learners interested in learning sign language prefer studying it via digital formats such as online courses and digital dictionaries. Traditional face-to-face classes were the least favored option by the participants in the study.


Sign language apps are an affordable and effective solution for the deaf community and those with functional hearing to communicate with each other easily.

It enables those with intermediate or even basic knowledge of ASL to convey their message to other ASL speakers without the help of an ASL translator or interpreter.

Such apps also allow users to learn even when they are on the move. They can use ASL apps to quickly look up a word or phrase and not get stuck while having a conversation.
