A free sign language app teaches you signs through short videos, quizzes and practice, so you can learn the alphabet and everyday phrases at your own pace. Course-style apps suit steady learners, while dictionary apps suit looking up a sign fast. Check which sign language an app teaches, because it isn't the same in every country.
More people than ever want to learn sign language. Some have a deaf friend, relative or colleague, some work with the public, and some simply want to understand the interpreter on the news.
Here are ten free sign language apps, listed in no particular order and sorted alphabetically. Most teach American Sign Language, and they range from structured courses to quick dictionaries.
Video matters more here than in almost any other kind of learning app. Signs depend on hand shape, movement and facial expression, so clear, slow video from fluent signers makes all the difference.
Before you choose, it's worth knowing one fact that surprises most beginners about sign language around the world.

Why sign language isn't the same everywhere
Here's the fact that surprises most beginners. There's no universal sign language. The US National Institute on Deafness and Other Communication Disorders says different sign languages are used in different countries or regions, and that British Sign Language is a different language from ASL.
It even notes that Americans who know ASL may not understand British Sign Language. That's a bigger gap than most people expect, because English speakers in both countries understand each other with little trouble. So if you're learning to talk with someone in the UK, Australia or elsewhere, check which sign language they use before you pick an app, because most free apps teach ASL.
What to look for in a sign language app
- Fluent, deaf signers: lessons led by native signers show natural movement.
- Clear video: you need to see hands and faces from the front.
- Fingerspelling practice: the alphabet helps with names and new words.
- Facial expression: good apps teach it, because it changes meaning.
- A dictionary: handy for looking up a sign in the moment.
Learning your first signs
- Learn the fingerspelling alphabet first.
- Practise greetings and your name.
- Add the signs you'd use every day, such as thank you and please.
- Watch the videos slowly and copy them in a mirror.
- Practise with a deaf friend or a local class when you can.
Keep your sessions short. Ten minutes of copying signs carefully does more than an hour of skimming videos, because your hands need repetition to remember the shapes.

My plain advice on free sign language apps
Pick an app taught by deaf signers and stick with it for a few weeks before you try another. Little and often beats a long session once a week, especially with fingerspelling.
And remember that an app gets you started, but conversation with deaf signers is where you'll really learn. Look for a local class or a deaf community event when you're ready.
