Features — ASL Buddy

An ASL course with its ordered lessons and a Start Course button — Course & lessons

Learn

Lessons that teach, then check, in one smooth flow

Each lesson plays as one continuous run that weaves teaching screens (a real sign video plus how to form it) together with quiz questions placed right after the sign they test. You're checked on each sign while it's still fresh, with a running score, a Check button, instant feedback, and a Lesson Complete summary at the end. No separate quiz to dread, just learning that confirms itself as you go.

23 courses — from first signs to fluent conversation, classifiers, and Deaf culture
Real sign videos — every sign is taught with video, not just a written gloss
Teach + test together — quiz questions land right after the sign they cover

Quiz

Nine question types that fight the way ASL is really confused

ASL Buddy mixes nine question types: pick the right sign video, watch and choose the meaning, type the meaning from memory, true/false, minimal-pair and handshape-parameter questions, fingerspelling decode, match-the-pairs, and expressive prompts where you sign from memory then self-check. Because confusion in ASL is visual, the wrong answers are chosen to look like the right sign, and Auto difficulty quietly tunes that challenge to your recent accuracy so it's never too easy or overwhelming.

Look-alike distractors — wrong answers are chosen to look like the right sign
Adaptive difficulty — Auto tunes the challenge to your recent accuracy
Sign, don't just read — expressive prompts ask you to produce the sign from memory

The Review tab with streak and due counts — Daily review

Remember

A review system that makes signs actually stick

Every sign you learn is scheduled by FSRS-6, the same modern memory algorithm that powers Anki, which delivers the same retention as older systems with 20 to 30 percent fewer reviews. Short daily sessions resurface what's due in both directions, expressive (perform the sign) and receptive (watch a real sign video and recall its meaning), and you grade yourself Forgot, Struggled, or Got It. A streak banner plus Today, Learned, and In Queue tiles keep your progress visible and your habit alive.

A sign detail page with production notes and memory aids — Sign detail

Reference

A 4,300+ sign dictionary that knows how well you remember

Tap any sign for a looping video you can view full screen, a Your Memory panel showing your current recall probability and next review, How to Sign It instructions, a How to Remember It memory aid, and a Production breakdown of handshape, orientation, location, movement, and expression, often with a reference image, plus a Did You Know fact. You can favorite a sign or add it straight to your daily reviews. It teaches the building blocks, not just the look.

4,300+ signs — searchable, filterable, and browseable by handshape
