A look inside

SignPal — Progress — **Progress** What you have mastered, what needs work, and how far you have come.

SignPal — Achievements — **Achievements** Points, badges and daily missions for turning up.

SignPal — Settings — **Settings** Camera, difficulty, leaderboard opt-in — all of it yours to set.

SignPal — Changelog — **Changelog** Every version, in the app, so you always know what changed.

It watches your hand

Your webcam feed with a live skeletal overlay, scoring each finger separately and giving you an overall pose match. Not a video you copy — a check on what your hand is actually doing.

12 levels, A–Z and 0–10

Alphabet and numbers, then animals, colours, food, family, school, everyday objects, beginner conversations, common phrases, and emergency signs.

10 games

Letters, Numbers, Speed Challenge, Fingerspelling Challenge and Ladder, Memory, Reflex, Movies, Hangman and JL mode.

Points and a leaderboard

Achievement points, daily missions, and an opt-in online leaderboard for Speed Challenge. Opting out is a single setting.

Your camera stays yours

Hand tracking runs on your own machine. No video is uploaded, and nothing about your practice leaves the app.

Updates itself

SignPal checks this site for new versions and tells you what changed before you install. You never have to come back here for a newer build.

Free, and not the kind of free with a catch

No account, no trial, no locked levels, and no ads inside the app. If you want to put something toward it there is a donate button in the app itself, and ignoring it costs you nothing at all.
