Braille, in your hands
This is a full braille app, built for blind learners first — every step works by touch and screen reader — and for sighted helpers learning alongside. Letters A to Z, numbers, and a practice ground where you build the cells yourself. Nothing is stored, nothing is sent anywhere; your taps stay on your device.
Learn Braille — the braille learning system
The braille chart — every letter and number
The whole alphabet and the numbers on one calm page, each cell drawn with its dots and named in words. Keep it here, or download it below and carry it anywhere.
The plain-text chart reads well on refreshable braille displays and screen readers: each line names the letter, its braille sign, and its dots.
