Super Dyslexia Harmonia Release 3.Harmonia prioritizes calm familiarity and contemporary professional texture.

The website can be switched between the Harmonia cuts from the Font selector in the top menu. The selection persists locally across public pages.

## Evidence trail

82 structured research records and 24 documented design decisions are published on the site. The project is research designed and evidence traceable, but it is not a medical device, diagnosis or treatment and is not yet claimed to improve reading performance for every dyslexic reader.

## Type Studio

The live Type Studio exposes the actual shipping fonts and lets readers compare Harmonia Reading and Display while controlling Reading or Display cut, weight, size, letter spacing, word spacing and line height.

## Published coverage

The current release covers Latin, extended Latin, Vietnamese, modern Greek, modern Cyrillic, combining marks, punctuation, currencies, arrows, mathematics and related symbols. See https://superdyslexia.com/coverage.html for boundaries.
