Dyslexia & ADHD: dys reading

Find the on-screen reading settings that suit you.

For dyslexic and ADHD readers, children and adults alike — and for anyone who tires quickly on screen.

This app is a settings lab: experiment with fonts (including OpenDyslexic), text size, letter and line spacing, and colors on a sample text — and see the result instantly.

IMPORTANT — This app is not a screening or diagnostic tool. Dyslexia is diagnosed by a qualified professional (speech-language pathologist). This app only helps you explore display preferences.

WHY SPACING MATTERS
In a controlled study published in PNAS (Zorzi et al., 2012), increasing the space between letters immediately improved reading accuracy in children with dyslexia — with no training. Effects vary from reader to reader, which is exactly why testing your own settings matters.

WHAT YOU CAN DO
- Try different fonts and compare them on the same text
- Adjust text size, letter spacing and line spacing
- Test text and background colors for your visual comfort
- Send feedback and suggest new settings

Once you know what works for you, apply your preferences in our other apps (Scandys, Navidys, School tool) or in your device's accessibility settings.
