About this app
Make the web more comfortable to read. Navidys is a Safari extension that reformats web pages to your reading preferences: spacing, font, size, zoom and colors — adjustable site by site. 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. Navidys gives you precise control over letter spacing and line spacing on every web page. FEATURES - Apply your style to web pages individually - Adjust the spacing between letters and between lines - Use OpenDyslexic, the free typeface created for dyslexia by Abelardo Gonzalez, which some readers find more comfortable — font choice is a matter of personal preference - Adjust font size and zoom on any page - Choose text and background colors for better contrast and visual comfort Navidys is an accessibility and comfort tool. It does not diagnose or treat dyslexia. Your suggestions are welcome!
