ReadFocus+ floats a translucent focus strip over any app on Android and Windows: ebook readers, PDFs, browsers, news and comics. Line Highlight tints the line you are reading so your eyes stay on track; Reading Mask dims everything except your reading zone. Strip height, opacity and 10 colour themes are adjustable. Built for people with dyslexia, ADHD or visual-tracking difficulties, and for anyone who skips lines. Free to use; Pro removes the session limit and ads.
