FlowSpeedReader is a powerful speed reading app that uses Rapid Serial Visual Presentation (RSVP) to help you consume text faster than ever before. Whether you're a student, professional, or avid reader, FlowSpeedReader trains your brain to process words at incredible speeds — all while maintaining comprehension. HOW IT WORKS RSVP displays one word (or a group of words) at a time in a fixed position, eliminating the eye movements (saccades) that waste up to 30% of traditional reading time. Your brain focuses purely on processing meaning. Research shows comprehension remains high even above 500 WPM.

About

Text Viewer

Features
Read full description

Long reads, in letters that suit you. Text Viewer is a reader for the text files on your phone. Change the type and the background right where you are reading. FROM THE TYPE TO THE PAGE Drag text size, letter spacing and line height and the page changes under your finger. Nine backgrounds, from sepia to midnight, for bright rooms and dark ones. LONG FILES, A SECTION AT A TIME Once a file is in your library, only the part you are reading is loaded, so long novels stay easy to page through. Very large files may take a moment the first time you bring them in. TURN PAGES, OR SCROLL Read a page at a time like a book, or keep scrolling like the web — switch whenever you like. Your place is kept for you. YOUR LIBRARY Files you bring in stay together in your library. Bring in a newer copy with the same name and it replaces the old one, picking up where you left off. OPEN FROM ANYWHERE Send a text file from Files, your browser or a messenger with "Open in", and it opens straight away. IN YOUR OWN LANGUAGE Eleven languages, following your system or set by hand. Light and dark are drawn by the same rules, so nothing shifts when you switch. Text Viewer has no account and never uploads what you read.
