DEVOUR YOUR READING LIST Download free and start speed reading in seconds. Devour uses RSVP (Rapid Serial Visual Presentation) to display words one at a time right where your eyes are focused—so you read 2-3x faster without learning any special technique. Just import, tap play, and devour. HOW IT WORKS Traditional reading wastes time on eye movements. Devour eliminates that by presenting each word at a fixed point with the Optimal Recognition Point highlighted, so your brain processes text faster instantly. IMPORT ANYTHING EPUBs, PDFs, web articles, DOCX, TXT, Markdown, HTML, RTF—if you can read it, Devour can speed-read it. Paste text or extract content from any URL. Your entire reading list in one app. POWERFUL FEATURES Speed Control — Adjust from 100 to 1,000+ words per minute. Start at your comfort zone and gradually increase as your brain adapts. Built-In Speed Test — Discover your baseline reading speed, then see how much faster you read with RSVP technology. Progress Tracking — Resume exactly where you left off. Every document saves your position automatically. Reading Statistics — Track total words read, reading time, average WPM, and daily streaks with beautiful visualizations.

Dark Mode — Automatic system theme matching or manual light/dark selection for comfortable reading anywhere. THE SCIENCE RSVP has been researched for decades as a method to increase reading speed. By presenting words at a fixed focal point with ORP highlighting, your visual system processes text more efficiently. Most readers see significant speed improvements from their very first session.
