STOP READING. START ABSORBING. Most people read at about the same speed they speak. The reason is subvocalization: the small inner voice that sounds out every word. Absorb is built to break that bottleneck and change how you move through text. Absorb uses an advanced Rapid Serial Visual Presentation (RSVP) engine. Instead of making your eyes scan back and forth across a page, it shows words one after another in the same spot and highlights each word's Optimal Recognition Point. Your gaze stays centered, your focus stays locked, and text moves straight into visual processing. WHY READERS USE ABSORB STEADY FOCUS: The rapid display leaves less room for wandering attention and helps you enter a steady reading flow. BUILD THE HABIT: Track daily streaks, average WPM, reading time, and progress so speed becomes something you can actually train. BRING YOUR OWN BOOKS: Import EPUB, PDF, TXT, and pasted text from your device. LESS EYE FATIGUE: Stop losing your place. Sit back, watch the center, and let the book come to you. PRIVATE BY DESIGN: Processing happens locally on your device. Your files and reading data do not leave your phone. Absorb offers monthly access and a one-time Lifetime unlock. Full access requires a subscription or Lifetime unlock. Download Absorb, import your first book, and finish it tonight. Terms: https://absorb-app-ncmw.onrender.com/terms.html

Verdict
The clearest difference is ads: Read Fast at none against Devour's shown. Read Fast also leads on update cadence (every 2 days vs weekly). Devour's advantage is iOS requirement (13.4 vs 16.4). On price, in-app purchases and device support there is nothing between them.
