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

About

Readlio

Most speed-reading apps hand you an empty box and a stopwatch. Readlio comes with 70,000+ free books and every Wikipedia article plus six training games, two reading modes, and a comprehension check that tells you whether you actually understood what you just sped through. READING FAST IS EASY. REMEMBERING IT IS THE HARD PART. Classic RSVP flashes one word at a time at a fixed focal point. It's fast but research shows that removing your ability to glance back hurts comprehension. So Readlio gives you a second mode. Highlight Flow keeps the entire text on the page while a highlight travels through it at your chosen speed. Slightly slower, dramatically better recall, and you can always look back at the sentence you just passed. Switch between them any time. Your place is kept. SOMETHING TO READ, INCLUDED • 70,000+ public domain books from Project G • Every Wikipedia article, in five languages • Import your own PDF, EPUB, DOCX or TXT • Paste text or load any web article • Everything you open is cached for offline TRAIN, DON'T JUST MEASURE • Schulte tables for peripheral vision • Peripheral vision, chunking and eye-tracki • Anti-subvocalization practice • Memory and recall games • A 60-second warm-up before every session • Adaptive speed that adjusts your WPM based BUILT TO KEEP YOU COMING BACK • Daily reading goal with a gentle reminder only on days you haven't hit it • Streaks, with a weekly streak freeze so onth • 17 achievements, XP and levels • Weekly league tiers • Full statistics: words, time, speed, and progress per document MADE FOR EVERY READER • Dyslexia mode with Open Dyslexic • Adjustable letter spacing and line spacing • High contrast option • 28 reading fonts, or import your own • 12 reading themes • Read-aloud with the iOS voice of your choice • Full app in English, Türkçe, Español, Deut YOUR READING IS YOURS No account.
