Read faster, comprehend more, and save hours every week with ZipWeasel. We combine scientifically proven speed reading technology with custom accessibility tools to help you boost your WPM (Words Per Minute) without sacrificing comprehension. FIVE POWERFUL READING MODES Find the perfect setting for your brain: Focus Mode (Advanced RSVP) The ultimate speed tool. This mode centers every word on a specific "recognition point" (usually the middle letter). By keeping your eye completely still, you eliminate saccadic eye movements and can triple your reading speed instantly. RSVP Mode (Rapid Serial Visual Presentation) A simpler alternative to Focus Mode. This flashes words one by one in the center of the screen without the specific letter alignment. Perfect for users who find the advanced centering too intense but still want high speed. Anchor Mode (Deep Focus) A game-changer for ADHD and Dyslexia. We smartly bold the beginning of every word to guide your eye through the text block. This artificial fixation point prevents lines from blurring together and keeps you in the flow. Highlight Mode (Visual Pacer) Like a digital finger guiding you across the page. This mode highlights text one word at a time as you read, keeping you on track and preventing regression (re-reading lines) without removing the surrounding context. Chunking Mode (Context Reader) Highlights groups of words (2-4 words) at a time. This offers the best balance between speed and context, allowing you to absorb complex phrases naturally. UNIVERSAL DOCUMENT SUPPORT Don't get stuck with an app that only opens plain text. ZipWeasel handles your real-world workflow with zero friction: PDFs & Office Docs: Full support for professional formats including PDF, DOCX, and PPTX. eBooks: Native EPUB reader support for your digital library. Web Articles: Paste any URL to instantly convert cluttered websites into clean, speed-readable text. Images & Scans: Built-in OCR converts photos of textbooks or physical papers into digital text instantly. AI-POWERED INTELLIGENCE Instant Summaries: Short on time? Let our AI extract key points and generate concise summaries of long documents in seconds. CUSTOMIZE YOUR EXPERIENCE Visual Comfort: Full Dark Mode, OpenDyslexic font support, and adjustable text sizing to reduce eye strain. Speed Control: Fully adjustable WPM settings to match your reading level. Smart Navigation: Search within docs, bookmark key sections, and resume exactly where you left off. Track Your Growth: Visualize your progress with interactive charts and earn achievements as you improve. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

About

Readlio

Features
Read full description

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.
