Overread
Read full descriptionHide full description
The average person reads 250 words per minute. With proper training, you can double or triple that speed without sacrificing comprehension. OverRead is designed to unlock your brain's full potential and transform you into a more efficient reader. Two Powerful Reading Modes Highlighting Mode presents your complete text with a smooth, animated highlight moving at your chosen pace. You see the full context while the highlight guides your eyes, preventing regression and maintaining consistent speed. RSVP Mode takes a more aggressive approach. Words appear in the center of your screen, eliminating eye movement entirely. This removes one of the biggest physical limitations on reading speed, letting you reach speeds you never thought possible. Both modes offer adjustable speeds from 100 to 1000 words per minute. Start comfortable, then gradually increase as your abilities improve. Chunk Size Control Skilled readers process multiple words simultaneously. Adjust chunk size to control how many words appear together. Train your peripheral vision and develop the wide visual span that characterizes expert readers. Your Personal Library Build your collection from multiple sources. Paste text directly, import articles from any URL with automatic content extraction, or add EPUB books and PDF documents. Every item tracks your reading progress so you can pick up exactly where you left off. Comprehensive Statistics Track your daily reading time, weekly trends, completed articles, and average speed. The streak system encourages consistent practice. Regular training, even a few minutes daily, leads to significant improvements over time. Customizable Experience Four themes to match your preference: Modern, Classic, Sepia, and Dark. Adjust font and size for comfortable reading. Set default speed and mode so the app is ready when you are. Practice Templates Built-in content covering focus, productivity, learning techniques, and the science of speed reading. Quality practice material that teaches valuable skills while you train. OverRead+ Premium Unlock speeds up to 1000 WPM, unlimited library storage, progress saving across all content, and access to all themes. For Everyone Who Reads Students processing textbooks. Professionals staying current with industry news. Book lovers working through their reading lists. Anyone who reads regularly will benefit from speed reading training.
