ReaderPro helps you build speed-reading skill with short, focused daily drills. Train the pieces that make faster reading feel easier: visual scanning, peripheral awareness, word recognition, attention, working memory, and reading rhythm. Each session gives you a concrete exercise instead of vague advice like "just read faster". FEATURES: 12+ Training Exercises Practice with Schulte Tables, Running Words, Word Chains, Letter Search, Number Search, Line of Sight, Remember Number, Search Words, and more. Guided Training Plans Choose quick sessions that fit your day, then build consistency across focus, memory, reading flow, and visual-control drills. Adaptive Difficulty Exercises stay challenging as you improve, so practice feels active without turning frustrating. Progress Tracking Follow your scores, streaks, and training history so you can see what is actually improving. Reading + Focus Workouts Train the eye movement, attention, and memory skills that support faster, more controlled reading. Clean, Minimal Design A simple interface keeps the drill in front of you and gets out of the way. ReaderPro is designed for students, professionals, researchers, and curious readers who want to read faster, stay focused longer, and make reading practice measurable.
