SpeedReading uses proven neuroscience techniques to help you read faster while keeping comprehension high. Whether you are a student, professional, or avid reader, this app gives you a structured daily training program that adapts to your skill level. HOW IT WORKS SpeedReading combines two powerful methods into one seamless experience: Anchor Reading highlights an anchor letter at the optimal viewing position of each word, with the first portion in bold and the rest in a lighter weight. Your brain uses these visual cues to recognize words faster without reading every letter. RSVP (Rapid Serial Visual Presentation) displays one word at a time in a fixed position on screen, eliminating the eye movements that slow down traditional reading. Together, Anchor RSVP lets you push past your natural speed ceiling while maintaining focus. TRAINING MODULES - Anchor RSVP: The core training module. Words flash on screen with anchor-letter highlighting and variable font weight. Speed adapts automatically based on your comprehension accuracy. Includes save and resume so you never lose progress mid-session. - Speed Test: Measure your baseline reading speed with timed passages and comprehension quizzes. Track your WPM improvement over time with detailed results and personalized feedback. - Peripheral Vision: Expand your visual recognition span with rapid flash drills. Words and phrases appear briefly in your peripheral field. Identify them correctly to train wider fixation, reducing the number of eye movements per line. - Word Chunking: Practice reading groups of words together instead of one at a time. Adjustable chunk sizes and speeds help you build the habit of phrase-level reading, a key skill for faster comprehension. - Reading Library: Browse 22 curated passages across 14 categories and 3 difficulty levels. Every passage is rendered with anchor formatting. Adjust fixation ratio and font size to match your preferences. - Daily Training: A guided routine that combines peripheral warm-up, chunking practice, Anchor RSVP, and guided reading into one focused session. Complete all four steps to build a consistent daily habit. PROGRESS AND ANALYTICS - WPM tracking with interactive line charts filterable by week, month, or all time - Activity heatmap showing your 35-day training history at a glance - Streak tracking with daily goal progress rings - Session history with per-module breakdowns - 24 achievement badges across 5 categories: Speed, Consistency, Volume, Comprehension, and Exploration - Bronze, Silver, Gold, and Platinum tiers to keep you motivated BUILT FOR READERS SpeedReading is designed with a clean, modern interface that works beautifully in both light and dark mode. The app uses a warm amber color system with glassmorphic surfaces for a premium feel that keeps the focus on your training. Start with a free trial and unlock unlimited access to all modules, the full content library, advanced analytics, and every achievement badge.
