ReadingVelocity Read Faster. Remember More. In an age of endless scrolling and AI summaries, deep reading is becoming a lost art. ReadingVelocity is the training app that brings it back—treating reading like endurance athletics to build your Attentional VO2 Max: the cognitive stamina to sustain deep focus through dense texts. Developed by an educator and ultramarathoner with 25+ years teaching at Yale, The New School, and beyond, ReadingVelocity applies progressive overload to your brain. No gimmicks—just a proven, structured protocol that helps you read better, faster, and more. How It Works – The Three Readings in One Protocol PRIME (6%) – Your pre-race brief. Survey the terrain, set intention, and create mental hooks. PUSH (82%) – Sustained immersion at an “uncomfortable rate” (Cornell Rapid Reading) to break slow habits and build speed. PROCESS (12%) – Recovery and mastery. Catch key ideas, connect them to what you know, and clash with dissonance. Key Features Free Read – Train for time and focus. Paced Read – Finish assignments with precise page targets and WPM tracking. 90s Warm-Up Drills – Silencer Sprint (RSVP), Signal Scan, Peripheral Push. Coach's Log – Post-session feedback with coaching-inspired breakdowns. Log & Stats – Track Focus Score, WPM, streaks, and pages completed. Local Storage – Your data stays on your device. Why It Matters For 25 years I’ve refined this method in the classroom, helping students transform from passive readers into passionate, critical, and faster ones. Now I’m giving it away free to the world. The same protocol that helped students conquer 1,000-page epics can now help you reclaim deep reading in an age of distraction. Read Faster. Remember More. Your brain is a muscle. Let’s train it.

Practise spatial skills for 11+ non-verbal reasoning and CAT4-style spatial tasks. Preparing for grammar school or independent school assessments? Foldmetry offers short, focused practice in visualising shapes, understanding folds, and reasoning in 3D. Use it alongside your wider preparation: it is not a complete 11+ or CAT4 course and does not reproduce official tests. Foldmetry turns six spatial-reasoning skills into clear, interactive exercises: • Mental Rotation: recognize a solid after it turns in 3D • Cube Nets: predict how a flat net folds into a cube • Perspective Taking: visualize structures from another viewpoint • Paper Folding: reverse folds and predict position patterns • Block Assembly: count volume, missing cubes, and exposed faces • Cross Sections: find exact slices through 3D structures START FREE Start all six paths, complete the first two lessons in each path, try a daily mixed session, and review up to three missed questions at a time. Best scores, stars, streaks, and recent progress stay on your device. TIMED EXAM-STYLE PRACTICE With Pro, try 12 mixed questions across all six skills, with 40 seconds per question. Review accuracy and response time by skill to plan your next session. This is Foldmetry's own practice format, not an official exam simulation. PRACTICE YOUR WAY WITH FOLDMETRY PRO Unlock all 36 guided lessons, full ten-question Mistake Review, unlimited practice at difficulty levels 1–10, selectable session lengths, and complete training history. Choose an annual subscription with a 7-day free trial for eligible customers, or unlock Pro with a one-time lifetime purchase. Pricing and eligibility appear in the App Store purchase sheet. Restore purchases at any time from Settings. PRIVATE BY DESIGN No account. No ads. No behavioral tracking across apps or websites. Your training history, mistake queue, and preferences remain on your device. Foldmetry uses privacy-friendly anonymous analytics (TelemetryDeck) to understand which features help; you can turn this off in Settings. Exercises and licensed paper-folding animations work offline; a network connection is used for App Store purchases and optional analytics. Foldmetry is an independent educational practice tool. It does not measure IQ, provide medical advice, guarantee academic or exam results, or claim affiliation with any examination authority. CAT4 is a GL Assessment test; Foldmetry is not affiliated with or endorsed by GL Assessment.
