N-Back Trainer

🧠 N-Back Trainer — Sharpen Your Working Memory The N-Back task is the only brain training exercise with peer-reviewed scientific evidence for improving working memory and fluid intelligence. Now you can train anywhere, anytime. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🎯 HOW IT WORKS You'll see a sequence of letters or positions, one at a time. Your job? Decide if the current item matches the one from N steps ago. Example (2-Back): F → K → F → … The second F matches the F from 2 steps ago — tap MATCH! Simple to learn. Incredibly hard to master. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🕹️ TWO GAME MODES 📝 Letter Mode — Remember sequences of letters 📍 Position Mode — Remember positions on a 3×3 grid Each mode trains different aspects of your working memory. Letter mode challenges verbal memory, while position mode targets spatial memory. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ⚙️ FULLY CUSTOMIZABLE • N-Level from 1 to 6 — start easy, go as high as you can • 15 to 30 trials per round — quick sessions or longer practice • Adjustable speed — 1.5s to 3.0s per stimulus • Sound & haptic feedback — toggle on or off • Dark mode — easy on the eyes ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 📊 TRACK YOUR PROGRESS • Accuracy percentage after every round • Detailed trial-by-trial breakdown — see exactly where you fumbled • Running accuracy and streak counter during gameplay • Personal best tracking per difficulty level and mode • Star ratings based on performance (⭐⭐⭐⭐⭐) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━ 🔬 BACKED BY SCIENCE The N-Back task was developed by cognitive scientists and is widely used in research on working memory training.
