A dual n-back trainer built for performance. Precise audio-visual synchronization and instant feedback. Train your working memory — the mental ability behind focus, learning, and problem-solving. N-Back Hz is designed for serious practitioners who want a fast, responsive, and deeply configurable training experience. Built from the ground up, N-Back Hz delivers zero-lag stimulus timing that you can feel from your first session. THREE WAYS TO PLAY — Campaign — structured tracks across Beginner, Variants, Speed, Patience, and Endurance, each with leveled progression and perfect-run stars — Daily Training — a focused routine with streaks, weekly progress, and a daily target — Quick Play — pick an N and go, with full per-session control ADAPTIVE SKILL RATING An Elo-inspired rating system tracks your ability per configuration. Your first 10 blocks calibrate faster, then the system smoothly adjusts based on sustained performance — no jarring jumps from a single lucky or unlucky block.
