Train your working memory with N-Back. N-Back is a focused brain-training game built around the Dual N-Back task: remember where the square appeared and what letter you heard, then respond when either one matches N steps back. It is simple to learn, hard to master, and perfect for short daily focus sessions. WHY N-BACK? Dual N-Back is widely used in cognitive training and working-memory research because it asks your brain to hold, update, and compare information in real time. N-Back turns that task into a clean daily practice you can actually stick with. FEATURES: 20-Day Challenge Build a consistent habit with a structured daily program. Track your streak and finish bite-sized sessions without overthinking what to do next. Dual Visual + Audio Training Follow both the grid position and spoken letters at the same time. Train attention, memory, and response control in one compact exercise. Adaptive Difficulty The challenge grows with you, keeping sessions demanding without making them feel random or impossible. Practice Mode Train without affecting your streak. Adjust the N-level and experiment at your own pace. Progress Stats See your sessions, scores, streaks, and level changes over time so improvement feels visible. Clean, Focused Design A minimal interface keeps the exercise front and center. No clutter, no gimmicks. HOW TO PLAY: Position Match: tap when the square matches the position from N steps back. Sound Match: tap when the spoken letter matches the one from N steps back. Dual Task: track both at once and push your working memory. Start with a short session today and build the habit. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
