Span N-Back
Train Your Working Memory
Free · Designed for iPad. Not verified for macOS.
Train your brain with the gold standard of cognitive training.
Span N-Back is a scientifically-designed working memory training app based on the dual n-back task — the only cognitive training method shown in peer-reviewed research to improve fluid intelligence.
WHAT IS N-BACK TRAINING?
The n-back task challenges you to remember sequences of positions and sounds, then identify when the current stimulus matches one from "n" steps back. It's simple to learn but progressively challenging, keeping your brain in the optimal training zone.
WHY SPAN N-BACK?
• Research-Based Design — Built on the Jaeggi dual n-back protocol used in cognitive science studies
• Precision Timing — Sub-20ms stimulus accuracy for reliable training
• Progressive Difficulty — Levels 1-9 adapt to your growing abilities
• Dual Modality — Train visual and auditory working memory simultaneously
• Detailed Analytics — Track accuracy, reaction time, and progress over time
• Privacy First — All data stays on your device. No accounts, no tracking.
WHO IS THIS FOR?
Whether you're a student preparing for exams, a professional seeking mental edge, or anyone interested in cognitive fitness — consistent n-back training can help sharpen focus, improve working memory capacity, and enhance mental agility.
