Train Your
Working
Memory
Dual N-Back is one of the few cognitive exercises with peer-reviewed evidence for improving fluid intelligence and working memory capacity. Track two stimuli simultaneously and push your mental limits.
Why Dual N-Back Works
Working Memory
Working memory is the mental workspace you use to hold and manipulate information in real time — essential for reasoning, learning, and problem-solving.
Fluid Intelligence
A 2008 study by Jaeggi et al. showed that Dual N-Back training produced significant gains in fluid intelligence — the ability to reason and solve novel problems.
Dual Stimuli
By tracking both visual positions and auditory letters simultaneously, Dual N-Back engages multiple working memory subsystems at once, maximizing the training effect.
Adaptive Difficulty
The N-back level adjusts to keep you at the edge of your ability. Training at your limit — not below it — is what drives cognitive improvement.
