Features & Capabilities

Dual N-Back – Memory Training & Brain Game is a scientifically designed brain training extension that targets working memory and focus. It offers adjustable N level, speed, and session length, plus daily reminders, goals, and global leaderboards to track your progress. It also supports sharing results and multilingual options (English and Japanese).

How it works: You monitor both visual positions and audio letters across N steps back; start at N=2 and the challenge automatically scales with your performance. You can customize N level, speed, and session length, stay motivated with reminders and goals, and compare results on leaderboards. Upgrade to Dual NBack Pro for an ad-free experience and a 3-day free trial to sharpen your cognitive performance.
