What is N-Back Boost?

N-Back Boost is a free, browser-based Dual N-Back training app designed for anyone serious about improving their working memory and cognitive performance : no downloads, no subscriptions, no fluff.

What is Dual N-Back? Dual N-Back is one of the most studied cognitive training tasks in neuroscience. You simultaneously track two streams of information — visual position and auditory sounds — going back N steps. Regular practice has been linked to gains in fluid intelligence, sustained attention, and processing speed. Why N-Back Boost?

? 100% Free: no paywalls, no premium tiers ? Works on any device: mobile, tablet, or desktop ? PWA-ready: install it like a native app, train offline ? Clean, distraction-free UI: designed to keep you in flow ? Adaptive difficulty: automatically adjusts the N level as you improve ? Session stats & progress tracking: see your cognitive gains over time ? No account required: start training in seconds

Who is it for? Students, productivity enthusiasts, ADHD self-coaches, and anyone curious about evidence-based brain training. If you're looking for a lightweight, science-grounded alternative to Lumosity or BrainHQ, N-Back Boost is built for you.
