Hi HN,

I built N-Back.net, a lightweight and responsive Dual N-Back task for working memory training.

I was frustrated by the clunky UI and heavy design of most existing n-back tools, so I made something clean, fast, and distraction-free. No login, no ads, no tracking – just cognitive training in your browser.

Key features: • Dual mode: visual + auditory • Adaptive difficulty: level up as you improve, drop down if needed • Dark mode and keyboard-only mode • Clearly differentiated letter sounds, carefully selected to avoid confusion • Performance tracker (WIP: I’m working on streaks and detailed history) • Mobile-friendly (works well on phones & tablets)

I’m planning to add: • Custom training modes (single-modality, color, etc.) • User-defined N range • Optional accounts for progress saving (but always optional)

Would love your feedback on: • UX flow and performance • Cognitive challenge balance • What would make you come back and use it regularly?
