Description
π§ N-Back Trainer — Sharpen Your Working Memory
The N-Back task is the only brain training exercise with peer-reviewed scientific evidence for improving working memory and fluid intelligence. Now you can train anywhere, anytime.
• N-Level from 1 to 6 — start easy, go as high as you can • 15 to 30 trials per round — quick sessions or longer practice • Adjustable speed — 1.5s to 3.0s per stimulus • Sound & haptic feedback — toggle on or off • Dark mode — easy on the eyes
• Accuracy percentage after every round • Detailed trial-by-trial breakdown — see exactly where you fumbled • Running accuracy and streak counter during gameplay • Personal best tracking per difficulty level and mode • Star ratings based on performance (βββββ)
The N-Back task was developed by cognitive scientists and is widely used in research on working memory training. Studies have shown that consistent N-Back practice can lead to improvements in:
• Working memory capacity • Fluid intelligence • Attention and focus • Cognitive control
• 100% Free — no ads, no subscriptions, no in-app purchases • No account required — just open and play • No internet needed — works completely offline • Privacy first — no data collection whatsoever • Clean, minimal design — zero distractions
π‘ TIP: Start with 2-Back. Once you consistently score above 85%, challenge yourself with 3-Back. Most people find 3-Back genuinely difficult — that's where the real training happens.
Don't overthink it. Trust your memory. Download now and start training. π
