The N-Back Plateau Problem, Solved
Standard N-Back tools force large, discouraging difficulty jumps. Our fine-grained system provides 100 adaptive micro-steps (N.00-N.99) per N-level, keeping you precisely at the edge of your capability – where cognitive growth happens. Multiple session parameters adapt automatically with each small step.
- Dynamically adjusts ISI, stimulus duration, match density, and lure frequency based on your N-Back performance.
- Uses d′-prime thresholds instead of raw accuracy to determine your optimal N-Back challenge level.
- Automatically advances N-level after consistent good performance at max difficulty, preventing endless grinding.
Smooth vs. Traditional Steps
Beyond Simple Accuracy: d′-Prime Insight for N-Back
Raw N-Back accuracy is misleading – 90% could mean excellent discrimination or just lucky guessing with response bias. Our platform uses d′-prime (d-prime), the signal detection measure used in cognitive research, to precisely quantify your N-Back working memory performance. Compare periods side-by-side, track trends, and get a scientifically sound picture of your true cognitive improvement.
- Measures N-Back signal detection ability - distinguishes hits from false alarms for accurate working memory assessment.
- Track multiple key N-Back metrics: Avg N-Level, Focus Level, False Alarm Rate, Play Time, Session Count, and more.
- Save chart snapshots directly to your training journal to correlate N-Back performance with subjective states and external variables.

Track Genuine WMC Growth, Beyond N-Back Skill
Is your N-Back training improving underlying Working Memory Capacity? Our standardized Counting Span Task (CST) provides an objective answer. By requiring simultaneous processing (counting shapes, judging odd/even) and storage (remembering counts), it measures core WMC. Complete monthly to track genuine progress with the validated Partial Credit Unit (PCU) score (0-75), independent of specific N-Back strategies.
- Objective WMC Measure: Assess core capacity via a scientifically validated Complex Span Task.
- Longitudinal Tracking: Monitor true capacity changes over months, separate from N-Back level fluctuations.
- Validated Scoring: Uses PCU scoring and requires >85% processing accuracy for reliable measurement.
Is the count Odd or Even?

Monthly AssessmentUncover Your Optimal Training Conditions
Working memory training is affected by countless variables – time of day, sleep quality, stress levels, strategy, and more. Our integrated journal helps you discover what actually works for you. Automatically log session data, manually track subjective states, tag entries for patterns, and correlate performance (both N-Back and WMC) with external factors.
- Auto-save key metrics (N-Level, d′, WMC Score) with each session/assessment for effortless record-keeping.
- Use custom tags (e.g., #morning, #rested, #strategy-chunking) to reveal hidden patterns.
- Integrate chart snapshots, session replays, and notes in one place for comprehensive training intelligence.
Morning Session - Peak Focus
Apr 12Felt great after meditation. Reached new best N=3.65, d'=3.2. Morning is key.
Trying Spatial Chunking
Apr 10Experimenting with grouping visual stimuli. Felt harder initially, but maybe promising...
Evening Session - Tired
Apr 9Definitely lower N-Back performance tonight. Sleep matters! d' dropped to 1.9.
