iBrain Gym
Cognitive Pattern Measurement

A web-based system that measures cognitive performance through short behavioural tasks and tracks how responses change over time using a personal baseline model.

Longitudinal cognitive tracking

Personal baseline model

Problem

Single-session
scores fall short

Most cognitive tools rely on single-session scores or population averages. These approaches fail to capture how cognitive performance fluctuates over time — and they cannot distinguish meaningful change from normal day-to-day variation within a given individual.

Solution

Longitudinal,
within-subject model

iBrain Gym introduces a measurement approach that compares each session against the user's own established baseline — not against population norms. This makes it possible to detect changes that are meaningful for that individual.

Reaction

Measures response latency under controlled conditions

Memory

Short-term recall tasks with variable load

Flexibility

Task-switching and inhibition measures

Personal baseline

Within-subject model built from repeated sessions

Change detection

Statistical thresholds distinguish meaningful shifts from noise

Key Features

Built for
precision

  • 60-second assessment

    Three short tasks covering reaction speed, working memory, and cognitive flexibility — completed in under a minute.

  • Adaptive scoring engine

    Z-scores, standard error of measurement, and trend analysis calibrated to each user's own baseline.

  • Pattern detection

    Statistical thresholds flag meaningful changes across sessions, distinguishing signal from normal variation.

  • AI interpretation layer

    OpenAI-powered summaries translate raw scores into clear, readable session insights.

  • Secure identity infrastructure

    Face verification and liveness detection via BioID, combined with OTP authentication through Twilio.

Outcome

Cognitive consistency
over time

iBrain Gym enables users to understand their cognitive consistency over time, rather than relying on static scores. By building a personal baseline and applying statistical change detection, the system surfaces patterns that would otherwise remain invisible in single-session assessments.

Part of the iBrain Lab portfolio

iBrain Gym is developed under iBrain Lab — a research and product initiative focused on behavioural measurement and cognitive pattern analysis.
