What it measures

How Halo feeds your trends

Every session contributes to your Speed rating, which rolls into your Brain Fitness Index — a single 0–100 score across all six skills. Difficulty adapts to you, so Halo stays in your stretch zone, and you can review how it trends over time on the web dashboard.

CogDojo measures and motivates your training. It is not a medical product and does not diagnose, treat, or prevent any condition.
