Free screening for dyscalculia, ADHD indicators, and a full cognitive profile across 7 domains. 29 research-backed tests, all running in your browser. Some are timed or rely on quick responses, and each one explains what it involves before you start.
A structured screening for dyscalculia, the specific learning difference that affects how your brain processes numbers. Covers number sense, arithmetic fluency, and the cognitive foundations that support math.
Measures the core attention dimensions that differ in ADHD: sustained focus, impulse control, response consistency, and processing speed. Not a diagnosis, but a data-driven starting point for understanding how your attention works.
