For entertainment and self-comparison
The tests and games on SpeedLab are provided for entertainment and general self-comparison only. They are not scientific, clinical, or diagnostic instruments. A reaction time, click speed, typing speed, or memory score here is not a medical measurement and should never be used to assess, diagnose, or rule out any health condition. If you have a genuine concern about your reflexes, coordination, vision, or cognition, please speak to a qualified professional.
Scores are approximate
Your results depend on things we can't control: your device, browser, screen refresh rate, input lag, and how warmed up you are. The ranks and the "faster than X% of people" figures are based on typical published ranges for each metric and are intended as a friendly point of reference, not a precise percentile against a verified population. Treat them as a ballpark, not a certificate.
No guarantees
We work to keep the site accurate and available, but we make no warranty that it will be error-free, uninterrupted, or that any information in our guides is complete or current. The guides reflect general, widely-accepted information and our own experience building and testing these tools; they are informational, not professional advice. You use the site at your own risk.
