How to test
Click to begin, wait for green, then click again. A click before green is recorded as an early start. Repeat after the result screen.
What the result means
The time includes your reaction, display and input delays, and browser scheduling. It is not an isolated mouse-latency measurement or a medical assessment.
What to do next
Compare several attempts on the same device and browser. Do not compare the result to unsourced athlete rankings or use it to diagnose health conditions.
