Wait for the panel to turn green, then click as fast as you can to measure reaction time in milliseconds. Track your best and average scores for the session.

How to use this tool

1. Start the test and wait for the signal. 2. Click or tap as soon as the target changes. 3. Review your reaction time in milliseconds. 4. Repeat several rounds and compare the average rather than one attempt.

Worked example

Example: complete five rounds with times of 248, 231, 260, 244, and 239 ms, then use the average to compare later practice.

How it works

Click Start, wait for the panel to turn green, then click as fast as you can. If you click too early while the panel is red, the attempt does not count. Your best and average reaction times stay on this page only.

Limitations

Results are based on the inputs you provide and may not cover every edge case. This tool is for general use and is not professional advice.

Privacy and file handling
