How do I run a session?
Click or tap the target to start. After an unpredictable wait, it turns green and says to click or tap. Use your main mouse or trackpad button, or tap with one finger. The same target starts the next round.
Reaction Click Test
Wait for the green signal, then click or tap as quickly as you can. Finish five rounds to see your reaction times.

How to use the Reaction Click Test
What if I go too early?
An early press is a false start. You’ll get another try at the same round, and the early press stays out of your timing results. If you leave the tab mid-round, that round ends and your completed rounds stay put.
What does my score mean?
Line up the five times from fastest to slowest and take the middle one. That’s your median. It gives you a better sense of a typical round when one attempt was unusually fast or slow.
Can I compare devices?
Use the same browser, display and input for the fairest comparison. A different setup can change the score even when your reaction feels the same. This is a visual reaction test and can’t isolate mouse or touchscreen latency.
