Reaction time test
Wait for cyan, click fast. Five rounds, averaged. Early clicks restart the round.
Frequently asked questions
What is a good reaction time?
The median for a simple visual click test sits around 250 ms. Under 220 ms is quick, under 200 ms is rare, and scores below about 150 ms are usually anticipation rather than reaction.
Why is my score worse on a laptop trackpad?
Hardware adds real latency: trackpads debounce, wireless mice buffer, and a 60 Hz screen refreshes every 16.7 ms. The same person can differ by 30 to 50 ms between setups, so compare scores on the same device.
Does reaction time improve with practice?
A little. You can shave maybe 10 to 20 ms by staying relaxed, focusing on the color change rather than the whole screen, and clicking with a ready finger. Sleep and caffeine matter more than grinding attempts.
Why five rounds?
Single attempts swing wildly, one lucky anticipation or one blink changes everything. Averaging five rounds gives a number stable enough to compare day to day.
