Best average: not set yetSaved only on this device.
The average person is often quoted at roughly 250 milliseconds for a visual reaction, but that is only a rough reference: your screen, browser, input device and connection add delay, so compare your own results over time rather than with other people. This is a game, not a medical test.

- 02When it turns green, tap as fast as you can.

About this tool
Tap the big box to begin. After a random wait of one and a half to four and a half seconds it turns green, and the clock starts. Tap as fast as you can and your time appears in milliseconds. If you tap too early the attempt is cancelled and you try it again. After five valid attempts you get your average, your fastest tap and the median.
For a rough idea of where you stand: people are often quoted at around 250 ms for a visual reaction, but this is only approximate. Your screen’s refresh rate, your browser, mouse or touch screen and any input lag add delay, so compare your results with your own earlier scores on the same device. Being tired, distracted or in a hurry shows up quickly.
It is a game, not a medical or driving test. Your best average is saved in your browser on this device only, and there is a button to reset it. Nothing is uploaded.

Questions
What is a good reaction time?
Around 200 to 270 ms is typical for a visual reaction on a computer. Treat it as a rough guide: devices and screens add their own delay.
Why do my scores change a lot?
Reaction times vary from tap to tap with focus, tiredness and the device. The five-attempt average smooths this out.
What happens if I tap too early?
The attempt is cancelled, with no penalty, and you tap again to restart it.
Is my best score saved?
