Click to start 5 rounds — react when the box turns green

How to play
- Click the box to begin the first round.

- The instant it turns green, click as fast as you possibly can.
- Your time is recorded in milliseconds. After 5 rounds you get your average — beat it next time.
Frequently asked questions
What is a good reaction time?
For simple visual reactions, most people land between 200 and 300 milliseconds, and roughly 250 ms is a typical adult score. Anything under 200 ms is excellent, and elite esports players and athletes often average 150–200 ms.
Why is the delay before green random?
The 1–5 second random wait prevents you from anticipating the signal. If the delay were fixed, you would be measuring rhythm and guessing rather than your true reaction to the visual stimulus.
Does age affect reaction time?
Yes. Reaction time typically peaks in your late teens and twenties and slows gradually afterwards — but sleep, fitness and familiarity with the test all move the number significantly, so age is far from destiny.
Can I improve my reaction time?
You can sharpen it. Consistent sleep, regular cardio exercise and simply practising response tasks all help. Compare your scores under the same conditions — same device, same time of day — to track real progress.
Why do I get different results on my phone?
Touchscreens add latency: the digitizer, the refresh rate and even your finger size change when the tap registers. Results are comparable within the same device, so track your personal best per device instead of across devices.
