How the Test Works

  1. 1.

    Press start. The panel turns red — wait, and don't click yet.

  2. 2.

    After a random delay (2–5 seconds), the panel turns green.

  3. 3.

    Click, tap, or press Space the instant you see green.

  4. 4.

    Clicking early is a false start: that attempt doesn't count, so wait for green.

  5. 5.

    Complete five attempts to get your median score, best click, and percentile.

About the Reaction Time Test

This reaction time test measures how quickly you respond to a visual signal. Press start, wait for the red panel to turn green, and click the moment it changes. The delay before each change is random, so you can't anticipate it — you have to actually react.

You get five attempts per run, and your score is the median of the five, shown alongside your single best click. The median matters: anyone can get one lucky 180 ms click, but the median is a stable measure of your real speed. Most people land between 200 and 300 milliseconds; anything under 200 ms is genuinely fast.

Your times are affected by more than your nervous system. Monitor refresh rate, input lag, and whether you're on a phone or a laptop trackpad all shift results by tens of milliseconds — which is why we track mobile and desktop personal bests separately, and why comparing runs on the same device tells you the most.

When you're done here, try the other benchmarks: the choice reaction test adds a decision to every click, the audio reaction test swaps your eyes for your ears, the aim trainer measures speed and precision together, and the daily challenge gives everyone the same seeded gauntlet once a day. See how your median stacks up against average reaction time by age and device, or browse all six tests.

Features

  • Five-attempt scoring

    Median and best of five attempts — one lucky click never inflates your score.

  • Six benchmark tests

    Reaction, choice, audio, aim, sequence memory, and clicks per second.

  • A daily challenge

    One seeded gauntlet per day — the same for everyone, with streaks and a permanent archive.

  • Percentiles and history

    See how you compare, and track your personal bests per device over time.

FAQ

For a visual click test, the typical median is around 250–280 milliseconds. Under 230 ms is quick, under 200 ms is genuinely fast, and consistent sub-180 ms medians are rare — usually gamers or athletes on fast hardware.

A single attempt is noisy — one lucky guess or one lapse can swing it by 100 ms. The median of five attempts throws away the outliers and measures the speed you can actually repeat.

That's a false start: the attempt is discarded and you retry it. Guessing the timing would defeat the point of the test, so early clicks never count toward your score.

Touchscreens, mice, and trackpads have different input latency, and screens differ in refresh rate. That's hardware, not reflexes — which is why the site tracks a separate personal best per device.

Somewhat. Sleep, caffeine timing, and practice on the specific task each shave off real milliseconds, and warmed-up runs beat cold ones. Raw simple reaction speed is mostly physiological, but your consistency and choice-reaction speed respond well to training.

Once a day there's a seeded challenge — the same sequence of rounds for every player. Finish it to keep your streak, and every past day stays playable in the archive.
