How Fast Are Your Reflexes?
Measure your visual reaction time across 5 rounds. Wait for the color change, click as fast as you can, and see your average response time — all processed locally in your browser.
This test measures visual reaction time by recording the delay between a color-change stimulus and your click response, timed with performance.now() at sub-millisecond precision across 5 rounds.
The average human visual reaction time is 200–250ms; competitive esports players consistently achieve under 150ms.
What Do Your Results Mean?
| Result | Range | Meaning |
|---|---|---|
| Good | Under 200ms average | Your reaction time is faster than average. Scores under 150ms place you in the competitive gaming range — excellent for FPS and rhythm games. |
| Warning | 200–300ms average | This is a typical human reaction time. Fatigue, age, and display latency all contribute — test under consistent conditions for reliable comparisons. |
| Bad | Over 300ms average | Slower than average — could indicate fatigue, high display latency, input lag from wireless peripherals, or simply unfamiliarity with the test. Try again when alert. |
Common Issues and How to Fix Them
Reaction time scores seem inconsistent across rounds
Random delays between 2–5 seconds prevent anticipation. Outliers often come from brief lapses in attention. Focus on the screen steadily and discard your worst round mentally.
Scores are higher than expected on a known-fast setup
Close background tabs and apps that consume CPU. A 60Hz monitor adds up to 16.7ms of display latency versus 6.9ms on a 144Hz display. Wireless mice add 1–4ms compared to wired.
