Sub-millisecond Timing
Uses performance.now() for high-precision timing, measuring from the exact moment the screen turns green to your click, accounting for browser rendering latency. Want to benchmark your start-line reflexes against racing lights? Try our f1 reaction time test.
False Start Detection
Clicking before the green signal is detected and the round is automatically voided. False starts are logged separately so you can see your anticipation rate. If you're curious how fast you can click overall, test our visual reaction.
5-Round Averaging
Each test averages 5 rounds to give a statistically stable result. Outliers from nerves or distraction have less impact than a single-attempt test. Pair this with our input lag and aim training for a fuller picture of your reaction chain and precision.
Touch Optimised
Works on mobile and tablet with touch events. Tap the zone when it turns green. Display latency on phones may add ~20–30ms to your results. You can also verify your display's refresh rate test.
Frequently Asked Questions
The typical human visual reaction time averages between 200ms and 250ms on standard displays. Competitive esports players frequently score between 150ms and 200ms. Scores below 150ms represent elite-tier reflexes or high-refresh hardware optimization.
A standard 60Hz display introduces up to 16.7ms of frame buffer delay. Upgrading to a 144Hz or 240Hz monitor lowers this display latency to 4–7ms. A wired 1000Hz gaming mouse adds under 1ms, whereas Bluetooth peripherals can introduce 15–30ms of lag.
Auditory stimuli reach the brainstem via the auditory nerve in roughly 8–10ms, whereas phototransduction and retinal processing take 20–40ms. As a result, humans consistently react 30–50ms faster to audio cues than visual signals.
Getting 7–8 hours of quality sleep, performing 10–15 minutes of daily reflex drills, staying hydrated, and doing a 2–3 round warm-up before measuring improves reaction speed by 20–40ms.
