Reaction Time Test
Wait for the signal, respond as fast as you can, and get a five-trial median, best score and consistency.
Click to begin
Wait for green, then click or tap as fast as you can. Early responses do not count.

Your browser and device are part of the timing. We do not guess away hardware delay.
Your setup changes the number
Your display, input method and system can shift the result. ReactionMetric uses the closest comparison with enough real results.
One lucky click is not your reaction time
ReactionMetric also reports your best result and consistency so you can separate a repeatable baseline from one exceptional click.
Test a different kind of speed
Keyboard Reaction Test
React to a visual signal with Space, Enter or another normal key across five valid trials.
Sound Reaction Test
React to a browser-generated tone across five valid trials and compare your local audio median with visual reaction history.
F1 Reaction Test
Face a five-red-light start sequence across five valid launches, with false-start tracking, median and consistency.
Double Click Test
Check for accidental rapid repeat events with guided single-click sampling, button lock and interval evidence.
CPS Test
Measure clicks per second across 1, 5, 10, 30 and 60 second modes, with peak speed, consistency and local personal bests.
Visual Reflex Test
Find the green target among distractors and measure a different visual-response task.

Reaction time test FAQ
Is 200 ms reaction time slow?
A 200 ms browser result is fast in many common visual reaction tasks, but the number depends on the task and your device. Compare the same protocol and setup rather than treating one universal cutoff as clinical truth.
Is 170 ms a good reaction time?
170 ms is a very quick browser-observed result for a simple visual click task. Repeat several trials and check consistency before judging yourself from one attempt.
Is a 100 ms reaction time possible?
100 ms is at the extreme edge of a simple visual response. ReactionMetric treats responses below 100 ms as anticipatory and excludes them from valid trials. Scores at or just above 100 ms should still be interpreted cautiously because anticipation, display timing, input hardware and task design all matter.
Does a higher refresh-rate monitor improve a reaction time test?
A higher refresh rate can reduce the time between a browser scheduling a visual change and a new frame appearing, but it does not directly make your nervous system faster. That is why ReactionMetric records refresh-rate context instead of “correcting” your score.
Is this the same as a reflex test?
Not exactly. This page measures a simple visual reaction-time task. Our Visual Reflex Test is a separate browser task; neither is a clinical tendon or neurological reflex examination.
