One site, six ways to measure speed
Each test isolates a different link in the chain between a signal and your response. The reaction time test is the baseline — pure signal-to-click speed. The choice reaction test adds a decision, the audio test swaps the signal from eyes to ears, and the aim trainer adds pointer travel and precision. The sequence memory test steps away from speed entirely to measure working memory, and the CPS test strips everything back to raw click cadence.
Scores are stored on your device only, split by mobile and desktop because input hardware genuinely changes the numbers. Every result shows a percentile against reference benchmarks — see average reaction time for the full distributions.
