Is Reaction Time Test Worth It? FAQ & Reviews
The test uses JavaScript's high-precision Performance API for millisecond-level timing. However, device performance, browser type, and network latency may have slight effects. We recommend multiple tests for average results.
Average adult visual reaction time is about 200-300ms. Professional athletes or esports players may achieve 150-200ms. Age, fatigue, and attention affect reaction time.
This is called 'anticipation error'. When you're overly focused or trying to predict when green appears, you may unconsciously click early. Stay relaxed and focus on the color change rather than time prediction.
Yes, our test fully supports touchscreen devices. Touch reactions are usually slightly faster than mouse clicks. Regardless of device, maintain consistent test conditions for valid self-comparison.
