Fast reaction times are crucial for competitive gaming. Top gamers typically have reaction times under 200ms.
Athletes use reaction time tests to improve their performance and measure their progress over time.
Reaction time is a key indicator of cognitive health and can help monitor mental alertness.
The average human reaction time is 250ms to visual stimuli. Professional gamers and athletes often achieve times between 150-200ms.
Regular practice, proper rest, and maintaining focus during the test can help improve your scores. Try testing at different times of day to find your peak performance period.
Our test measures reaction times with millisecond precision. However, results can be affected by your device's display lag and input latency.
