About This Tool
The Reaction Time Test is a simple and fun tool to measure your brain's response time to visual stimuli. The average human visual reaction time is about 250 milliseconds, with most people falling in the 200-300 ms range. Through repeated practice, you can understand your physiological limits and try to break records. The tool supports automatic averaging and median calculation across multiple attempts for more accurate results.
