About Us

Welcome to the Reaction Time Test

Reaction Time Test provides a simple and accessible way to measure your visual response speed directly in your browser. Our tool records how quickly you respond after a visual signal appears and displays the result in milliseconds.

Who Runs This Website?

Reaction Time Test is maintained by Austin, the author behind our guides. The website focuses on browser-based reaction-time testing and clear educational information about reaction speed, device latency, testing conditions, and result interpretation.

Our Purpose

Our goal is to make reaction-time testing easy to understand and available to everyone. Whether you are a casual user, gamer, student, teacher, athlete, or someone tracking personal performance, you can complete five attempts and review your average, best score, median, and consistency.

Simple, Private, and Accessible

The Reaction Time Test is free to use and does not require registration. When the history feature is enabled, completed sessions are stored locally in your browser. Your saved results are not automatically uploaded or shared with us.

Understanding Your Results

Reaction-time scores can be affected by attention, tiredness, practice, monitor refresh rate, mouse or touchscreen latency, browser performance, and other device-related factors. For more meaningful comparisons, complete multiple attempts under similar conditions.

General Information Notice

Our Reaction Time Test is designed for general information, personal practice, and informal educational demonstrations. It is not a medical or diagnostic tool and should not be used to determine driving fitness, professional ability, employment suitability, athletic performance, or any health condition.
