## About ReactionMetric

ReactionMetric is a free browser-based reaction-time benchmark. Users complete repeatable five-trial sessions and receive median, best and consistency results, with supporting context about browser/device measurement. The core test works without mandatory signup. It is intended for people who want a repeatable visual reaction baseline. A short session gives several results to compare rather than relying on a single attempt. Results reflect browser-observed timing and can be affected by the browser, display and input device. The test is not a clinical assessment or a substitute for sport-specific skills.
