About the tools
About FPSReaction
FPSReaction offers free browser-based reaction time and aim practice tools with clear, practical context for each result.
How the Tests Work
The tests run locally in the browser. They use your device and browser to present a visual task, record interactions, and show the result during the same session.
Measurement Limits
These are practical browser tests, not laboratory measurements. Display refresh rate, input hardware, browser scheduling, device performance, attention, and fatigue can affect a result.
Our Approach
We aim to make the rules and limitations understandable. FPSReaction is not officially affiliated with or certified by game publishers or esports federations.
