# Reaction-time game

Canonical page: https://nepocore.com/tools/reaction-test/

Measure the delay between a visual cue and your click or tap. This browser tool shows the inputs, assumptions and resulting output so you can use it for a specific everyday task.

## How to use it

1. Enter your own values or choose a supported file.
2. Adjust the options and run the tool.
3. Review the result, then copy, export or save it when available.

## Example

Wait until the panel changes color, then tap it and compare several attempts.

## Limits and checks

Display refresh rate, device latency and input hardware affect the measurement. It is a casual game, not a neurological or medical test.

## Access and processing

Free to use without an account. Interactive processing requires JavaScript in a modern browser. Input is processed in the browser rather than sent to a processing server. Optional browser storage is not a synchronized account.
