Understand how factors like device latency, browser performance, and your own focus can affect your score. This tool is ideal for gamers, athletes, or anyone looking to quickly check their focus and response speed. Use the results as a practical benchmark for your own performance, not as a medical measurement.

Key features include:

• Randomized waiting periods to prevent prediction.
• Clear display of results in milliseconds.
• Tracking of multiple attempts to identify trends.
• Guidance on interpreting scores and factors influencing reaction time.
• Use cases for gaming, sports warmups, classroom experiments, and focus checks.

Improve your reaction speed by practicing consistently, comparing averages, removing distractions, and using the same setup for each test session.
