Click as fast as you can and see your reaction time in milliseconds
The Reaction Time Test is a scientifically designed tool that measures how quickly you respond to visual or sound-based stimuli. It helps you evaluate your average reaction time, hand–eye coordination, and processing speed. Whether you're testing your performance for gaming, sports, driving, or cognitive training, this tool gives you accurate results in just a few seconds.
Our online test is inspired by widely used benchmarks — including F1 reaction time tests, human performance studies, and popular reaction games — making it suitable for users worldwide who want reliable, real-time reaction measurement. Try the Free Reaction Time Test for instant speed tracking.
Click the target as soon as it appears and the tool will calculate your reaction time instantly. You can see your last, average, and best reaction times after each test.
A reaction time test measures how long it takes for you to respond once a visual or auditory signal appears. The faster you react, the lower your reaction time in milliseconds (ms). This tool supports:
It delivers precise timing, making it ideal for performance evaluation and skill improvement.

👤 General Users
A fun and interactive way to evaluate your mental sharpness and reflex ability.
1. What is a good average reaction time?
Most adults have an average reaction time between 200–250 ms. Athletes and trained individuals may react faster, while beginners may score slightly higher.
2. Does the Reaction Time Test work on mobile devices?
Yes. The test is fully optimized for mobile and supports tap-based input, making it easy to check your reaction speed anywhere.
3. How accurate is the F1-style reaction test?
The F1 mode uses light-based triggers similar to motorsport testing, offering high precision and realistic timing to simulate actual F1 reflex challenges.
4. Can I test my reaction time with the spacebar?
Yes. The tool includes a spacebar reaction mode, allowing keyboard-based testing similar to gaming environments.
5. What is the fastest reaction time recorded?
Some professional athletes and experiment participants have measured reaction times below 100 ms, but such scores are extremely rare and often require specialized equipment.
