This is a simple tool to measure your reaction time (measured in milliseconds).

It is interesting to note, as per collected data so far by the author of this tool, the average (median) reaction time is 215 milliseconds. I just tried it 28 times and my results has shown below. The best i could recorded was 168 milliseconds. But it has been mentioned that some people were manage to react within 100 million seconds.

Here are few important tips given in the website to improve your reaction time when taking a test with that tool. These tips are posted by the users who reacted within 100 milliseconds.

Don’t concentrate on the text. If you read “click,” your brain is taking too much time to read before reacting. Don’t focus too hard in one spot, use more peripheral vision (still looking at the box), and just click when “something” changes. Alcohol and some medicine hurt your score.
- Argammon

Sit close to the monitor. Find the spot on your mouse directly above the spring, and press down so you are just on the threshold of clicking.
- Nitro

Minimize distractions. Stay hydrated and play when you’re already alert.
- HitMe

Concentrate as much as possible. Play lots of video games.
