How to use the aim and reaction time test
- On the "Reaction time" tab, click the blue screen and it turns red. Click as fast as you can the moment it turns green. Clicking before green is a false start.
- Up to ten results are kept, and the average, best, median and a rating are shown.
- On the "Target aim" tab choose the number and size of targets, start, and click each target as it appears. At the end you get the average time and accuracy.
How it is measured and read
Reaction mode records the moment the screen turns green and computes the difference to the click in milliseconds (ms). The wait before green is random between 1 and 4 seconds so you cannot time it in advance. The median is less shaken by one or two outliers, so look at it together with the average.
Target mode measures the time from when a target appears until you hit it, and combines missed clicks to compute accuracy (hits ÷ total clicks). Smaller targets tend to worsen both accuracy and time. Finding the balance between the two is the heart of aim practice, because pushing speed alone adds misses and can make the whole run slower.
What affects the result and how to practice
A measurement includes more than your own reaction: screen refresh rate (a 60 Hz screen frame is about 16 ms), monitor response delay, how the mouse is connected and browser processing time. So the same person getting different numbers on another device is normal, and the records here are best used to see change on the same device.
Good sleep, sensible caffeine use, a comfortable posture and repetition help your reaction. For aim, using your whole arm rather than only the wrist and tuning mouse sensitivity matter. Doing it too long in a row tires your wrist and eyes, so take breaks.
Things to know when measuring
- Look at the average and median of five to ten attempts.
- Compare on the same device and in the same posture.
- Stop and rest if your wrist hurts.
- If you are sensitive to flashing bright screens, use with care.
FAQ
What is the average human reaction time?
The average time to react to a visual cue with a click is usually said to be between 200 and 300 ms. It varies a lot with age, condition, focus and device, and the average and median of many attempts are more reliable than a single result.
My results change every time even though I am the same person.
That is normal. The waiting time is random and your response changes with focus and expectation. Look at the average and median of five to ten attempts. Very fast clicks may be guesses, so interpret them separately.
Can I compare phone and PC results?
Not directly. Refresh rate, touch processing delay and how the mouse is connected differ, so the same person can differ by tens of milliseconds between devices. It is best used to see change over time on the same device.
