Results depend on your device, display refresh rate, input lag and browser. The percentile is an approximation based on typical published reaction times, not a medical measurement.
Check your clicks per second: click the box or press Space as fast as you can for 1, 3, 5, 10, 30 or 60 seconds. The timer starts on your first click, and you get your CPS, total clicks, peak speed and a per-second chart, with your best score saved for each duration. Works with a mouse, a touch screen or the keyboard.
How to use
- Reaction: tap the box, wait while it is gray, then tap as soon as it turns purple. Five tries give your average.
- Tapping before the color changes is a false start: that try is repeated.
- CPS: pick a duration, then click the box or press Space as fast as you can. The timer starts with your first click.
- Aim: choose 30 targets, 60 seconds or Precision and tap the targets as quickly and accurately as you can.
- Tap a result row to copy it. Your history and best scores stay in this browser.
- Typical simple reaction times to a visual signal are around 200–300 ms. The percentile assumes an average of about 270 ms and is only a rough guide.
- Displays add delay: a 60 Hz screen can add up to about 16 ms, and wireless mice or touch screens can add more. Compare results on the same device.
- The test pauses or resets when you switch tabs, so background time never counts.
- In 60 seconds mode targets shrink and disappear after about 1.7 s; in Precision the targets are small and accuracy matters most.
How CPS is measured
CPS is total clicks divided by the test time: 40 clicks in 5 seconds is 8 CPS, 100 clicks in 10 seconds is 10 CPS. Peak shows your fastest moment, the most clicks inside any one-second window, which is usually higher than your average because speed drops as your finger tires. Longer tests, 30 or 60 seconds, measure endurance more than burst speed.
A normal click with one finger usually lands somewhere around 5 to 8 CPS. Techniques such as jitter clicking (tensing the arm to vibrate the finger) or butterfly clicking (alternating two fingers on one button) can go well above 10.
Tips for a better score
Rest your wrist on the desk and click with the fingertip rather than the whole finger. A mouse with light, short-travel switches helps, as does a hard, flat surface for touch screens. Warm up first, and don't hold tension for long sessions: if your hand or wrist hurts, stop. Some mice debounce clicks in firmware, which can cap very fast clicking.
Frequently asked questions
What is a good CPS score?
Around 6 to 8 CPS is typical for normal clicking. 10 or more is fast and usually needs jitter or butterfly clicking.
How is CPS calculated?
Total clicks divided by seconds. 50 clicks in a 5-second test is 10 CPS.
Can I use the Space bar?
Yes. Pressing Space counts as a click, and the timer starts with your first press or click.
Which test length should I use?
5 seconds is the standard test. 10 seconds gives a steadier average, and 30 or 60 seconds tests endurance.
Is jitter clicking safe?
Short sessions are fine for most people, but holding tension for long can strain the wrist and forearm. Stop if it hurts.
