Jitter click test, how fast can you click?

A jitter click test counts how fast you can click when you use jitter clicking, a technique where you tense your arm so your hand vibrates and the mouse button is pressed many times a second. Pick a time from 5 to 60 seconds, then click the pad. The clock starts with your first click. At the end you get the total clicks, the clicks a second, the best one-second window, the best and worst second, and a bar for every second so you can see where you sped up or tired.

How to use the jitter click test

1. Pick a length under Time: 5 s, 10 s, 15 s, 30 s or 60 s.
2. Pick which button to count under Count clicks from: Any, Left or Right. Right-click does not open a menu on the pad.
3. Click the big pad to start. The pad shows your count and the time left.
4. When the time is up, read the cards and the bars. Your best for that length is saved in this browser.
5. Click the pad again to go for a better round, or press Start over to clear the result.

What the numbers mean

Average speed is clicks divided by seconds. 74 clicks in 10 seconds is 7.4 clicks a second. Best one-second window slides a 1000 ms window across your clicks and keeps the highest count. It is always as high as, or higher than, your best clock second, because it is free to start at any click.

Stamina compares the clicks in the last half of the round with the first half. If you made 40 clicks in the first 5 seconds and 34 in the last 5 seconds, the stamina is 34 / 40 = 85%. Stamina shows for rounds of 10 seconds or longer.

The table only shows the sum, clicks divided by seconds, with made-up counts. Longer rounds tend to give a lower rate because a vibrating hand tires, which is what the per-second bars and the stamina card are for.

How this differs from other click tests

• The mouse click test checks each button and finds a worn switch that double clicks by itself. Use it to test the mouse.
• The click counter is a tally with no time limit. Use it to count things.
• This page is for speed, with longer rounds, a left or right choice, the best one-second window and the stamina card.

Limits and safety

The page counts the clicks your browser receives. If your mouse, driver or system merges very fast clicks, the page cannot see them. Games and sites can also set their own limits. Jitter clicking puts strain on the hand and forearm, so rest between rounds and stop if anything hurts.

For a keyboard version, try the spacebar counter. To train aim as well as speed, use the aim trainer.
