Click speed test

How clicks per second is calculated

It is the number of clicks in the 10 seconds divided by 10. Click 74 times and that is 7.4 per second. Stopping early does not shorten the divisor — it stays 10 seconds, because otherwise someone who stopped early would look faster and no two runs could be compared.

When does the counting start

Press start and a 3·2·1 countdown runs; the 10 seconds begin the moment it reaches 0. Clicks during the countdown are not counted, so you can rest your finger and wait. If counting began on the press itself, the time spent moving to the button would sit inside the 10 seconds and the same person would score differently every run.

For a moment after time is up, clicking does not start a new round. Your hand keeps going at the end, and without that pause you would be in the next round before seeing the result. When the note reads "click to go again", you can.

Phone or computer — which is better

A screen you can alternate two fingers on usually scores higher. A mouse takes one finger, so it gives up ground. Different hardware means different conditions, which is why comparing your own runs on one device is the comparison that holds.

Where the record is kept

Only your highest count is kept, in this browser's storage. It is not sent to a server and it is not ranked against anyone else. If storage is blocked, the best score is the only thing lost — the test itself still runs.

How is the share link built

Share puts the numbers into the address and builds a link. Opening that link fills the same card with those numbers, and the person who opened it can start their own round right away. Building a link sends nothing anywhere, it only writes an address.

The address is scrambled so the values are not readable, and changing one character stops the numbers from showing. That catches links garbled in transit or edited by hand. It does not confirm who measured the value, or when.
