Stopwatch
One square digital clock, two modes. Count up and mark laps, or set a time attack and count down.
This lap 00:00.00
Ready
Space starts and pauses. L marks a lap. R resets. M is the sound.
No laps yet. Start the timer, then mark a split.
Why this exists
A gym set, a speaking slot, or one step in a recipe often leads to installing a timer. This page is the timer.
The clock that counts up and the time attack that counts down share one screen. There is no account.

01How to use it
On the stopwatch, press Start. The same button pauses and then continues. The left button marks a lap while it runs, and resets while it is paused.
For a time attack, pick 30 seconds, 1, 3, 5, or 10 minutes, or type minutes and seconds. While it runs, the left button adds fifteen seconds.
The screen stays awake during a run. Sound turns off with M or the sound button.

02What you get
Two laps show each split and the total. The shorter one is marked fastest and the longer one slowest.
A one-minute time attack counts down from 60. The bar is what is left, and the clock rings at zero. Again runs that same time once more.

03Worth knowing
It does not add one tick at a time. It shows the difference on the browser’s precise clock, so a sleeping tab still keeps the elapsed time.
The lap list lives in this tab. Reset or a reload clears it. It is not stored on a server.
Reset clears the face and the laps only when you ask. On a time attack, reset returns to the time you set.
There is no sign-in and no install. A phone uses the same page.
Questions
- QDoes this need an account or an install?
- ANo. After the page has loaded, the timer runs in the browser.
- QWill the time stop if I switch apps?
- AThe animation pauses. The elapsed time is computed again from the start, so the face catches up when you return.
- QWhat is the time attack?
- AA countdown. You set the length, start it, and it rings at zero. You can add fifteen seconds while it runs.
- QCan I save the laps?
- AThey stay on this page until you reset or reload. They are not stored on a server.
