Ten minutes, counting down. Press Start, or tap the space bar.
Ten minutes is the length of a bounded attempt. It is the timebox people put around a meeting item that would otherwise eat the hour, around a tidy-up, around a task they are avoiding on the theory that ten minutes of it is survivable. That last one works often enough to be worth the timer.
It is also long enough that you will forget it is running, which is the argument for a countdown over a glance at the clock: a countdown interrupts you, and a clock waits to be consulted by someone who is no longer thinking about it.
Other lengths are a matter of typing them in. There is a five minute timer, a twenty minute timer, and a twenty-five minute focus timer is the block that idea is usually built around.
How to use it
- Press Start, or the space bar, and the countdown begins.
- Leave the tab open. It keeps time whether or not you are looking at it.
- Change the minutes and seconds in the boxes for any other length.
Questions
What is a ten minute timer good for?
Timeboxing, mostly: an agenda item, a tidy-up, or a task you are putting off, on the reasoning that ten minutes of anything is bearable. It is also the standard length for a short break in most focus routines, which put one after every fourth working stretch.
Can I pause it?
Yes, Start becomes Stop while it is running, and the space bar does the same thing. Resetting puts the full ten minutes back rather than resuming, so pause when you mean to continue and reset when you mean to start again.
Does the timer keep running if I switch tabs?
Yes. The count comes from the clock rather than from a tick that a background tab would slow down, so it is right when you come back however long you were away. Closing the tab does end it, since nothing is stored anywhere.
Will it make a sound when it finishes?
It rings at zero. Browsers block sound until a page has been interacted with, and pressing Start counts, so a timer you started will always be able to ring. Check the tab is not muted if you hear nothing.
Is anything sent anywhere?
No. The timer is arithmetic on your own clock, running in this tab, and the page makes no request of its own. It works with the network off and keeps no record of what you timed.
Other lengths
The same timer on a different duration. Any of them takes a length of your own once you are there.
