The standard short break
Five minutes is the break length the Pomodoro technique specifies between focus blocks, and it has stuck for a reason: it is long enough to stand up, look at something further than an arm away, and drink something, but too short to start anything that will hold you.
The failure mode of a break is not that it is too short. It is that it never ends. Opening a feed or a message thread turns five minutes into twenty-five with no clear moment where that happened. A countdown removes the decision — you are not judging when to go back, you are waiting for a sound.
Other things that fit in five
The other use for a five-minute timer is as a lever against procrastination. Committing to five minutes of a task you have been circling is small enough that refusing it feels ridiculous, and starting is almost always the hard part. Frequently you keep going once the timer ends — but the deal was five minutes, and you are allowed to stop.
- A break between focus blocks
- Getting started on something you have been putting off
- A short breathing or stretching pause
- Boxing a message or an email so it does not expand
- Tea, coffee, and anything else with a steeping time
Using it here
Press start and the countdown runs on its own. If you want sound with it, pick anything from the library below — the timer and the audio run independently, and by default playback stops when the countdown reaches zero.
If you are running five-minute breaks as part of a work cycle, the Pomodoro timer handles the whole loop for you, including switching the background sound between focus and break.
Common questions
Does the timer keep running if I switch tabs?
The countdown keeps running. Audio may be suspended by the browser in a background tab on some devices, particularly mobile, so keep the tab visible if you want the sound to continue.
Will it make a sound when it finishes?
The plain timer stops playback at zero rather than chiming. The Pomodoro timer plays a two-tone chime at each phase change, so use that if you want an audible end.
Can I change the length after starting?
Yes. Pick a different preset while it is running and the elapsed time carries over to the new length.
