Working in ten-minute blocks
Ten minutes is a small enough commitment to start a task you've been avoiding, and long enough to get something real done. This page is set up for doing that more than once: name the block, press Start, and when it ends either stop or press Another 10 to log it and keep going. For longer stretches with breaks between them, try the 25-minute focus and break timer.
The two warnings help you finish cleanly rather than mid-sentence. At 5 minutes left you hear a soft two-note sound and the face says so; at 1 minute left you hear it again, which is your cue to wrap up the current step and jot down where you'll pick up. Both can be switched off.
The log under the options lists each finished block with the time it ended and what you named it, plus a running total for the day. It's a simple record, kept only on your device, of how many blocks you got through.
How to use the 10 minute timer
- Optionally type what the block is for. It shows above the digits and in the tab title.
- Press Start. Warnings come at 5:00 and 1:00 left unless you turn them off.
- When the alarm sounds, press Stop to finish, or Another 10 to log the block and start the next.
- Check today's log below the options for how many blocks you've done.
Ten minutes of reading
A ten-minute block suits reading a chapter section, a long article, or a few pages of a textbook. Put the page number or chapter in the block name, for example Ch. 4 from p. 81, so the log doubles as a bookmark. Use the 1-minute warning to finish the paragraph you're on rather than stopping mid-thought.
For reading aloud with a child or a class, Full screen shows the ring and its minute marks large enough to see from a reading corner, and you can leave the warnings on so listeners know the end is coming. A teacher running several activities in a row may prefer the projector timer for a class.
A short workout or a timed tidy
Ten minutes also fits a short home workout or a quick reset of the house. For a tidy, the 5-minute warning is a natural point to move to the next room. For a workout made of ten one-minute moves, the minute marks show where each move changes, though if you want a beep at every change the 1 minute timer with 10 rounds does that for you. For short, hard intervals instead, what Tabata is and how to time it explains the 20/10 format.
Either way, the alarm repeats until you press Stop by default, since you may not be standing next to the screen when it goes.
Leaving it running in another tab
Ten minutes is long enough that you'll probably switch tabs, and that matters. Google's Chrome documentation explains that once a page has been hidden for more than five minutes, Chrome may check its chained timers only once per minute. A countdown that adds up ticks could then fall behind and ring late.
This timer doesn't count ticks. It stores the moment the block will end, puts the 5-minute warning, 1-minute warning and alarm on the browser's audio clock when you press Start, and recalculates the moment you come back to the tab. The tab title also shows the time left, so you can see it from your other tab.

Ten-minute block questions
What does Another 10 do?
When a block ends, Another 10 silences the alarm, adds the block to today's log and starts the next ten minutes straight away. It's one tap, so you don't lose your place deciding whether to carry on.
Where is the block log kept, and when does it clear?
Only in this browser, on this device. Nothing is sent anywhere. It keeps the current day's blocks and starts fresh the first time you open the page on a new day, or sooner if you press Clear today's log.
Can I turn off the 5-minute and 1-minute warnings?
Yes. Untick either one before you press Start. With both off you get a plain ten-minute countdown with just the end alarm.
Will it ring on time if I switch to another tab for the whole ten minutes?
It should. The warnings and alarm are booked on the browser's audio clock when you press Start, and the time left is worked out from the stored end time when you come back; Leaving it running in another tab, above, explains why that matters.
What are the small marks around the ring?
One mark per minute. As the ring shrinks past each one you can see roughly how many minutes are left from across the room, without reading the digits.
Can I set 10 minutes and 30 seconds?
Not on this page, which is fixed at ten minutes so it starts in one tap. For that, use the countdown that takes any length.

The 10 minute timer is one of Cedrick Reese's TimerCalculator.com tools. Its block log is written to this browser's own storage, keeps one day at a time, and is never uploaded. Its launch testing used a simulated clock in an automated browser. A full block had to show Under 5 minutes at 5:00, Last minute at 1:00 and the alarm at 0:00, Another 10 had to log the finished block and start the next, and the log had to survive a reload and come back empty the following day. If storage is blocked, the log still works until you close the page.
