Rings until stoppedOn a phone the big digits sit above the settings, and Start, Pause and Reset are in the bar at the bottom of the screen.
Tap a preset or set a custom time up to 99 hours. Pause, resume, reset, or add a minute with +1 min while it runs.
Start, stop and press Lap. Each lap shows its own split and the running total; Copy laps pastes into a spreadsheet.
Pick a date and time (or a holiday) and see days, hours, minutes and seconds left. Copy the link to share it.
25 minutes of focus, then a 5 minute break; after four focus blocks, a 15 minute break. Change any length.
Browsers slow down pages you aren't looking at. This timer is built so that never changes the time it shows.
MDN explains that browsers "enforce a minimum timeout delay in inactive tabs". Chrome checks such timers once per second, and after a tab has been hidden and silent for a while, only once per minute.
When you press Start, the tool notes the clock time it should end. Every update works out "end time minus now", so a late or skipped update never loses a second.
The alarm tone is scheduled on the browser's audio clock for the end time, so it plays on time even when the page's timers are slowed. It rings until you stop it.
While a timer runs, the page asks for a Screen Wake Lock so the screen doesn't dim or lock. MDN notes the lock is released when the page is hidden and may be refused in power save mode or on low battery; the timer still keeps time either way, it just can't keep your screen awake.
Pick the one that matches the question you are asking.
Counts down a set length and rings at zero. Best for cooking, workouts, tests and anything with a fixed time.
Counts up from zero in hundredths of a second, with laps. Best for runs, swims, speeches and timing a task.
Shows days, hours, minutes and seconds to a date and time, and counts up once it has passed.
Alternates focus blocks and breaks, with a longer break after a set of focus blocks, and counts the sessions.
The clock is the same. What changes is what you are timing.
Put a big full screen timer on the board for a quiz, group work or clean-up time, so everyone can see it.
Name the timer (pasta, eggs, rice) and keep it running in a tab while you read a recipe in another.
Time laps on the track or in the pool, then copy the splits into a training log.
Work in focus blocks with short breaks, and count how many you finished today.
With the default lengths, a set of 4 focus blocks and their breaks takes 130 minutes (2 h 10 min).
| Block | Phase | Length | Clock time |
|---|---|---|---|
| 1 | Focus | 25 min | 0 to 25 min |
| 2 | Short break | 5 min | 25 to 30 min |
| 3 | Focus | 25 min | 30 to 55 min |
| 4 | Short break | 5 min | 55 to 60 min |
| 5 | Focus | 25 min | 60 to 85 min |
| 6 | Short break | 5 min | 85 to 90 min |
| 7 | Focus | 25 min | 90 to 115 min |
| 8 | Long break | 15 min | 115 to 130 min |
Change any length in the Pomodoro settings: focus from 1 to 120 minutes, and the long break after 2 to 8 focus blocks. Turn off "Start the next phase by itself" to start each block by hand.
Both count down. They answer different questions.
Ten minutes from now, whenever now is. Pause it, add a minute, and it rings when the time is used up.
A fixed date and time that doesn't move. Share the link and everyone counts to the same moment in their own time zone.
Small habits that make a timer easier to use.
Space starts and stops the timer, stopwatch or Pomodoro while the timer is on screen.
Press L for a stopwatch lap and R to reset. Keys are ignored while you type in a box.
Huge digits fill the screen. Press F or Esc to leave full screen.
Press Test next to the volume before a long timer, so the alarm isn't a surprise.
A notification appears when time is up and the tab is hidden, if you allow it.
The link carries the date, time zone and name, and opens straight to the countdown.
A name like Pasta shows on the timer and in the tab title, handy with several tabs.
A running timer keeps going after a reload; one that ended while closed shows when it finished.
A phone that locks its screen may stop a web page, so the alarm can be late or silent until you unlock it. For a timer you can't miss, keep the page open on screen (it asks to keep the screen on) or use your phone's built-in clock app.
