Start a countdown timer with a sound, run a stopwatch with laps, or work in Pomodoro intervals. Everything runs in the browser — even when the tab is in the background.

If the tab is minimised the sound alone may not be enough — turn the notification on.

About the timer
A timer, a stopwatch and Pomodoro are three ways of working with time. A timer counts a set interval down to zero and signals; a stopwatch counts up and records splits; Pomodoro alternates work and rest to help you concentrate. A fourth mode, interval, alternates work and rest by rounds for training. All of it runs in the browser, needs no installation and does not drift when the tab is minimised.
Countdown timer
Counts down
25:00 → 00:00
Set an interval and the counter runs to zero, plays a sound and flashes the display. Handy for cooking, workouts and short tasks where watching the clock is the last thing you want to do. A timer can be named, and the name shows up in the notification.
Stopwatch
Counts up
01:23.456
Counts from zero with millisecond precision. The lap button records a split without stopping the run, so the list shows both the time of each lap and the total from the start. The fastest and the slowest lap are marked.
Pomodoro technique
Focus
25 / 5 · 4 cycles
Alternates 25 minutes of work with 5 minutes of rest and grants a long break after four pomodoros. Phases switch on their own with a sound and completed stretches are counted. All four numbers can be changed when your rhythm differs.
Interval (Tabata)
Workouts
20 / 10 × 8
Alternates work and rest by rounds — for interval training where looking at a screen is not an option and the phase-change signal matters more than the digits. Ready schemes: Tabata, HIIT and strength; custom seconds and round counts work too.
Sound and notifications
Signal
tone · volume
The signal is generated in the browser instead of being downloaded as a file, so it works offline as well. Three tones, adjustable volume and a full mute. A browser notification is a separate switch and arrives even from a minimised tab once you allow it.
Runs in the background
Accuracy
system clock
The countdown does not tick in place: the tool remembers when the phase ends and compares against the system clock on every frame. A minimised tab, a sleeping laptop or an app switch cannot make it drift — and Pomodoro catches up on the phases it missed.

Frequently asked questions
Tap one of the ready presets — 1, 3, 5, 10, 15 or 25 minutes — or type hours, minutes and seconds by hand and press «Start». Kitchen presets are there too: tea and soft, medium or hard boiled eggs. A timer can be given a name, which then appears in the notification. When the time is up a sound plays and the display flashes.
Yes. The countdown is not a ticking counter: the tool stores the moment the timer ends and each frame shows the difference against the system clock. A minimised tab, a sleeping laptop or switching apps therefore cannot make it drift — when you come back the display shows the correct time rather than one that fell behind.
The direction of counting. A timer runs from a set value down to zero and signals at the end, which is what you want when the duration is known in advance. A stopwatch counts up from zero with millisecond precision and records laps, so you learn afterwards how long something took. The lap button marks a split without stopping the count.
It alternates focus and rest: 25 minutes of work, then a 5 minute break, and after every four such stretches a longer 15 minute break. All four numbers can be changed. The tool switches phases on its own with a sound, counts completed pomodoros and keeps the task you are working on in front of you.
Yes. One of three tones plays at the end; the volume can be adjusted and the sound switched off entirely. The tone is generated in the browser rather than downloaded as an audio file, so it works offline as well. A browser notification can be enabled separately and arrives even when the tab is minimised and sound is off.
No. Everything runs inside your browser: the time is measured on your device, the sound is generated there, and the timer name or pomodoro task never leave the page. Only the mode and the duration go into the page address, so that a link like «a 25 minute timer» can be shared. No text and no history of runs.
