Online Timer

A free, browser-based timer for cooking, workouts, study sessions, meetings, and anything else that runs on the clock. No installs, no accounts — just open the page and start counting down.

What is a timer?

A timer counts down from a set duration to zero and alerts you when time is up. It's the mirror image of a stopwatch, which counts up from zero instead. This online timer runs entirely in your browser: pick or enter a duration, start it, and it keeps counting even if you switch to another tab.


How do I use the online timer?

  1. 1

    Choose a duration

    Tap a preset (5, 10, 20, 30, 45 minutes, or 1 hour), or tap the displayed time to enter your own hours, minutes, and seconds.

  2. 2

    Start it

    Press the play button, or hit Space, to begin the countdown.

  3. 3

    Adjust on the fly

    Add time with the +0:30 / +1:00 / +5:00 buttons, or pause and edit the remaining time directly.

  4. 4

    Get notified

    A chime plays when the timer reaches zero. Turn repeat on beforehand if you want it to restart automatically.


What are its key functionalities?

One-tap start

Pick a preset or set your own duration, then start counting down immediately — no sign-up, no install.

Editable duration

Tap the time to open the duration editor and dial in hours, minutes, and seconds at any point, even mid-run.

Repeat mode

Turn on repeat and the timer automatically restarts each time it reaches zero — ideal for intervals and rounds.

Full keyboard control

Start, pause, reset, adjust, and set durations without touching the mouse. See the shortcut list below.

Fullscreen mode

Expand the timer to fill the screen for visibility across a room — a classroom, kitchen, or presentation.

Sound on or off

A distinct chime plays when time is up. Mute it instantly if you're somewhere quiet.


Why use this timer?

It's fast, distraction-free, and doesn't ask anything of you. There's no account to create and no app to download — open the page on any device and it's ready. The interface stays out of the way: a clear countdown ring, a handful of presets, and controls that respond instantly, whether you tap them or use the keyboard.


What are the use cases of the timer?

Cooking

Track multiple dishes at once without guessing when the pasta's done.

Workouts

Time sets, rest periods, and interval rounds with repeat mode.

Studying

Run focused study blocks and structured breaks back to back.

Meetings

Keep agenda items and standups moving without watching the clock yourself.

Presentations

Put the timer in fullscreen so speakers can self-pace on stage.

Games & activities

Set turn limits for board games, quizzes, and classroom activities.


Are timers effective for productivity?

For most people, yes. Working against a visible countdown creates a sense of urgency that helps reduce procrastination, and it turns open-ended tasks into bounded ones you can commit to starting. Timed work-and-break patterns, like short focused sprints followed by a deliberate pause, are widely used for exactly this reason. A timer won't fix a task that's poorly planned, but it removes the friction of tracking time yourself so you can stay focused on the work itself.

FAQ

Does it work on mobile devices?

Yes. The timer is fully responsive and works in any modern mobile browser — no app to install. Tap targets, the duration editor, and fullscreen mode all adapt to touch screens.

Can I use keyboard shortcuts?

Yes. On a device with a physical keyboard you can start and pause with Space, adjust the duration with the arrow keys, reset with R, toggle repeat with Shift+R, jump straight to a duration by typing minutes on the number keys, open the duration editor with T, and enter or leave fullscreen with F.

Can you edit or set the desired time on the timer?

Yes. Tap the displayed time (or press T) to open the duration editor, where you can set hours, minutes, and seconds directly. You can also choose a preset, use the quick +0:30 / +1:00 / +5:00 buttons, or type a duration on the number keys.
