What is an Online Timer?

An online timer is a free countdown timer you can use directly in your web browser. Set hours, minutes, and seconds freely, and get an alarm when the countdown ends. Use it as a cooking timer, study timer, workout timer, and more.

It offers 4 modes (Timer, Pomodoro, Interval, Multi Timer), 15 alarm sounds, vibration alerts, screen wake lock, and keyboard shortcuts. No installation required - use it on PC and mobile instantly.

Key Features

4 Modes

Timer, Pomodoro, Interval, and Multi Timer each live on their own dedicated page, and each keeps its own progress independently.

15 Alarm Sounds & Vibration

Choose from 15 alarm sounds including Soft Bells, Arpeggio, Good Morning, Solemn Bell, and Rooster. Volume control and vibration also supported.

Keyboard Shortcuts

Start or pause with the spacebar and reset with R — control the timer without leaving your keyboard.

Presets & URL Sharing

Set common durations fast with the +1min/+5min preset buttons and the dedicated 1/3/5 minute pages, then share the time you set via URL.

Screen Wake Lock

While the countdown runs, the browser Screen Wake Lock keeps the display from switching off. It is released as soon as you stop the timer or leave the page, and browsers without Wake Lock support simply skip it.

How to Use

  1. Step 1: Choose Mode — Timer, Pomodoro, Interval, and Multi Timer each have their own URL. This page is the basic timer; open the others from the top menu or the related tools links below.
  2. Step 2: Set Time — Enter hours/minutes/seconds or use preset buttons for quick setup.
  3. Step 3: Alarm & Options — Configure alarm sound, volume, and vibration.
  4. Step 4: Start — Click Start or press the Space bar to begin the countdown. While it runs, Space pauses and R resets.

Timer 4-Mode Comparison Matrix

Clock-Tani's timer hub bundles four modes — simple timer, Pomodoro, interval (Tabata), and multi-timer — into one page. When you are unsure which one fits your situation, this matrix lets you compare recommended durations, ideal use cases, and dedicated pages at a glance so you can pick the right tool in seconds.

ModeRecommended DurationBest ForDedicated Page
Simple TimerFree, 1 sec to 5 hoursCooking ramen or eggs, laundry alerts, brushing or shower timing/en/timer
Pomodoro25 min focus / 5 min break (15 min long break every 4 cycles)Studying, coding, writing, and other deep-work sessions/en/pomodoro
Interval (Tabata)20 sec work / 10 sec rest x 8 rounds (4 min total) or 40/20HIIT like burpees and jump squats, flashcard drills, speed practice/en/interval
Multi-TimerN timers running in parallelCooking stew + rice + side dishes, juggling laundry/cleaning/dinner, board-game turns/en/multi-timer

The simple timer is the most flexible but only counts one thing at a time. Pomodoro's 25/5 cycle is a proven focus protocol, yet it breaks down for meeting-heavy days. Intervals shine for short, intense bouts of exercise or memorisation but need round setup, while the multi-timer handles parallel tasks at the cost of a busier screen. Jump straight to the dedicated page in the table to launch the mode that fits your moment.

Use Cases

Cooking & Kitchen

Set precise cooking times for noodles (3 min), pasta (8 min), oven recipes, and more.

Study & Learning

Set focus time for efficient studying. Even more effective when combined with Pomodoro mode.

Exercise & Training

Use Interval mode for Tabata, HIIT, and various workout programs.

Work & Meetings

Manage presentation time, meeting duration, and boost work efficiency.

Frequently Asked Questions (FAQ)

The timer finished but no alarm played

Browsers block audio until you have interacted with the page. If you started the countdown with the Start button or the Space key, that interaction counts as permission and the alarm will play. If you still hear nothing, check your device's media volume and whether the tab is muted. The alarm repeats every 4 seconds and stops on its own after 30 seconds; on phones that support vibration, it buzzes alongside the sound.

How long should I set for instant noodles?

Packet and cup noodles usually need 3 minutes; thicker sauce-style noodles need 4 to 5. Spin the minutes wheel to 3, or tap the +1m button three times, then press Start. Your last entered time is remembered, so the same setting is waiting for you the next time you open the page in this browser.

Timer, Pomodoro, Interval or Multi — which one should I use?

If you are timing one thing and you are done when it rings, the plain timer on this page is the right pick. If you need to alternate focus and rest, use Pomodoro (25 minutes of focus and 5 of break by default, with a long break every fourth session). If you need short rounds measured in seconds, use Interval (20 seconds of work and 10 of rest across 8 rounds by default). If you need several different durations running side by side, use the Multi timer. The Pomodoro page additionally keeps a count of completed sessions and focus minutes for today, this week and all time.

Why does each mode have its own address?

The four modes have different settings and different screens, so they live at /en/timer, /en/pomodoro, /en/interval and /en/multi-timer. Their countdowns are stored separately too, so leaving a plain timer running while you switch to the Pomodoro page does not overwrite either one. Round progress only appears on the interval page, and the list of timer cards only on the multi-timer page.

Does the countdown stop if I move to another page?

Not while you stay on this site. Remaining time is derived from the moment the timer is due to end minus the current clock, rather than counted down second by second, so you can visit the Pomodoro or Multi timer page and come back without losing a second. If you leave the site entirely, no alarm sounds while you are away and the timer simply shows as finished when you return.

What is the longest time I can set?

Up to 23 hours 59 minutes 59 seconds using the hour, minute and second wheels. The +1s, +5s, +1m, +5m, +1h and +5h buttons add to whatever is already entered, so tapping +5h twice gives you 10 hours. Those buttons appear only on the setup screen — a running countdown cannot be extended, so press Reset (or the R key) and enter the new time.

How do I run several timers at once?

This page counts one thing at a time. When you need different durations running together — rice, stew and something in the oven — use the Multi timer page. It holds up to 10 timers on one screen, each with its own name and colour so you can tell which one just rang, and a set you use often can be saved as a template and reloaded in one click.

Does the timer keep running in a background tab?

Yes, as long as the tab stays open. Remaining time is calculated as the end moment minus the current clock, so the browser throttling background tabs does not make it drift. The alarm may sound a few seconds late while the tab is hidden, and closing the tab means no alert at all. On phones the browser may suspend the page once the screen turns off, so leave the screen on for a timer you cannot afford to miss.

Will a refresh reset my timer?

No. The end moment of a running timer is stored in your browser, so refreshing — or closing the tab and reopening it in the same browser — brings the remaining time back. If that moment already passed while you were away, the timer shows as finished. Because the value lives in this browser only, it does not follow you to another device or another browser.

Timer vs Stopwatch: When to Use Which?

A timer counts down from a set duration to zero and alerts you when time is up. A stopwatch counts up from zero to measure elapsed time. Though similar, they serve fundamentally different purposes.

Use a timer when: You know the duration in advance — cooking pasta for 8 minutes, a 25-minute Pomodoro focus session, a 60-second plank hold, or a 15-minute meeting break. Timers are about discipline and deadlines.

Use a stopwatch when: You want to measure how long something takes — timing a 5K run, tracking how long you study, measuring a presentation rehearsal, or recording lap times. Stopwatches are about measurement and analysis.

Some tasks benefit from both: time your first attempt with a stopwatch to establish a baseline, then use that measurement as a timer target for future attempts.

Cooking Time Reference Chart

Accurate timing is essential in cooking. Here are common reference times for popular ingredients:

Boiling: Soft-boiled egg: 6-7 min | Hard-boiled egg: 10-12 min | Pasta (al dente): 8-10 min | Rice: 15-18 min | Potatoes (cubed): 15-20 min

Baking (350°F / 180°C): Cookies: 10-12 min | Brownies: 25-30 min | Chicken breast: 25-30 min | Whole chicken: 60-90 min | Pizza: 12-15 min

Grilling: Burger patty (medium): 4-5 min per side | Steak (medium-rare, 1-inch): 3-4 min per side | Salmon fillet: 4-5 min per side | Vegetables: 5-10 min total

Steeping tea: Green tea: 2-3 min at 175°F | Black tea: 3-5 min at 212°F | Herbal tea: 5-7 min at 212°F | Oolong: 3-5 min at 195°F

These are guidelines — always adjust for your specific equipment and preferences.
