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 sounds including Soft Bells, Arpeggio, Good Morning, Solemn Bell and Rooster, and adjust the volume. Vibration is requested only on supported devices with the option enabled.

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

The timer automatically requests Screen Wake Lock while a countdown runs. The request can be rejected or released depending on browser support, power-saving settings and tab visibility. It is released when the timer stops or you leave the page, and cannot prevent device sleep or browser termination.

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 — Choose a sound and volume, then use the preview to check it. A vibration option is available on supported devices. Browser notifications depend on support and notification permission.
  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 TimerSet 1 second to 23 hours, 59 minutes, 59 secondsCooking 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 flexible but counts down only one duration at a time. Pomodoro's 25/5 cycle is a starting setting you can adjust around meetings and interruptions; it is not a proven optimal ratio. Intervals suit short exercise or practice rounds but need round setup. The multi-timer runs several countdowns at once with a busier screen. Open the dedicated page in the table for the mode that fits your task.

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

Preview the sound first and check the timer volume, device media volume, tab mute setting and audio output device. Clicking Start or pressing Space does not guarantee that the completion sound will play; browser playback policies and device state can still prevent it. While the page runs, the alarm is set to repeat every 4 seconds and stop after 30 seconds. Vibration is requested only on supported devices with the option enabled.

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 shows completed-session counts for today, this week, and the last 90 days, plus the sum of configured focus minutes.

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?

The end time is saved in this browser, so returning to the timer page restores its remaining time. Alarm sounds and notifications need this timer page to stay open and the browser to run it. Open other tools in a separate tab if you need this timer’s alert. Changing your device’s clock can change the remaining countdown.

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?

Completion is checked while the browser keeps the page running. Remaining time is calculated from the saved end time and your device clock, but background-tab limits, screen lock or sleep can delay or suppress the alert. The delay is not limited to a few seconds, and changing your device clock can change the remaining time. No alert is sent while the tab is closed.

Will a refresh reset my timer?

If browser storage is available and the saved data remains, reopening in the same device and browser restores the remaining time from the end time. If that time has passed, the timer restores at zero without replaying the missed completion sound. Blocking storage or deleting the data prevents restoration, and the timer does not carry over to another device or 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.
