Online Timer
Free countdown timer with alarm clock — no download, no signup.
Online timer
An online timer is a free countdown timer that runs entirely in your web browser — no app to install, no account to create, no download. You set a duration in hours, minutes and seconds, press start, and the page counts down to zero and plays an alarm sound. It works on any device with a browser: laptop, desktop, tablet or phone.
People reach for an online timer dozens of times a day: timing a 5-minute tea steep, a 25-minute Pomodoro focus block, a 20-minute power nap, a 10-minute classroom activity, or the rest between workout sets. Because it lives on a web page, it is always one bookmark away — which matters now that the old Google Search timer widget has become unreliable and sometimes disappears from results.
Countdown timer
A countdown timer counts down from a duration you choose to zero, then signals with an alarm. That is the whole difference between it and a stopwatch: a stopwatch counts up from zero to measure how long something took, while a countdown timer tells you when your allotted time is over.
Countdown timers are the right tool whenever there is a deadline: the pasta must come off at 9 minutes, the exam section ends in 20 minutes, the meeting must wrap in 30. The progress ring above shows elapsed time at a glance, and the browser tab title shows the live countdown (for example 00:04:59 – jobi99 Online Timer), so you can watch another tab and still see the time ticking.
Common countdown durations people search for
| Duration | Popular for |
|---|---|
| 1 minute timer | Planks, short rests, microwave bursts |
| 5 minute timer | Tea, short breaks, classroom transitions |
| 10 minute timer | Meditation starters, quick study sprints |
| 15 minute timer | Cleaning bursts, Pomodoro short breaks |
| 20 minute timer | Power naps, HIIT sessions |
| 25 minute timer | Pomodoro focus blocks |
| 30 minute timer | Meetings, cooking, presentations |
| 45 minute timer | Class periods, deep-work blocks |
| 1 hour timer | Exams, workouts, baking |
Every one of these is a single tap on the preset chips above the tool — no typing needed.
Free online timer with alarm clock
This is a 100% free online timer with an alarm clock built in. Set any duration and when the countdown reaches zero you get a proper alarm: a synthesized alarm sound played through your device speakers (no audio files to load), a flashing “Time’s up!” state, and vibration on phones that support it.
Alarm sounds included
- Triple beep — the classic digital timer sound, three short 880 Hz beeps.
- Five beeps — a longer, harder-to-miss alert for noisy rooms.
- Soft chime — two gentle tones for meditation, classrooms and shared offices.
Press Test sound before you start an important timer so you know exactly what you will hear, and use the volume slider to match your room. One honest note: browsers block all sound until you interact with the page (a click or keypress), which is why the Start button unlocks the audio — and why the test button exists.

About TickCounter Timer
TickCounter (tickcounter.com) is one of the best-known names in online timers. Based on their public description, their “Online Timer With Alarm Clock” page works like this: set the timer to a chosen number of hours, minutes and seconds, confirm with a Set Timer button, press Start to begin counting, press Stop to pause, and Reset to start over. They position it as a free way to “wake up on time, manage your day and track tasks,” with support for multiple alarms and a variety of alarm sounds.
TickCounter’s main business, though, is shareable event countdown widgets — days, hours, minutes and seconds until a date, designed to be shared with friends or embedded in a website. Their duration timer is a simpler companion page.
How this jobi99 timer compares: everything TickCounter’s timer page offers (hours/minutes/seconds input, start, pause, reset, free, no signup) is here, plus a few things their page does not emphasize — one-tap preset chips including a 25-minute Pomodoro, a live progress ring, the countdown shown in the browser tab title, fullscreen mode for classrooms, a repeat/loop switch, and timestamp-based timing that stays accurate when the tab is in the background.
How do I use an online timer?
- Set the duration. Type hours, minutes and seconds into the three boxes, or tap a preset chip (1 min … 1 hour, including a 25-minute Pomodoro chip).
- Pick your alarm. Choose triple beep, five beeps or soft chime from the dropdown, set the volume, and press Test sound to hear it.
- Press Start. The ring starts filling, the display counts down, and your browser tab title shows the live time. The tool also tells you the clock time your timer ends at.
- Pause or reset anytime. Pause freezes the countdown exactly where it is; Resume continues from the same second. Reset clears everything back to your inputs.
- Go fullscreen for groups. The Fullscreen button expands the timer for classrooms, meetings and presentations.
- Loop it. Tick Repeat and the same duration restarts automatically after each alarm — handy for interval training and classroom rotations.
Keyboard shortcuts: Space starts or pauses, R resets (when you are not typing in a box).
Pomodoro Timer Online (25-Minute Focus Timer)
The Pomodoro Technique, created by Francesco Cirillo in the late 1980s, is the most famous productivity use of a countdown timer. The classic cycle is simple:
- Set 25 minutes, work with full focus until the alarm.
- Take a 5-minute short break.
- Repeat four times, then take a 15–20 minute long break.
Popular variations use the same idea with different ratios: 50/10 for deep technical work and 90/15 for long creative sessions. Use the 25 min Pomodoro chip above for focus blocks and the 5 min chip for breaks; tick Repeat if you want the rhythm to keep cycling while you track sessions on paper. Short, timed sprints with real breaks beat open-ended “work until tired” for most people — the timer removes the decision of when to stop.
Interval & Tabata Timer for Workouts
Countdown timers are the backbone of interval training. The most famous protocol is Tabata, developed by Dr. Izumi Tabata: 20 seconds of all-out work followed by 10 seconds of rest, repeated for 8 rounds — exactly 4 minutes, a 2:1 work-to-rest ratio.
| Protocol | Work | Rest | Rounds |
|---|---|---|---|
| Tabata | 20 sec | 10 sec | 8 (4 minutes total) |
| Classic HIIT | 30 sec | 30 sec | 8–12 (1:1 ratio) |
| EMOM | 40 sec | 20 sec | Every minute on the minute |
| Beginner intervals | 30 sec | 60 sec | 6–8 (1:2 ratio) |
| Strength rest timer | — | 90 sec–3 min | Between sets |
How to run intervals here: set the work duration, tick Repeat, and press Start — the alarm marks every round while you alternate work and rest. For strict Tabata timing, alternate the 20-second and 10-second presets between rounds.
Online Timer Uses: Kitchen, Classroom, Exams, Meetings, Meditation
| Use case | Suggested duration | Tip |
|---|---|---|
| Boiling eggs | 6–12 min | 6 soft, 9 jammy, 12 hard |
| Pasta & rice | 8–12 min | Start when the water returns to a boil |
| Baking | Per recipe | Set it the moment the tray goes in |
| Power nap | 20 min | Short enough to avoid grogginess |
| Meditation | 10–20 min | Use the soft chime alarm |
| Classroom activity | 5–15 min | Fullscreen mode so the whole room sees it |
| Exam sections | Per section | The tab-title countdown keeps you honest |
| Meetings | 25 or 50 min | End 5 minutes before the hour |
| Presentations | Per slot | Glance at the progress ring, not your phone |
| Workout rest | 30–90 sec | Tick Repeat between sets |
| Study sprints | 25 min | Pair with the Pomodoro method above |
Countdown Timer vs Stopwatch — What’s the Difference?
| Countdown timer | Stopwatch | |
|---|---|---|
| Direction | Counts down to zero | Counts up from zero |
| Start | You set the duration first | You just press start |
| Finish | Alarm sounds at zero | You press stop; it shows elapsed time |
| Extra features | Presets, repeat, alarm sounds | Lap / split times |
| Best for | Deadlines, cooking, Pomodoro, intervals | Racing, timing how long something took |
Rule of thumb: if you need to be stopped at a time, use a countdown timer; if you need to measure a time, use a stopwatch. This page is the countdown timer — for elapsed-time measurement with laps, a stopwatch tool is the right pick.
Why Your Online Timer Alarm Sometimes Fails (Browser Limits)
Online timers are honest tools, and honesty includes their limits. Here is why an alarm occasionally misbehaves — on any timer site, not just this one — and how to prevent it:
- Sound needs a click first. Every major browser blocks audio until you interact with the page (this is the autoplay policy). If you loaded a timer and never clicked anything, the alarm cannot play. Pressing Start counts as the interaction — and the Test sound button proves it works.
- Background tabs get throttled. Chrome slows timers in hidden tabs to save battery. Cheap countdowns that subtract one second per tick drift or freeze; this timer computes remaining time from an absolute end timestamp on every tick, so the displayed time stays correct even when throttled.
- Closing the tab kills the timer. The countdown lives inside this page. Close the tab and it is gone — no timer site can sound an alarm from a closed tab.
- Sleep mode stops everything. If your laptop sleeps, all web timers pause. For anything critical, disable sleep or use your phone’s clock app.
- Phones lock audio. On iPhones especially, locking the screen can suspend web audio. Keep the page visible for important alarms.
Follow the three rules in the how-to section (tab open, device awake, volume up) and the alarm will sound every time.
