Every timer you need, in one place — kitchen, workouts, focus, games and more

Multiple timers at once

A single countdown is fine until you are cooking a real meal, at which point one timer becomes actively unhelpful. The Multi-timers tab lets you run as many independent countdowns as you need, side by side, each with its own name, duration and alarm sound. Every card shows its own progress bar, and each can be paused, resumed or removed without touching the others.

A worked example: getting dinner on the table

Say you are making roast chicken with potatoes and green beans. Chicken goes in first — name a timer "Chicken", set 60 minutes, give it the classic bell. Twenty-five minutes later, potatoes: another timer, 35 minutes, digital alarm. Ten minutes before the end, the beans: 10 minutes, chime. Three timers, three distinct sounds, and you can tell from the next room which one just went off without looking.

The distinct-sound trick is the whole point. With one shared alarm you still have to walk over and read the screen. With different sounds per timer, you learn them in a single evening.

Adding, pausing and clearing timers

Give the timer a name, set minutes and seconds, choose a sound, and press Add. Each card carries Start, Pause and Stop, plus an ✕ in the corner to remove it. Quick-add buttons above the grid cover the most common kitchen durations — eggs, pasta, cake, pizza, popcorn, potatoes, chicken — so a full set of timers takes seconds to build.

Beyond the kitchen

The same pattern works anywhere several things run in parallel. Laundry and dishwasher cycles. Two children on shared screen time. A parking meter and a load of laundry. Batch tasks at work where each has a different deadline. Anything you would otherwise track by glancing at a clock and doing arithmetic.

Your timers survive a reload

If you have allowed local saving, running timers are stored on your device and restored when you come back — with the remaining time recalculated from the real clock, not from where the page left off. Close the tab by accident mid-roast and the chicken timer is still correct when you reopen it.

Interval sequences: Tabata, HIIT, CrossFit, Yoga, Pomodoro

Some routines are not one duration but a chain of them, and re-setting a timer between every phase defeats the purpose. The Sequences tab lets you build a list of named steps that run back to back automatically, announcing each transition so you never have to look at the screen mid-burpee.

Ready-made workout presets

Tabata is the strictest and shortest: 20 seconds all-out, 10 seconds rest, eight rounds, four minutes total. It comes from Japanese research on speed skaters and it is genuinely brutal if you do it properly. HIIT is the looser family it belongs to — longer work intervals, longer recovery, more forgiving. CrossFit loads a circuit structure with warm-up, work blocks and rest. Yoga takes the opposite approach: long holds, gentle transitions, a calm end sound instead of a klaxon. Advanced Pomodoro builds a full work session — focus blocks, short breaks, and a longer break after the fourth cycle.

Building your own sequence

Add steps one at a time with a name and a duration. Reorder with the ▲▼ arrows, duplicate with ⧉, delete with ✕. Duplication is the feature that saves the most time in practice: build "Exercise 40s" and "Rest 20s" once, then duplicate the pair as many times as your circuit needs, renaming as you go.

A beep sounds during the last three seconds of every phase so you can anticipate the change, and a voice announces each transition by name using your browser's speech synthesis. You keep your eyes on the exercise instead of the screen. Voice can be switched off, and the step-change sound is chosen from the same ten alarms as everywhere else.

Saving programs you will reuse

Once a sequence works, name it and save it. It stays on your device and reloads with one click, so your Monday session, your warm-up routine and your study pattern are always a tap away. Saving requires local storage to be enabled.

Online stopwatch with laps

A countdown answers "how long until"; a stopwatch answers "how long did that take". The Best Timers stopwatch counts up with hundredth-of-a-second precision and keeps running accurately in a background tab, because it too is calculated against a reference clock rather than incremented by a ticker. Leave it running while you switch to another tab and the elapsed time will still be exact when you come back.

Lap times and splits

Press Lap to record a split without stopping the clock. Each lap shows both its individual duration and the cumulative total, which is exactly what you need for running intervals, swimming sets, or timing how long each stage of a process actually takes. The fastest and slowest laps are highlighted in the list, so patterns jump out without exporting anything to a spreadsheet.

That distinction between lap time and total time trips people up on physical stopwatches all the time. Here both numbers sit side by side on every row, so there is nothing to work out in your head mid-session.

Start, pause, reset

Start begins timing, Pause freezes the display without losing the elapsed total, and Reset clears everything including the lap list. Fullscreen enlarges the digits enough to read from the far side of a gym, a pool deck or a classroom — useful when the person timing is not the person being timed.

What people use it for

Track intervals on the treadmill or in the pool. Time a presentation rehearsal so you know whether you are running long. Measure how long a recurring task really takes before you commit to an estimate. Time a science experiment or a cooking step where the duration matters but you do not know it in advance. Referee a school sports day. Any situation where you would otherwise squint at a wall clock and do subtraction.

Why a browser stopwatch beats the one on your phone

Your phone has a stopwatch, but it is behind a lock screen and an app, and it disappears the moment a call comes in. A browser tab stays open on a second monitor all afternoon, shows far bigger digits, keeps a visible lap history you can read at a glance, and is one bookmark away on every machine you use. There is nothing to install and nothing to update.

Alarm history

Every alarm that fires — from the main timer, a multi-timer or a sequence step — is logged with its date and time in the History tab. Nothing is added manually; the log builds itself as you work.

What it is actually good for

Reconstructing what happened. How many Pomodoro cycles you really completed, as opposed to how many you remember. How many sets you got through. What time each dish went in the oven. When each market signal fired. And, occasionally, confirming that an alarm really did go off and you slept through it.

It is also the quickest way to answer "how long have I been at this?" after a long session, since the first and last entries bracket the whole thing without you having to have started a separate timer.

A simple record of your day

Because every tool on the site writes to the same log, the history doubles as a rough timeline: cooking, focus blocks, workouts and games all appear in one chronological list. For anyone tracking how their time actually gets spent, that is more honest than a plan written in the morning. A Clear button empties the log whenever you want a fresh start.

Kept privately, on your device

With local saving enabled, history persists between visits so you can look at patterns over several days. All of it stays on your device. None of it is sent anywhere, and you can clear the log or switch saving off entirely at any time from the link in the footer.

Free online metronome

Tempo is the backbone of a piece of music. Whether you are working through your first scales, preparing for a recital, or just trying to stop rushing the chorus, a reliable metronome changes how fast you improve — and here it is always one tab away, with nothing to install. Set the tempo anywhere from 30 to 260 beats per minute, choose how many beats are in a measure, and press start: every beat gets a click and a visual marker, with a stronger accent on beat one.

A genuinely steady pulse

A metronome is only worth using if it is rock solid — the smallest wobble and your ear catches it immediately. This one does not simply fire a sound on an interval. Each click is scheduled in advance on the browser's audio clock, the same timing layer used for music production. The result holds steady at 240 BPM and stays that way through a long practice session. You can trust the click with your eyes shut.

Finding a tempo you do not know

Have a song in your head but no idea of its tempo? Tap the beat on the Tap tempo button and the metronome works out the BPM from your taps. It is the quickest way to lift the tempo of a recording, get a band starting together, or recover the speed of something you learned by ear. The traditional tempo marking is displayed as you go — Largo, Adagio, Andante, Moderato, Allegro, Presto — and preset buttons cover the most common values.

Time signatures and downbeats

Choose 3 beats per measure and you get the lilt of a waltz; 4 gives you the standard measure behind most pop, rock and country; 6/8 gives a compound feel that breathes differently. The first beat of each measure is emphasized both in sound and on screen, which helps enormously with feeling the shape of a piece and not losing your place — particularly in a syncopated passage or a bar you keep fumbling.

How to actually practice with one

The trick is not to play fast, it is to play accurately. Start a passage well below your limit, at a tempo where every note lands exactly on the click, and only move up a few BPM once it is clean and even. That patient climb — a handful of beats at a time — is by far the most reliable way to build speed without sacrificing precision, whether you play piano, guitar, drums, strings or sing.

Sleep cycle calculator: waking up at the right moment

You know the feeling: two mornings, the same number of hours in bed, and completely different results — clear-headed one day, wrecked the next. The difference often has less to do with how much you slept than with exactly when the alarm went off. Sleep runs in cycles of roughly 90 minutes, and being pulled out of deep sleep partway through one is a reliable recipe for a bad morning.

This calculator works from that idea: aim for a wake-up that lands at the end of a cycle, when sleep is lightest. Tell it what time you are going to bed and it suggests the best times to wake. Or work backwards: give it the time you have to be up, and it tells you when to turn in.

"If I go to bed at 11 pm, when should I wake up?"

This is the question the tool exists to answer. For an 11 pm bedtime, allowing about fifteen minutes to fall asleep, the cycle-aligned wake times land at 6:45 am (5 cycles, 7.5 hours) or 8:15 am (6 cycles, 9 hours). Rather than setting your alarm to a round number out of habit, you pick a time that respects the shape of your night — and one button turns that slot into an actual alarm in the timer.

How the calculation works

Starting from your bedtime, the tool adds the average time it takes to fall asleep — about 15 minutes — then stacks 90-minute cycles to offer wake-ups after 3, 4, 5 or 6 cycles. In wake-up mode it runs the same math in reverse from the time you need to be up. The 5- and 6-cycle options — roughly 7.5 to 9 hours — are highlighted, since that is the range recommended for most adults.

How many cycles should you aim for?

Five or six suits most adults. Three or four is not a substitute for a full night, but it can rescue a short one: waking rested after four complete cycles beats being dragged out of the middle of a fifth. That is precisely the situation where planning around cycles pays off — the night you already know is going to be short.

A useful guide, not an exact science

Worth being straight about: 90 minutes is an average. Real cycle length varies between people and across the night — the cycles near morning are not the same as the ones at the start. Sleep need also shifts with age, activity and accumulated tiredness. Treat these times as a practical starting point and adjust to what actually leaves you feeling rested. If your sleep is a persistent worry, that is a conversation for a doctor rather than a calculator.
