Multi Timer & Stopwatch
Run several countdown timers and a lap stopwatch together on one page.
What this tool does
A multi timer runs several countdown timers at once, and this one pairs them with a lap stopwatch on the same page. Each timer keeps its own state, so pausing or resetting one leaves the others running - which is what makes it useful for cooking several dishes, running a classroom, or timing parallel lab steps. A single timer forces you to choose what to watch; this shows every countdown and its remaining time together.
Runs several independent countdown timers and a lap stopwatch together on one page.
Each timer holds its own state, so pausing or resetting one leaves the others running.
Laps record alongside running totals, so splits and cumulative times read together.
Names and times persist in the browser, so a reset session comes back configured.
How to use it
- Set a duration on any timer and press start - each runs independently.
- Add more timers with the add button, or remove the ones you do not need.
- Name each timer so a glance tells you which is which.
- Use the stopwatch alongside, recording laps as you go.
- Reset any single timer without touching the others.
Why use this tool
A multi timer runs several independent countdown timers and a lap stopwatch together on one page, and that togetherness is the whole point. Any single countdown forces a choice about which task to watch; a page of timers shows every remaining time at once, so nothing finishes unattended. The stopwatch rides along for the tasks measured from zero rather than to zero - laps for a circuit, splits for a run - without needing a second app.
Why we built it
We built this multi timer because the alternatives all break somewhere: phone timers stack behind each other in the notification shade, kitchen timers are one-per-device, and browser stopwatch tabs hide the instant you switch away. Keeping each timer's state independent - pause one, the others carry on - is the detail that turns a novelty into something you can cook a three-course meal with. The countdown timer covers the single-timer case and the pomodoro timer the work-break rhythm; this covers everything running in parallel.
For workouts that switch on fixed intervals rather than independent durations, the interval training timer runs the rounds for you, and the online stopwatch is the plain single-lap version.
Who this tool is for
- Cooking several dishes that must all land at the same time
- Teachers and presenters timing sections of a session
- Lab work with parallel steps running to different durations
- Anyone juggling tasks that each need their own countdown
When to use it
- Cooking a meal where each component has its own timing.
- Running a workshop with timed sections and a stopwatch for exercises.
- Monitoring several tests or processes with different timeouts.
- Comparing split times across a set without losing the total.
How it works
Each timer counts down from its own duration using the system clock, so pausing one never touches another's remaining time. The stopwatch counts up from zero and records laps with running totals - each lap shows its split and the cumulative time together. Times display in hours, minutes and seconds, and every timer that is running keeps counting if you scroll or switch tabs, because the page reads the clock rather than tallying ticks.
Browser tabs can throttle background timers, so a tab left hidden for a long time may fire its end signal late. Keep the tab visible, or pin it, when an accurate finish alert matters.
A worked example
These are the values the tool opens with, so you can see exactly how a session is set up. Change any timer on the page and it updates independently; the figures below describe the default arrangement.
| Timer | Duration | Purpose |
|---|---|---|
| Timer 1 | 10:00 | Pasta water |
| Timer 2 | 4:30 | Eggs |
| Timer 3 | 25:00 | Oven roast |
| Stopwatch | Counts up | Laps for plating |
With that setup, the tool shows:
- Three independent countdowns, each pausing on its own
- A stopwatch recording laps with running totals
- Named timers so each remaining time reads at a glance
- A reset that touches one timer only
What you enter, and what you get back
| Item | Details |
|---|---|
| Durations | Hours, minutes and seconds per timer. |
| Names | A short label for each timer. |
| Result | Independent countdowns, a lap stopwatch, and audio signal at zero. |
Issues you may run into
| What you see | Why it happens | What to do |
|---|---|---|
| No sound at zero | Tab muted or audio blocked. | Allow audio for the page and keep the tab visible. |
| Timer finished while away | Background tab throttled. | Pin the tab when timing matters. |
| Lost setup on reload | Browser data cleared. | Timers persist locally; clearing site data resets them. |
| Times look crowded | Too many timers at once. | Remove unused timers - each is independent. |
Assumptions and limitations
- Browser tabs may throttle timers running in the background, delaying the end signal.
- Audio alerts depend on the browser allowing sound for the page.
- Timer settings persist in the browser only; clearing site data resets them.
- Not a scheduling tool - timers run from the moment you start them, not from a set clock time.
Frequently asked questions
Can I run multiple timers at once?
Yes - each timer on this page runs independently, with its own duration and state. Starting, pausing or resetting one never affects the others, so every countdown keeps its own remaining time.
Does the stopwatch support laps?
Yes. The stopwatch records laps alongside running totals, so each lap shows both its split time and the cumulative time since the start - the two numbers you actually need when working through a set.
Can I pause one timer without stopping the others?
Yes. Pause and reset act only on the timer you press them on. The remaining timers carry on counting untouched, which is the core difference from stacking phone timers in a notification shade.
Can I name each timer?
Yes. Every timer takes a short label - 'pasta', 'eggs', 'roast' - so you can tell the countdowns apart at a glance. Names are stored in the browser along with the durations.
Do the timers keep running if I switch tabs?
The countdowns are based on the system clock, so they keep the correct remaining time even while the tab is hidden. However, a background tab may throttle the end-of-timer alert, so keep the tab visible when the finish signal matters.
Is the multi timer free to use?
Yes, completely free, with no account and nothing uploaded. Everything runs in the browser, and your timer names and durations are stored locally on your device only.
