Multiple stopwatches
Run Multiple Stopwatches at Once
Perfect for coaching drills, cooking, lab experiments, or tracking several tasks at the same time. Up to 20 independent timers.
Why run multiple stopwatches at once?
A single stopwatch is fine when you're timing one thing. But real life rarely works that way. A coach running drills with three athletes at once needs three splits, not one. A cook watching two dishes plus a resting steak needs three clocks. A chemistry TA monitoring parallel reactions needs one per beaker.
TimerHubs lets you spin up to 20 independent stopwatches on the same page. Name each one so you don't lose track — "Left burner," "Runner 3," "Reaction A." Start, pause, and reset each individually, or use the bulk controls to start or reset every timer in one click.
Everything runs in your browser. Nothing uploads, nothing installs, nothing signs you up. Refresh the page and your timers persist. Prefer a single-focus stopwatch instead? Use the standard stopwatch, or grab a countdown timer or Pomodoro session from the toolbox.
Common uses
- • Coaching & PE: time multiple athletes on the same drill.
- • Cooking: one timer per dish, plus a separate one for resting meat.
- • Science labs: track parallel experiments with named beakers.
- • Board games & chess variants: per-player time budgets.
- • Work & consulting: track time on multiple tasks or clients at once.
- • Fitness circuits: track rest periods for different stations.
Frequently Asked Questions
How many stopwatches can I run at once?+
Up to 20 independent stopwatches on the same page. Each runs on its own clock and can be started, paused, and reset without affecting the others.
Do the stopwatches keep running if I switch tabs?+
Yes. Timers use Date.now() snapshots so they stay accurate even when the browser throttles background tabs.
Will I lose my timers if I refresh?+
No. Each stopwatch's name and elapsed time is saved to your browser. Running timers are frozen on refresh so nothing keeps counting in the background — hit Start to resume.
Can I name each stopwatch?+
Yes — just click the label at the top of any timer and type a new name. Great for keeping track of which timer is for which task, athlete, or dish.
