How many timers can I run at once?

Up to 6 simultaneous timers. Each runs independently so they don't interfere with each other.

What happens when a countdown finishes?

A chime sound plays through the Web Audio API and a browser notification is dispatched. The timer card flashes to draw attention.

Can I mix countdown and stopwatch timers?

Yes. Each timer has its own mode selected independently, so you can have some counting down and others running as stopwatches simultaneously.

Does it work if I switch browser tabs?

Yes. Timers continue running in the background. The browser notification ensures you are alerted even when the tab is not active.

About this tool

Unlike a single stopwatch or Pomodoro, this tool lets you run up to 6 fully independent timers at once — each with its own name, colour, and mode. Countdown timers show a ring-style progress indicator and fire a browser notification plus audio alert at zero. Stopwatch timers support start, stop, reset, and lap recording.

How to use

1 Step 1: Click 'Add Timer' to create a new timer. Give it a name and choose Countdown or Stopwatch mode.
2 Step 2: For Countdown mode, set the target time in HH:MM:SS format and press Start to begin the countdown.
3 Step 3: For Stopwatch mode, use Start/Stop to control timing and Lap to record split times.
4 Step 4: When a countdown reaches zero, an audio chime plays and a browser notification is sent (allow notifications when prompted).
