Will the timer make a sound when it hits zero?

Yes. When the countdown reaches 0:00 a short beep plays automatically. Make sure your device volume is turned up and your browser tab is not muted.

Does the timer keep running in the background?

Yes. The timer uses the system clock, so it stays accurate even if you switch tabs or minimise the window. However, if you close the tab the timer stops.

How accurate is the stopwatch?

The stopwatch measures elapsed time using performance.now() and is accurate to the millisecond. All timing runs client-side in your browser.

Is my data stored anywhere?

No. The timer and stopwatch run entirely in your browser. No data is sent to any server.

Technical Fairness & Accuracy

The countdown timer tracks time using the system clock (Date.now()) rather than interval ticks. This means the timer stays accurate even if your browser throttles background tabs. The stopwatch uses performance.now() for sub-millisecond precision. All calculations are done in your browser — nothing is sent to a server.

🔒 Privacy first. Your timer settings and lap history are never uploaded. Everything lives in your current browser tab only and resets when you close the page.

Frequently Asked Questions

How do I set a 5 minute timer?

Click the 5 min preset button — it's selected by default when you open the page. Then press Start. The circular ring will count down and a beep will sound at zero.

Can I set a custom time like 7 minutes 30 seconds?

Yes. Use the Custom input fields to type any minutes and seconds value (e.g. 7 minutes, 30 seconds), then press Start. The preset buttons will deselect automatically.

Does the timer work if I switch tabs?

Yes. The timer uses the real system clock, so it keeps accurate time in the background. When you return to the tab you'll see the correct remaining time. The beep will play when you're back on the tab if the timer finished while you were away.

Can I use this as a stopwatch for running?

Absolutely. Switch to the Stopwatch tab, press Start when you begin your run, and use the Lap button to record split times at each km or mile. All laps are listed below the stopwatch and can be copied to clipboard.

Is there a sound when the timer hits zero?

Yes — a short beep plays when the countdown finishes. Make sure your device is not on silent and your browser tab is not muted. The sound is generated entirely in the browser using the Web Audio API — no audio file is downloaded.
