How to Use: Online Stopwatch

The free Online Stopwatch allows you to record split and lap times and edit them without interrupting the timer. You can also save your timings in a text file.

Getting Started

How to use the Stopwatch

  • Click on the Play button to start the Stopwatch.
  • To add splits, click on the Split button. You can add as many splits as your task requires.
  • To pause or stop the Stopwatch, click on the Stop button. The Stopwatch will save your time and begin from the same point you pause it.
  • To stop and reset the timer, click on the Reset button.

Start alerts

Start alerts notify you that the Stopwatch is about to start running.

To set the alert, click on the Set start alert and sounds link. In the menu that appears, tick the Start alert box and make a selection in the drop-down menu next to it. You can choose to set the start alert time to 3, 5, or 10 seconds. This means that the Online Stopwatch will count down 3, 5, or 10 seconds before it starts running.

If you need an acoustic signal, you can add it by enabling the Start alert sound option and selecting a sound in the drop-down menu.

Interval sound

Click on the Set start alert and sounds link and tick the Interval sound box if you would like to be alerted at regular intervals while the Stopwatch is running. The alerts will be repeated at the interval you specify.

For example, if you enter an interval of 1 minute and 30 seconds, the sound will be played at 1:30, 3:00, 4:30, and so on.

Specific time sound

Use the Specific time sound option if you would like to be alerted after a certain time span has elapsed. Simply click on the Set start alert and sounds link, tick the box and enter the number of hours, minutes, and seconds.

To add another specific time, click on the plus (+) symbol next to Specific time sound. To remove one of the times, click on the cross (x) next to it.

Labeling and editing the results

The Online Stopwatch automatically records all your split times and calculates your lap times for the session. To look at them, click on More Detail on the bottom-right side of the timer. You can only see this button after you have recorded at least one split or paused the timer.

Use the text fields to label each split time with a title of your choice. Rearrange them in the opposite order by clicking on Reverse. To delete a split, click on the cross (x) at the end of the row.

Saving the results as a text file

Please note that the Online Stopwatch will not save your timings if you click on reset or refresh the page.

To save and share your splits, laps, and total times, you must click on Export results as text. This will create a text file with all your timings that you can download, save, or share.

FAQ: Troubleshooting

Why do the sounds not work?

If you followed the above instructions to set up a start alert, interval sound, or specific time sound and you don't hear any of them while you run the Stopwatch, please first make sure that your system volume is turned up and that your speakers are plugged in and switched on. You can test this by clicking on the Set start alert and sounds link and then on any of the Test links.

If are using an older version of Internet Explorer, please make sure to enable Flash.

If you still don't hear any sound, we would like to hear from you. Please let us know what kind of device, browser, and browser version you are using.

Why is the local time in the results is wrong?

The Online Stopwatch uses your computer's time zone to display local times. If the times shown in the Stopwatch do not reflect your local time, you will have to select your time zone in your operating system. Don't forget to enable Daylight Saving Time switches if that option is available for your location. Otherwise, the times will be off by one hour for part of the year.

Please note that your system's time zone setting is separate from the current time shown on your computer, so you may be using a different time zone even if your computer's time looks correct. If that is the case, the local times in the Stopwatch will not be in your local time.

Why can't I add a second stopwatch?

While it is only possible to have one Stopwatch per page, you can set up more than one by opening the Stopwatch page in multiple browser windows. Please note that all Stopwatch windows you open in the same browser will have the same alert and sound settings. To set up multiple Stopwatches with different settings, please open them in different browsers.

By the way, our Online Timer allows you to set up multiple timers on the same page.
