What is an Online Stopwatch?

An online stopwatch is a user-friendly application that allows you to accurately measure elapsed time. It functions as a digital stopwatch directly in your computer or phone browser, ideal for timing study sessions, work, sports training, or any activity that requires precise timekeeping.

How to Use the Stopwatch?

Using this tool is very simple:

• Press the Start button to begin the timer.
• Press the Pause button to stop the timer when you need a break. The Start button will then become a Resume button.
• Press the Lap button to record a time marker (e.g., finishing a book chapter, a workout set). The lap time and total time will be saved in the "Lap History" table.
• Press the Reset button to clear the entire session and reset the timer to zero.

The lap data can be exported to a CSV file for you to store and analyze your performance by clicking the Export CSV button.

Does the Online Stopwatch work if the browser is closed?

No. The stopwatch will stop if you close the browser tab or window. However, it will continue to run if you switch to another tab or use a different application on your computer.
