Free Online Stopwatch With Time Laps
Online Stopwatch and Lap Timer
Welcome to our high-precision online Stopwatch, a versatile and user-friendly tool for all your timing needs. Whether you're an athlete tracking your performance, a student conducting an experiment, a chef perfecting a recipe, or simply need to measure a time interval, our digital chronometer provides accurate and reliable results down to the millisecond. This tool combines essential features like start, stop, reset, and lap/split time recording into a clean and intuitive interface that works seamlessly in your browser.
How to Use the Online Stopwatch
Our stopwatch is designed for ease of use. Here is a step-by-step guide to its functions:
- Start: Click the "Start" button to begin timing. The display will immediately start counting up from zero.
- Stop/Pause: To pause the timer, click the "Stop" button (the "Start" button changes to "Stop" once running). The time will freeze, allowing you to resume later. To resume, simply click "Start" again.
- Lap: While the stopwatch is running, click the "Lap" button to record a specific time interval without stopping the main timer. This is perfect for timing laps in a race or stages of a project. Each lap time, along with the overall time, will be recorded in a list below the main display. This feature is also known as a "split timer."
- Reset: When the stopwatch is stopped, click the "Reset" button to clear the current time and all recorded laps, returning the display to "00:00:00.000".

Frequently Asked Questions (FAQs)
What is the difference between a lap time and a split time?
In the context of our stopwatch, we use the terms somewhat interchangeably. Technically, a "split time" is the total elapsed time from the start to a specific point (what we list as "Overall Time"). A "lap time" is the time taken to complete one specific lap or segment. Our tool clearly displays both for each recorded lap, giving you a comprehensive breakdown of your timing session.
Does the stopwatch keep running if I switch to another tab or minimize the browser?
Yes, it does. Our stopwatch uses a time calculation method based on the system clock, not on browser-dependent intervals that can slow down in the background. This means the timer will remain accurate even if the page is not active. When you return to the tab, the displayed time will correctly reflect the total elapsed time.
Can I export the lap times?
Currently, the tool does not have a direct export feature. However, since the lap times are displayed as standard text, you can easily select, copy (Ctrl+C or Cmd+C), and paste the data into any spreadsheet application (like Excel or Google Sheets) or a text document for further analysis or record-keeping.
