What Is an Online Stopwatch?
An online stopwatch is a browser-based timer that measures how much time passes from the moment you start it. Instead of counting down from a preset value, a stopwatch counts upward from zero.
Splattermail's stopwatch provides a simple way to measure elapsed time without downloading software or creating an account. You can use it whenever you need a quick timing tool on a computer, smartphone, or tablet.

- Press Start to begin counting elapsed time.
- Press Pause when you need to temporarily stop the clock.
- Press Start again to continue the same session.
- Press Lap while running to save the current elapsed time.
- Use Reset when you want to start a completely new timing session.
- Use Clear laps to remove the recorded lap list.

Stopwatch vs. Countdown Timer
A stopwatch and a countdown timer are both useful for measuring time, but they work in opposite directions.
A stopwatch begins at zero and counts upward. It is useful when you want to measure how long something takes.
A countdown timer begins with a selected duration and counts toward zero. It is better when you already know how much time you want an activity to last.
For example, you can use a stopwatch to measure the length of a workout and a countdown timer to remind you when a 20-minute workout period has finished.
How Accurate Is a Browser Stopwatch?
The displayed stopwatch uses browser timing functions to calculate elapsed time rather than simply adding a fixed amount every time the screen updates. This helps the timer remain consistent when normal browser scheduling causes individual updates to be delayed.
The stopwatch is designed for everyday timing and general measurement. It should not be treated as a replacement for specialized laboratory, scientific, athletic, or professional timing equipment where certified precision is required.
