Stopwatch

Stopwatch makes it simple to time anything. Because it runs entirely on your own device, nothing you use is uploaded anywhere — and you can run it as many times as you like, always free.

What is Stopwatch?

Stopwatch is built for anyone who needs to time anything without downloading software or signing up. Deadlines, ages, time zones and timers come up in work and life all the time. Stopwatch solves that in one click, right in your browser — and because the work happens on your own device, it's both instant and private.

How to use Stopwatch

1. Click “Open Stopwatch” to launch the tool.
2. Enter your numbers in the fields.
3. Read the result — it updates as you type.
4. Tweak the values to compare different scenarios.
