Canonical page: https://nepocore.com/tools/stopwatch/

Measure elapsed time, pause and resume, and record lap totals with intervals. Timing uses the browser’s monotonic clock.

## How to use it

1. Choose or enter the content for this tool.
2. Start the action with the settings you want.
3. Review the result before copying, sharing or continuing.

## Example

Time a practice task and capture a lap each time you finish one section.

## Limits and checks

The stopwatch resets when you leave the tool or reload the page. It is not intended for precision scientific timing.

## Access and processing

Free to use without an account. Interactive processing requires JavaScript in a modern browser. Input is processed in the browser rather than sent to a processing server. Optional browser storage is not a synchronized account.
