Online Stopwatch & Timer — Free Online Tool

This page provides three related timing tools: a stopwatch that counts up with lap recording, a countdown timer that counts down to zero with an alert, and an interval timer that alternates between work and rest periods.

Lap timing on the stopwatch is the feature that distinguishes it from just watching a clock. Recording splits without stopping lets you compare segments against each other — which lap was slowest, whether pace held or drifted — which is the actual question in training, in timed drills, and in any repeated process you are trying to make faster.

The countdown is the everyday one: cooking, presentations kept to time, timed exam practice, and anything that needs an alert rather than monitoring. The interval timer covers structured training formats — HIIT, circuits, Tabata — where the value is not having to watch a clock at all while working.

One practical caveat for any browser-based timer: mobile browsers aggressively throttle background tabs and may suspend a page entirely when the screen locks, which can delay or suppress an alert. For anything where missing the alert matters, keeping the screen on and the tab in the foreground is the reliable approach — or using a device alarm instead.

Timing runs in your browser with no account, no ads interrupting the countdown, and nothing transmitted.

Our Online Stopwatch & Timer is completely free to use with no signup required. For this tool, processing runs in your browser — your files and data stay on your device and are not uploaded to our servers.
