Online Stopwatch with Laps — PWA App

A free stopwatch right in your browser — no app installation or registration required. This is a PWA app: you can add it to the home screen of your smartphone or computer and use it offline. Millisecond precision, automatic state saving, and convenient lap tracking make it an indispensable tool for sports, studying, and professional use.

How to Use

Press «Start» to begin counting. The «Lap» button records the current split time and immediately starts counting the next lap. «Stop» pauses the stopwatch — it can be resumed by pressing «Start» again. The «Reset» button resets everything and clears the lap list. Close or refresh the page — the stopwatch will remember its state and continue from where it left off. As a PWA app, the stopwatch can be installed on your device and launched even without network access.
