Online timer and stopwatch: manage your time efficiently

An online timer is an essential tool for managing your time on a daily basis. Whether you're cooking a meal, studying for an exam, practising the Pomodoro technique or timing a workout, our free timer lets you set a precise countdown with a sound alarm to notify you when time is up.

The advantage of our tool is the ability to run multiple timers simultaneously. For example, you can monitor the cooking of several dishes at once, manage multiple tasks in parallel, or alternate between different work sessions. Each timer displays its remaining time in the browser tab title, allowing you to track their progress even when browsing other pages.

The integrated stopwatch is perfect for measuring elapsed time: sports training, productivity tracking or performance timing. The "lap" function lets you record intermediate times without stopping the main stopwatch, ideal for running, cycling or any activity requiring segment measurements.

No installation is required and the tool works entirely in your browser. Once the page is loaded, you can even use it offline. Timers continue to run in the background, even if you switch tabs or minimise your browser, and the sound alarm will alert you at the right time.
