Online Timer
An online timer is a web tool that counts down a set amount of time and alerts you when it reaches zero. No app or installation is needed—just open the page in your browser. Set a timer for hours, minutes, or seconds; when the countdown finishes, the timer rings and you can stop or snooze it.
Use an online timer for cooking, exercise, work breaks, study sessions, meetings, or any activity where you need to track time. The large display makes it easy to see the remaining time from a distance. You can customize the alarm sound and message in settings, and your last-used timers are saved for quick access.
