Reliable hourly timer for all occasions

The online timer counts down to zero for 1 hour and shows the remaining time in large numbers. The built-in converter automatically converts 1 hour to minutes and seconds, helping you quickly estimate the duration. The interface is intuitive: the start, pause, and reset buttons respond instantly. If necessary, you can expand the timer to full screen to focus on the task at hand. The end of the countdown is accompanied by the selected sound signal — you can adjust the volume or completely mute the sound.

The timer adapts to any device-from a smartphone to a large monitor, maintaining accuracy even when switching to another tab. The remaining time is duplicated in the browser header, so you don't miss the end point when you complete multiple tasks at the same time.
