Accurate measurement of duration in the browser

A timer for 100 minutes, after starting, displays how much time is left until the countdown ends, and allows you to control long-running processes. At the end, a signal will sound, which you can choose from the suggested options in advance, adjust the volume, or turn off altogether. All actions-start, pause, and reset-are performed with a single click and are intuitive.

The built-in time calculator automatically calculates the equivalent of 100 minutes in seconds and hours for ease of use. The timer can be easily expanded to full screen, hiding all possible distracting elements. The interface is adaptive and adapts to the screen of your smartphone, tablet, or computer. Even when switching tabs, the countdown continues to work correctly.
