Easy launch and maximum benefit

The 105-minute timer makes it easy to track the remaining interval and is suitable for a variety of tasks. Control is done in one click — the start, pause, and reset buttons are available. In a separate settings menu, you can select a suitable sound signal, adjust the volume, or turn off the sound altogether.

The interface adapts to any device-from a smartphone to a large computer screen. The full-screen feature hides minor elements and allows you to focus on time. The timer continues working correctly even when you change the tab, and the exact end time is duplicated under the main countdown in the usual format.
