Accurate countdown without unnecessary settings

The timer shows how much time is left until the end of the interval, and directly in the interface shows how many 129 minutes in hours and seconds. The Start, Pause and Reset buttons allow you to instantly control the process, and the sound settings allow you to choose a ringtone or completely mute the sound. Full-screen mode is available in one click and makes the countdown more visible even from afar.

The interface adapts to the device screen and works correctly even in the background tab, without losing accuracy. For convenience, the remaining time is duplicated under the timer in the standard familiar format.
