Reliable assistant for accurate counting

The 308-hour timer shows how much time is left to complete, and is ideal for tasks that require a long countdown. The control panel includes basic buttons - "Start", "Pause", "Reset". At the end of the countdown, the selected signal is played, which can be replaced, adjusted in volume, or turned off. The timer also informs you about the duration of 308 hours in days, minutes, and seconds thanks to the built-in time converter.

The interface adapts to any screen — be it a mobile device or a desktop monitor. You can activate full-screen mode for maximum convenience. Even when running in the background, the timer continues to count down, and the current time remaining is always visible in the tab title.
