The 561-minute timer shows the remaining time with seconds and allows you to track the entire interval until the end. The interface includes basic controls — start, pause, and reset buttons. It is possible to expand the timer to full screen to fully focus on the time. At the end of the countdown, a melody is played, and the volume can be adjusted or muted if necessary.
