878 seconds
Open the timer for 878 seconds and immediately start counting down. The interface adapts to any screen size, and an audible alert will alert you when the time is up. Sound settings are available in a separate menu, where you can easily replace the ringtone or turn off the alarm altogether.
Full-screen mode is useful during performances, master classes, or training sessions when it is important to see the timer from afar. Large numbers and concise design allow you to focus on the case.
Seconds are converted to minutes automatically and displayed next to the main counter. This saves time on calculations and makes planning more visual.
