612 minutes
A 612-minute timer shows how much time is left to complete with seconds, and supports simple operation: start, stop, and reset work instantly. The volume of the audio signal is adjustable, and the sound itself can be selected in a separate menu from the list or completely turned off. There is also a button to switch to full screen mode.
The interface is displayed correctly on all devices. For clarity, the standard time format is duplicated under the main counter, and the built-in converter calculates the equivalent of 612 minutes in hours and seconds. Even when switching between tabs, the countdown continues accurately and smoothly.
