838 seconds
The timer works completely free of charge right in the browser. When the countdown is complete, you will hear a beep. In the timer settings, you can pre-select the appropriate notification melody and adjust the comfortable volume level.
Full-screen mode is especially useful in situations where you need to keep track of time from a distance. For example, during sports training sessions, when giving a presentation, or while cooking in the kitchen. In this mode, only the timer itself with large numbers is displayed on the screen.
The built-in automatic time converter instantly converts seconds to minutes and displays the result on the screen.
