600 minutes
This 600-minute timer keeps an accurate countdown with seconds and allows you to control it with one touch. The timer functionality includes start, pause, and reset buttons, as well as support for an audio notification. The alarm setting is available — you can choose a ringtone or turn off the sound completely. The full screen allows you to conveniently monitor the timer even from a distance.
The built-in converter displays the duration of 600 minutes in hours and seconds. The current timer state is duplicated in the browser tab header, which is convenient when working with multiple windows.
