55 minutes
A 55-minute timer counts down the set interval to within a second and helps you conveniently control the time. Thanks to the built-in converter, you will immediately see the duration of 55 minutes in seconds. Control is implemented using simple buttons that allow you to quickly start, stop or reset the timer. The sound notification is adjustable — you can select the signal or turn it off completely.
The full-screen mode feature makes the timer visible and convenient when used in classrooms or in groups. The interface is responsive and works equally well on smartphones, tablets, and computers. Even when you go to another page, the countdown remains active, and the current time is visible in the browser tab title.
