20 minutes
A 20-minute timer counts down the remaining time interval and allows you to immediately find out the equivalent of 20 minutes in seconds. Management is simplified as much as possible — the start, pause and reset buttons are intuitive and work in one click. If necessary, you can enable full-screen mode: it hides everything secondary and leaves only the counter and controls.
The timer accompanies the countdown with an audio signal — You can select the sound in advance and adjust its volume. The interface is equally convenient on a phone, tablet, or large monitor, and when you switch tabs, the countdown continues to work accurately. The current time to completion is shown in the browser tab title, which is convenient when working with multiple windows.
