Timer for 15 minutes

An online timer for 15 minutes counts down to zero and shows how much time is left until completion. For convenience, the interface has a built-in converter that calculates the equivalent of 15 minutes in seconds. Control is implemented through clear start, stop, and reset buttons. Activate full-screen mode and all minor elements will be hidden. The countdown ends with a sound that can be adjusted by volume or turned off completely.

The interface adapts to any device, be it a mobile screen or a desktop monitor. Even when working in other tabs, the timer continues to function accurately, and the time until completion is visible in the browser tab title. This allows you not to lose control of your time, even if you switch between tasks.
