144 minutes
A 144-minute timer displays a countdown on the screen and accurately counts down to the last second. The built-in time converter shows the equivalent of 144 minutes in seconds and hours, helping you estimate the duration in other units. Simple operation through the main buttons allows you to start, stop or reset the countdown in one click. At the end of the countdown, the selected audio signal sounds with an adjustable volume.
The interface is responsive and equally convenient on phones, tablets, and PCs. One click puts the timer in full-screen mode, hiding minor interface elements. The timer continues to work accurately when switching between pages, and the remaining time is duplicated in the browser tab header.
A long 144 minutes timer is useful for classes, trips, work shifts, slow-cook recipes, and any scenario where you need to time a long interval. The browser keeps the countdown accurate even when you switch tabs.
