Classroom Timer is a handy Chrome extension developed by Turbo Logic. It opens a new tab with a visual timer featuring a random gradient background. This simple yet effective tool allows teachers to start a timer quickly without the need to visit search engines or ad-filled websites.

With just a click on the extension's icon, a new timer page opens, displaying a live countdown to show students how much time they have left. Additionally, a notification bar pops up upon timer completion. The interface offers convenient options such as Start to begin the timer, Pause to pause and resume, Reset to zero out input values, and Cancel to close the tab.
