Full-Screen Timer

A simple full-screen timer for presentations

Set a clean, distraction-free countdown for talks, workshops, classroom activities, and meetings. The large circular progress ring and oversized digits stay readable from across the room, and the Fullscreen button turns any screen or projector into a dedicated timer.

Choose Count down to run for a set length of time — just enter the minutes and seconds. Choose Finish at a clock time to count down to a specific time of day, such as the end of a break; the timer shows both the current time and when it finishes.

Keyboard shortcuts keep you in control while presenting: press F to toggle fullscreen, Space to pause or resume, and Esc to bring the controls back. The timer follows your light or dark theme automatically.
