Fullscreen Presentation Countdown Timer

Free fullscreen countdown timer with digits sized to fill a projector or large monitor edge-to-edge. Designed for presentations, lectures, sport breaks, classroom timers, and meeting rotations. Quick presets (5 to 60 minutes) plus precise minutes/seconds custom input. Audible beep on each of the last 10 seconds and a longer tone at zero. After zero the counter goes negative so you can see overshoot.
