What is Countdown Timer?
A countdown timer designed to be seen from the back of the room. Choose a preset (1, 2, 5, 10, 15, 30 minutes) or type any time, press Start, and the digits fill the screen with a ring that turns from green to amber to red as time runs out. A short alarm plays at zero when sound is on.
Teachers use it for silent reading and tests, hosts for game rounds, cooks for the pasta, and everyone for the pomodoro they promised to do. Fullscreen hides everything but the timer.
