Countdown Timer FAQ

How do I set a countdown time?

Use the Set inputs (hh:mm:ss) and press Apply, or tap a preset like 5m, 10m, 25m, or 1h. Then press Start.

What is Deadline mode?

Deadline mode counts down to a specific clock time (for example 14:30). If that time has already passed today, the timer automatically counts down to the same time tomorrow.

What is Wall mode used for?

Wall mode hides the on-screen controls so the countdown stays clean and readable on TVs, projectors, or across a room.

Can I use a photo background?

Yes. Click Background to choose an image from your device. Click Clear to remove it. The image is stored on your device for convenience.

What keyboard shortcuts are supported?

Space starts/pauses, R resets, F toggles fullscreen, W toggles wall mode, and S toggles sound.
