Common questions

Can I use this for a timed test or quiz section?

Yes — set 30 minutes, share the link, and every device shows the identical time remaining, which is the whole point of a fair shared clock.

What if I need to stop early?

There's no live pause pushed to other viewers yet — if plans change, the simplest fix is to start a new countdown and re-share the fresh link.

Does this work on a projector as well as phones?

Yes — use Fullscreen mode for a large, high-contrast display, or the Light style specifically if the room is brightly lit.
