Good to know.

The screen stays on.

While the timer runs, your screen won't turn off. If your browser can't do that, the timer tells you.

Landscape for distance.

Turn your phone and the timer shows only the time and what's on, big enough for the other side of the room.

Every setting is in the link.

Copy the address, send it, done. No account on either side.

Counted against the clock.

Put the phone down or switch tabs and the time is still right when you come back. The browser does pause the beeps in between, though.
