Rostrum - Speaker Timer

Rostrum shows a speaker how much time is left, as a clock large enough to read
from the back of the room — or from a phone propped on the podium.

The background changes color at times you choose. Green while there's plenty
left, amber when it's time to move on, red when it isn't. You decide how many
stages there are and exactly when each one starts — most timers give you three
fixed colors and no say in the matter.

SILENT BY DESIGN

No chimes. No alerts. No notifications. Not "sounds turned off by default" —
Rostrum contains no code that can make a sound. Your audience never knows the
timer is there.

THE CLOCK IS THE CONTROL

No buttons over your countdown. Tap to start or pause. Pause it and the clock
becomes the editor: swipe with one finger to adjust seconds, two fingers for
minutes, three for hours. A running clock refuses those swipes on purpose — a
hand steadying the phone should not be able to rewrite a talk in progress.
Pinch in to leave. A one-time overlay teaches the gestures, and a quiet line
along the bottom of the clock keeps the key ones in view whenever the clock is
stopped. Mid-talk, nothing but the time.

BUILT FOR WHOEVER IS RUNNING THE ROOM

Changing a talk length takes one tap. Set your common slot lengths once — 5,
15, 30, 45 minutes, whatever your event uses — and switch between speakers
instantly.

ON A BIG SCREEN WHEN YOU NEED IT

Connect a display with AirPlay or USB-C and the clock fills it while your
phone becomes the remote: start, pause, and adjust from your hand while the
speaker watches the screen.

WHEN TIME RUNS OUT

The screen turns red and flashes briefly, then counts upward so a speaker can
see exactly how far over they are. Impossible to miss, impossible to mistake
for anything else.

DETAILS THAT MATTER ON STAGE

• The screen never dims while the clock is up
• A phone call or a lock screen never stops the countdown — the full time is
there when you come back
• Digits never jitter or shift as the numbers change
• Text color adapts automatically so it stays readable on any background
• Remembers your setup between launches
