Presentation Mode

Presentation Mode is a distraction-free, full-screen timer for keynotes, conference talks, webinars, sales demos and TED-style lightning talks. The screen shows one thing: a large, high-contrast countdown of the time left in your slot, readable from the back of a room or across a stage. There is no navigation bar, no ads and no notifications — just the number a speaker needs to stay on time.

Set the length of your slot, press Start, and glance at the timer whenever you need it. Pause and resume with the on-screen button if you stop for a question, and reset to run the same length again for the next speaker. The fullscreen button hides everything but the digits, and when the countdown reaches zero an alarm plays — a clear, friendly cue that your time is up.

Speakers use it for almost every kind of timed talk: ten-minute lightning talks, twenty-minute conference sessions, forty-five-minute keynote slots and hour-long webinars. Sales teams use it as a demo timer so a pitch fits the booked window. Trainers and lecturers keep it on a second screen so they always know how long is left without checking a watch.

The layout is built for real rooms: a dark background with near-white digits stays readable under stage lighting, through a projector and through eyeglasses. It never shows ads — a paid corporate webinar should not have ad breaks — and it runs the same accurate, browser-based code as the rest of ClockAura, with no account and no sign-up.

A common setup is to open Presentation Mode on a second monitor facing you while your slides run on the main screen. For teaching in front of a class, the related [Classroom Mode](/classroom-mode) gives the same chromeless full-screen layout, and for focused solo work the [Pomodoro timer](/pomodoro-timer) breaks the day into timed blocks.

About Presentation Timer Mode

Presentation Mode is a speaker's clock — a large, glanceable timer you can keep on a confidence monitor or in a corner of the projected screen while you talk. It helps you land a talk on time without staring at a watch or losing your place. The layout is clean enough to sit beside slides and bold enough to read from the stage.

When to use Presentation Mode

Conference talks and lightning talks with a hard time slot.
Webinars and online workshops where you cannot overrun the booked hour.
Product demos and sales pitches that have to fit a fixed window.
Q&A sessions and panels where each answer or speaker gets a set time.
Workshop segments and breakout activities that need a visible limit.
Rehearsing a talk against the real time budget before the event.

How to use Presentation Mode

Set your slot length on the Countdown Timer (for example 18 or 40 minutes).
Open /presentation-mode for the clean speaker layout.
Put it on your confidence monitor, a second screen, or a corner of the shared screen.
Use Space to pause during applause or questions, then resume.
Watch the colour change near the end as your cue to start wrapping up.

Tips for using Presentation Mode

Rehearse with the same timer you will use live so your pacing matches the real budget.
Set the timer to your speaking time, not the whole session, and leave a few minutes for questions inside the slot.
On a dual-screen setup, keep Presentation Mode on the monitor only you can see.
Pick a gentle end sound, or mute it and rely on the colour change, so nothing interrupts your close.
Bookmark it next to your slides so it is one click away before you go on.
