Conference Timer: Keep Every Speaker on Schedule

The short answer: at a multi-speaker event, the easiest way to keep the run sheet on time is a visible countdown your AV operator or moderator shows over each speaker's slides. SlideTimerApp floats a timer on the screen, set to each speaker's slot; the digits turn red as time runs low, an alarm sounds at zero, then it counts up showing how many minutes over (e.g. +2:15) with reminder beeps — so speakers trim their material and focus on the main point.

The problem: events drift off the run sheet

Conferences, seminars, town halls and company-wide work meetings all run on a tight run sheet. But one speaker overrunning by five minutes pushes back everyone after them, eats into breaks, and squeezes the sessions that matter most. Reminding speakers verbally is awkward and easy to ignore. A timer everyone can see takes the pressure off the organiser and makes the schedule self-enforcing.

How an AV operator runs the timer over each deck

This is the key idea: the speaker doesn't manage the clock — the person running the booth laptop does. Speakers hand over their slides; the operator presents them and floats the timer on top.

  1. Open the speaker's deck. On the booth/projector laptop, open the handed-over presentation and start the Slide Show.
  2. Float the timer on top. Open SlideTimerApp, set the speaker's allotted minutes from the run sheet, and pin it so it stays above the slides. Drag it to a corner and resize so the room can read it.
  3. Start when the speaker begins. Press Space the moment they start talking. Press it again to pause for questions if needed.
  4. Let the warnings do the work. Red digits near the end, an alarm at zero, then an overtime count-up — the operator never has to interrupt.

Why the overtime count-up matters most

A plain countdown stops at 00:00 — but real events don't. The most useful behaviour is what happens after time runs out. SlideTimerApp keeps counting up, showing +2:15, +3:40 and so on, with periodic reminder beeps. That single number does something a silent stop can't: it makes overrun visible and undeniable. Speakers see exactly how far over they are and start cutting — skipping a sub-point, jumping to the conclusion, focusing on the main message instead of reading every slide.

Real scenario: at a company-wide work meeting where every department presents, the AV assistant shows the timer over each deck. When a presenter passes their slot, the screen reads +1:30 and beeps — and they instantly tighten up and get to the point. The whole event stays on the run sheet without the host having to play bad cop.

Also a stage timer and show timer

The same setup works for any live production that runs to a cue sheet — a stage timer for conferences and award nights, a show timer for theatre, church services and broadcasts, or a session timer for panels and workshops. The operator floats the big countdown on a screen the speaker or performer can see, and the overtime count-up keeps the whole show on cue.

Frequently asked questions

How do event organisers keep speakers on time?

The simplest way is a visible countdown the audience and speaker can both see. At many events the AV operator or moderator runs a timer over each speaker's slides on the screen, set to that speaker's slot from the run sheet. A warning colour, an alarm at zero, and an overtime count-up keep every session on schedule.

Does the timer count up after time is up (overtime)?

Yes. When the countdown reaches zero, SlideTimerApp sounds an alarm and then keeps counting up, showing how many minutes and seconds the speaker is over (for example +2:15), with periodic reminder beeps. Seeing they are over time prompts speakers to trim and focus on the main point.

Can a moderator or AV operator run the timer over the speaker's slides?

Yes. SlideTimerApp is a separate always-on-top window, so whoever runs the booth laptop can float it over each speaker's deck, set the slot length, and start it when the speaker begins. The speaker just presents; the operator controls the timer.

Is there a sound when time is nearly up and when it is over?

Yes. The digits turn red as time runs low, an alarm plays at zero, and reminder beeps continue during overtime. You can adjust the warning point and the overtime reminders in settings.

Can I use it as a stage timer or show timer?

Yes. SlideTimerApp works as a stage timer or show timer for any cue-driven event — conferences, panels, theatre, church services and broadcasts. The operator floats the big countdown on a screen the speaker or performer can see, with a warning colour, an alarm at zero, and an overtime count-up to keep the show on cue.
