30-Minute Timer
A clear thirty-minute countdown for talks, breakout sessions, tests and lunch breaks.
The short answer: press Start for a 30-minute countdown with an alarm at zero. To put a 30-minute timer on top of your PowerPoint while you present, download SlideTimerApp and tap the 30-minute preset — it floats over your live Slide Show instead of living in a browser tab.
What a 30-minute timer is good for
- A 30-minute conference talk or breakout session
- Quizzes and test sections in class
- Lunch and coffee breaks at events
- A lecture segment before an activity
Pacing a 30-minute talk
A thirty-minute slot is usually about 25 minutes of talk and five for questions. With the countdown floating over your slides you can check your pace at each section break without looking at a phone. If you run long, the SlideTimerApp desktop app keeps counting up into overtime, so you know exactly how far over you are. See the presentation timer guide for more on pacing a talk.
How to use a 30-minute timer in PowerPoint
This page is great for a quick countdown on your screen. But a browser tab cannot stay on top of a full-screen Slide Show. For that, use the free overlay app:
- Download SlideTimerApp. Open the free portable Windows app.
- Tap the 30-minute preset. Or type any minutes and seconds.
- Pin it on top and present. Press F5 — the 30-minute countdown floats over your slides and rings at zero.
