Enter how long your talk is and how many slides you have, and the timer gives each slide its share. While you present it counts down the current slide, shows the time left for the whole talk and tells you at a glance whether you are ahead of plan, on track or falling behind.

Times are m:ss or plain minutes. In the list, end a line with a time (e.g. Demo 5:00) to fix that slide's length; lines without a time share what is left equally. When the list has lines, it sets the number of slides.

How to use the Presentation Timer
Enter the total talk time and the number of slides. Add Q&A time if part of your slot is for questions.
Optionally list your slides, one per line. End a line with a time such as Demo 5:00 to fix its length; the other slides share the rest.
Check the slide plan table to see each slide's length and start time.
Press Start talk as you begin, then press Next (or the right arrow) each time you change slides. Open the fullscreen speaker view on a second screen or device.
Watch the pacing badge: blue means ahead, green on track, amber behind and red over time.
Press End talk to see planned versus actual time for every slide.
Time per slide at a glance
Time per slide = (talk length − Q&A) ÷ number of slides. The table shows the even split for common slots with no Q&A reserved.

Times are rounded down to the second; the timer hands out leftover seconds to the first slides so the plan always adds up exactly to the total.
Reading the pacing badge
Ahead (blue): you reached this slide before its planned start. You have spare time to slow down or take a question.
On track (green): the clock is inside this slide's planned window.
Behind (amber): the slide's window has ended. The figure shows how far behind plan you are, so you know how much to trim.
Over time (red): the whole talk has passed its total length.
Tips for staying on time
Rehearse with the timer and End talk at the finish: the summary shows exactly which slides run long.
Fix short times for quick slides such as the title, agenda and thank-you slides, so the main content gets a realistic share.
Plan for 90 percent. Live talks often run longer than rehearsals; aiming a little under the slot leaves room for questions and technical hiccups.
Mark a cut slide. Decide in advance which slide you will skip if the badge says you are behind at the halfway point.
Frequently asked questions
How much time should I spend on each slide?
Divide the time you have for slides by the number of slides. A 20-minute talk with 10 slides gives 2 minutes per slide; with 5 minutes reserved for Q&A it is 15 minutes over 10 slides, or 1:30 each. Title and closing slides usually need less, so give them a fixed short time and let the others share the rest.
How does the timer decide if I'm ahead or behind?
Each slide has a planned window, for example slide 3 from 4:00 to 6:00. If you reach slide 3 before 4:00 you are ahead by the difference; if you are still on it after 6:00 you are behind by the time past 6:00; in between you are on track. Over time means the whole talk has run past the total.
Can I use my presentation clicker with it?
Most clickers send Page Down / Page Up or arrow keys, which this timer understands when its tab has focus. Usually the presentation itself has focus, so the simplest setup is to run the timer on a second device, such as a phone or tablet in front of you, and press Next there.
What happens if I go back to an earlier slide?
Press Prev or the left arrow. Time spent on a slide is added up across visits, so the summary shows the true total for each slide even if you returned to it.
Can I set different times for different slides?
Yes. Type one slide per line in the slide list and end a line with a time in m:ss or minutes, like "Intro 0:30" or "Demo 5 min". Lines without a time share whatever is left of the total equally.
How many slides should a talk have?
There is no fixed rule. Many speakers plan on roughly one to two minutes per content slide, while fast-paced formats such as Ignite and PechaKucha use 20 slides that advance every 15 or 20 seconds. Use the per-slide time the timer shows to judge whether your deck is too long.
Is anything uploaded?
No. The timer runs entirely in your browser, and your settings are stored only in this browser's local storage.
