Presentation Timer — Know How Long Is Left Without Checking Your Watch
A countdown that lives outside your slides, on a screen only you need to look at. Set it in under a minute, glance at it while you present, and finish on time.

Why not just put a timer in your slides?
A timer built into a deck ties your timing to one file and one machine. It cannot be paused when a question arrives, it disappears the moment you leave the slideshow, and changing it means editing the presentation. Keeping the countdown on a separate screen solves all three: your deck stays exactly as you built it, the timer keeps running through app switches and screen sharing, and you can change the duration on the day without opening the file.
Rehearse against it, not just present with it
Most talks that overrun do so in a specific place — an example that grows in the telling, or a section the speaker knows too well. Running your talk against segmented timings a couple of times tells you exactly where the time goes, which is far more actionable than discovering at the end that you were five minutes over. Set up segments for the opening, each main point, and the close, then watch which one moves.
Reading the colours instead of the numbers
Reading digits requires focus you do not have spare while speaking. Colour does not: green for most of the talk, amber at roughly 20% remaining, red in the final seconds. You will register the change in peripheral vision and adjust your pace without the audience noticing you looked. If the timer is on a shared display, your audience picks up the same signal, which quietly does the work of the moderator.
Frequently Asked Questions
How do I see a timer while I am presenting?
Open the countdown on a device you can glance at without breaking eye contact — your phone on the lectern, a tablet at the back of the room, or a second monitor turned towards you. Because the timer runs as its own page rather than inside your slides, it stays visible no matter what your deck is doing, and it survives switching applications, exiting full screen, or someone else taking over the shared screen.
Does this change my slides in any way?
No. The timer is completely separate from your presentation software, so your deck stays exactly as you built it. This is the main practical advantage over a timer embedded in a slide: you do not have to rebuild anything, it works with any presentation tool, and you can change the timing on the day without touching the file.
Can I use it to rehearse before the real thing?
Yes, and this is where most of the value is. Run your talk against the timer a couple of times and you will learn where you actually lose time, which is almost never where you expect. If you split the talk into segments — opening, main points, demo, close — you can see which section overruns rather than only discovering at the end that you are five minutes long.
Will the countdown turn red or warn me near the end?
It changes colour as you approach the end: green for most of the talk, amber at around 20% remaining, and red for the final seconds. This is deliberately readable at a glance from a distance, so you can register how you are doing in peripheral vision instead of stopping to read digits.
What if I need to pause for a question?
Pause the countdown and resume it when you are ready. If the question turns into a longer discussion and you need more time overall, you can adjust the remaining time while the timer is running rather than resetting and losing your place.
Do I need to install anything or sign up?
No. It runs in a browser, with no download and no account. That matters when you are presenting on a venue or client machine where you cannot install software, and it means you can set the timer up on your phone in the minutes before you go on.
