What is a presentation timer?
A presentation timer is a countdown built for the person talking. It shows how much time you have left, and it changes color at the moments that matter: green while you're on time, yellow when it's time to start wrapping up, red for the last stretch. When time runs out, this one keeps counting, so +0:37 tells you that you went 37 seconds over. Some people call it a speaker timer or a talk timer. Same job.
The green-yellow-red idea is older than laptops. Conference chairs hold up colored cards from the front row. Speech clubs put three lights on the lectern. Debate timekeepers flash fingers. They all do the same job: tell the speaker where they are without making them do math mid-sentence. "I started at 2:14 and I have 20 minutes, so…" is not a thought you want to have while you're also trying to land a point.
You need a speech timer any time the slot is fixed and someone else cares about it. A 5-minute lightning talk. A 20-minute conference session with a Q&A buffer. A class presentation graded on length. A 90-second pitch. A wedding toast that should not become a keynote. Running 3 minutes over in a 20-minute slot means 15% of your talk came out of the next speaker's time.
How to use the presentation timer
- Tap a talk length: 5, 10, 15, 20, 30 or 45 minutes. For anything else, type it into Minutes and Seconds. A 7½-minute pitch is 7 and 30.
- Check the cues. Yellow at and Red at count minutes left, not minutes gone. The defaults are yellow at 2 and red at 1. Pick Off to drop either one.
- Press Start (or the Space bar) as you say your first word.
- Press Full screen (or F) and turn the screen toward the stage.
- Talk. Watch the color, not the digits. The caption above them says the same thing in words: On time, Wrap up, Last minute, Over time.
- At
0:00the clock keeps going:+0:01,+0:02. Press Pause when you finish, and R to reset for the next speaker.
The setup fields lock while the clock runs, so a stray tap can't change your talk length halfway through. Changing any setting while paused sends the clock back to the start.
How the color cues are worked out
Every reading comes from one number: the seconds left, rounded up to the next whole second. The color is read from that same number, so the screen and the digits can never disagree.
Seconds left = talk length − time elapsed, rounded up
0 or less → over · at or under the Red cue → red · at or under the Yellow cue → yellow · otherwise → green
Rounding up matters. With 4 minutes and half a second left, the screen reads 4:01, not 4:00. So 0:00 only appears when time really is up, and the panel turns yellow the moment 4:00 shows, not a beat before it.
A worked example: the 20-minute conference slot
Say you set 20 minutes, yellow at 4 minutes left and red at 2. Here's what the screen shows as the talk goes on:
| Time elapsed | Screen shows | Color | Caption |
|---|---|---|---|
| 0:00 | 20:00 | Green | On time |
| 15:59 | 4:01 | Green | On time |
| 16:00 | 4:00 | Yellow | Wrap up |
| 18:00 | 2:00 | Red | Last 2 minutes |
| 19:59 | 0:01 | Red | Last 2 minutes |
| 20:00 | 0:00 | Deep red | Over time |
| 20:37 | +0:37 | Deep red | Over time |
| 22:05 | +2:05 | Deep red | Over time |
The bar under the digits drains with the talk. At yellow in this example it's one-fifth full. It empties at 0:00 and stays empty through overtime, because there's nothing left to drain. Overtime counts in whole seconds, so it reads 0:00 for the first second past the end, then +0:01.
Cue settings for common talk lengths
A good yellow cue lands about 15–25% from the end. That's where you'd start your close if you were running behind. A good red cue matches how long your ending takes to say: a one-minute summary and a thank-you wants red at 1. These are starting points, not rules. The last column is a script budget at a speaking pace of 130–150 words a minute, which is where most people land when they talk to a room.
| Talk length | Yellow at | Red at | Turns yellow after | Turns red after | Script length |
|---|---|---|---|---|---|
| 3:00 | 1 min left | Off | 2:00 | — | 390–450 words |
| 5:00 (lightning talk) | 1 min left | Off | 4:00 | — | 650–750 words |
| 7:30 (pitch) | 2 min left | 1 min left | 5:30 | 6:30 | 975–1,125 words |
| 10:00 | 2 min left | 1 min left | 8:00 | 9:00 | 1,300–1,500 words |
| 15:00 | 3 min left | 1 min left | 12:00 | 14:00 | 1,950–2,250 words |
| 20:00 | 4 min left | 2 min left | 16:00 | 18:00 | 2,600–3,000 words |
| 30:00 | 5 min left | 2 min left | 25:00 | 28:00 | 3,900–4,500 words |
| 45:00 (keynote) | 10 min left | 5 min left | 35:00 | 40:00 | 5,850–6,750 words |
| 60:00 (workshop) | 10 min left | 5 min left | 50:00 | 55:00 | 7,800–9,000 words |
Notice the short talks drop red entirely. In a 3-minute slot, yellow at 1 minute already is the last minute. A second cue just adds a color change you don't have time to react to. On the longer talks, the gap between yellow and red widens because a keynote's close is longer. You need 5 minutes to take questions, not 60 seconds.
If you've got 20 minutes and a Q&A, set the timer for the talk, not the slot. A 20-minute slot with 5 minutes of questions is a 15-minute talk. Set the speech timer to 15, and let the overtime count tell you how much of the Q&A you ate.
Why most timers let speakers down
Search for a speaker timer and you find three shapes, and each fails in its own way.
The stage-timer platform. It does the job, eventually. First you make an account. Then you pick a plan, because the basics sit behind the paid tier. Then there's per-event or per-seat pricing, a producer console to learn, and a free trial that quietly turns into a subscription. That's the Big Software pattern: a countdown locked behind a contract. You wanted a clock that turns yellow.
The generic countdown page. Big digits and a full-screen button, which is a good start. But the cues are usually fixed or buried in settings, the digits compete with ads, and it stops at 0:00. Stopping at zero throws away the most useful number of the whole talk: how far over you went.
The phone timer. It's already in your pocket. It also dims its screen halfway through a 45-minute talk, and it says nothing until the alarm goes off in front of 200 people.
This presentation timer is the clock and nothing else. No account, no trial, nothing to install. It keeps the screen awake while it runs, using the browser's Screen Wake Lock. It measures real elapsed time instead of counting ticks, so it stays right when you switch to your slides and the browser slows the timer's tab down. And it counts overtime to the second.
Edge cases and limitations
When the timer won't start
The timer refuses setups that can't work, and it tells you which part is wrong. A 1-minute talk with the default cues gets "Yellow is set for 2 minutes left, but the talk is only 1 minute. Pick a smaller Yellow, or Off." A cue equal to the talk length fails the same way: a 3-minute talk can't turn yellow at 3 minutes left, because it would be yellow before you spoke. Red has to be fewer minutes than yellow, so yellow 3 with red 3 gets "Red should come after yellow." A 0-minute talk asks you to set a length first. Talks run up to 180 minutes.
What this talk timer deliberately doesn't do
- No remote control. A timekeeper can't run it from their phone while it shows on yours. That needs a server, and this tool runs in your browser alone. For a timekeeper, just hand them the laptop.
- No agenda or speaker queue. One talk, one clock. Press R between speakers.
- No speech-contest window. Contest rules often light green at the minimum time and red at the maximum, with a pass/fail at the end. That's a different timer. This one counts down to a single end point.
- No flashing at time's up. A strobing screen is an accessibility hazard and rude to the room. The panel turns deep red and starts counting. That's enough.
If something isn't working
If Space doesn't start the clock, click once on the page outside the Minutes box first. Shortcuts switch off while you're typing in a field, so typing "15" never starts anything. If a presenter clicker doesn't pause it, your clicker probably sends Page Down or an arrow key for slides, not Space. On an iPhone, the Full screen button is hidden because Safari doesn't let pages go full screen there; turn the phone sideways and the panel fills most of it anyway.
Related timers and tools
Writing the talk before you time it? Paste your script into the word counter and divide by 130–150 to get your spoken minutes. The reading time calculator gives a quick estimate too, but it assumes silent reading at 200 words a minute. Out loud, add about a third.
Running a room instead of a talk? The classroom timer is built for the back row: a big countdown with a bar and a chime, stopping at zero, for tests and group work. The plain countdown timer covers everything else with an end time. And to see how long a rehearsal actually took, start the stopwatch with no target in mind and read the number when you're done.
Frequently asked questions
How many words is a 10-minute speech?
About 1,300 to 1,500 words, at a speaking pace of 130–150 words a minute. Nerves speed most people up, so if you're close to the top of that range, cut a little. Rehearse once with this timer and the overtime count tells you exactly how much.
Does the chime go off at yellow and red?
No. The chime is off by default, and when you switch it on it plays once, at 0:00. It's a single soft tone about a second and a half long, made in your browser, so there's no sound file to load. The yellow and red cues are silent on purpose. A beep at 2 minutes left tells the whole room you're running long.
How do I use a speech timer to rehearse?
Set your real slot length, start the clock and run the whole talk without stopping. Note where you were when the screen turned yellow, then read the overtime at the end. If it says +1:40, you have 1 minute 40 seconds to cut, and you know roughly which section to cut it from.
Can someone else keep time for me?
Yes, on the same screen. Put the speaker timer in full screen on a laptop facing you, and the timekeeper presses Space to start and pause. Remote control from a second device isn't possible, because that would need a server between the two.
Is my talk information saved anywhere?
No. There's no account, and the presentation timer runs entirely in your browser. Nothing about your talk length or your overrun is sent anywhere. Close the tab and it's gone.
Is a presentation timer different from a countdown timer?
Yes, in two ways. A presentation timer has cues set by time left, so the screen tells you when to wrap up, and it keeps counting past zero. A regular countdown just runs to 0:00 and stops, which is right for an oven and wrong for a speaker.
Is there a pro version with more features?
No. This is the full tool. Microapp builds one tool per job, and each one ships finished, with no pro tier and no feature held back. 10% of every dollar Microapp earns goes to charity, off the top, audited quarterly.
