A countdown and a stopwatch, big enough for a room
Meetings run long, exercises overrun, and someone always asks how much time is left. A timer everyone can see answers that without anyone having to ask. This one has two modes: count down to zero, or count up from it.
The digits are deliberately enormous and scale to whatever they are shown on, from a phone propped against a mug to a projector at the far end of a hall. There is nothing to install and no sign-up, and once the page has loaded it keeps working with the connection off.
How to use it
- Choose Countdown or Stopwatch at the top.
- For a countdown, tap a preset or type the minutes and seconds you want.
- Press Start. Pause stops the clock without losing your place; Start again picks up where it stopped.
- Reset returns a countdown to its full length and clears a stopwatch back to zero.
- In stopwatch mode, Lap records a split without stopping the clock. Laps list underneath.
Good uses
- Classrooms: timed reading, tests, and the last five minutes of an activity.
- Meetings: a strict slot per speaker, or a timeboxed discussion nobody can quietly extend.
- Workshops and retros: everyone can see the clock, so nobody has to be the person watching it.
- Cooking, exercise, and anything where you want a large number visible across a room.
- Presentations, where a stopwatch at the back tells you whether you are running short or long.
Why it does not drift
Most timers on the web count intervals, adding a second every time the browser tells them a second has passed. Browsers throttle background tabs to save battery, so those timers quietly fall behind, and a five minute countdown can finish a minute late if you looked at your email halfway through.
This one writes down the moment it should finish and then simply asks the clock how long is left. Nothing accumulates, so nothing can drift. Switch tabs for two minutes, come back, and the display is already correct rather than catching up.
Questions people ask
- Does it keep time if I switch tabs?
- Yes. Browsers slow down background tabs, which makes most web timers drift, so this one does not count ticks at all. It records the moment it should finish and compares against the clock, so switching away and back shows the correct time immediately.
- Will it make a sound at zero?
- A short beep, generated in the browser rather than loaded from a file, so it works offline. There is a mute toggle and your choice is remembered on this device. Some browsers block sound until you have clicked something on the page, which starting the timer counts as.
- Can I show it on a projector?
- That is what Focus mode is for. Press it and the digits fill the screen with nothing else on it. The numbers scale to the width of the display, so they are readable from the back of a room.
- Is anything I do here recorded?
- No. The timer runs entirely in your browser and nothing is sent to us. The only thing stored is whether you muted the beep, which stays on your own device.
- Can I send someone the same countdown?
- Copy share link puts the mode and the length into the address. Opening it sets up the same timer ready to start. It does not start it, so both of you can begin together.
- Can everyone watch one timer that I control?
- Yes. Share a live timer makes a page at /t/ followed by a six-letter code, and gives you a separate manage link with the controls. Everyone who opens the share link sees the same clock, and it starts, pauses and finishes for all of them the moment you press the button. It stays in step because the timer itself runs on our server's clock, not on any phone's: each page learns how far its own clock is from ours when it loads, then counts locally against that. Nothing is sent while it ticks, only when you press something, so it costs almost nothing and does not stutter on a bad connection. A live timer needs our server, so it is the one thing on this page that stops working if we are down; the timer above keeps going regardless.
