Shareable Timer

About

A free online timer that runs countdowns back to back. Name a step, give it a length, and when it reaches zero the next one starts on its own — a two-note chime at every hand-over, a three-note flourish at the finish. A sequence takes up to fifty steps, each from one second to twenty-four hours, typed the way people say them: 25, 25m, 1h30m, 90s, 1:30. Ten presets ship as ordinary sequences you can edit — Pomodoro 25/5, 52/17 deep work, HIIT, Tabata, box breathing, boiled eggs, meditation, a talk with Q&A, kids' screen time, a power nap — and the segment rail under the digits draws every step at a width proportional to its length, so the shape of a session is visible before it starts.

The link is the timer. The steps, their names, the moment Start was pressed, the time zone and your finish message all live in the address bar, so there is no account to make and no backend of ours behind it. Press Start and the link records that instant; whoever opens it afterwards works out how much has elapsed and lands on the identical second — a colleague across the building, a room of people on their own phones, the same person on a second device. Pausing stores the elapsed time instead, so a paused link stays paused for everyone holding it, and skipping a step shifts the recorded start so every reload still agrees.

Type a clock time as the first step — 6:30am, @18:45, noon — and the sequence becomes a standing schedule instead. There is no start button: open the link on any day and it is already counting down to the next 6:30 AM, runs whatever steps follow, and repeats at every 6:30 AM for as long as the link exists. The zone those clock times are read in is pinned into the link as an IANA name, so 6:30 AM in Kolkata is still 6:30 AM in Kolkata when the link is opened in New York, while a viewer can switch the times on their own screen to their own zone without changing anything for anybody else. Every wall-clock time the page prints carries its abbreviation — 11:47 PM IST — rather than a bare reading.

It is built to be looked at from across a room. The digits size themselves to the window, a screen wake lock keeps a phone or a laptop awake while a sequence runs, and a focus view or real fullscreen strips the page down to the step name, the countdown and the steps with their end times — for a phone propped on a desk, a television, or a projector at the front of a class. Space, S, R, E, Z, F and M drive it from the keyboard, the chime is synthesised in the browser rather than fetched, up to forty characters of your own replace the word DONE at the finish for everyone on the link, and the last seven timers this browser used sit above the presets. It is free, and there is nothing to install. One caveat stated plainly: all the timer keeps is local — your sound choice, your zone and your last seven timers, in this browser — but the timer page carries the same analytics and ad script as the rest of the site, and what analytics records is the address, which there is the timer itself.

Who it’s for

Anyone timing something with more than one part — a Pomodoro block, an interval set, a talk with Q&A, a lesson, a boiled egg — and anyone who needs a whole room watching the same clock: send the link and every screen counts down together. The schedule form fits whatever happens at the same time each day, where the link simply has to be right whenever somebody opens it.
