Shared by link, no account

A countdown
you can send.

Pick a length, get a link, paste it wherever people already are. Every browser that opens it lands on the same second.

Free for any number of people. Or run a timer just for yourself.

✦ The problem

Two timers are not one timer.

Sharing a timer is normally the awkward part: an app that wants accounts on both sides, or a screen share of somebody's phone. A link is the lowest common denominator. It pastes into a chat, a calendar invite, a slide, a message to one person, and it opens in whatever browser is already there.

✦ How it works

Three steps, no account.

1

Pick a length and press create

Give it a name if the room needs to know what the clock is for. Add a lead-in of a minute or two if people still have to open the link.

2

Send the link

It is copied for you. Paste it in the chat, the calendar invite, the slide, or open it on the screen at the front of the room. There is no room code and nothing for anyone to join.

3

Everyone finishes together

Every browser on the link reads the same countdown rather than keeping its own, so somebody who opens it late sees the time that is genuinely left. Pause it and the whole room stops; add five minutes and the whole room gets them.

✦ Where it earns its keep

What people share a timer for.

Two people, two places

A shared writing sprint, a study session, a workout done apart. Same clock, no call needed.

In a calendar invite

Put the link in the description. The countdown is waiting when the meeting opens.

In the chat thread

"Twenty minutes on this, then we decide." With a link, that sentence is enforceable.

On a second screen

Open it on a tablet next to you and the laptop stays clear.

✦ Plainly

One clock, not thirty copies.

The countdown is kept by the server, and every screen in the room is reading it rather than running its own. That is what makes the next three true at once.

A pause everybody sees

Pause, resume, add time or reset, and it lands on every screen within a couple of seconds. Not your copy of the timer, the timer.

A wrong clock cannot break it

Every reply carries the server’s own time, and each browser corrects for the gap. A laptop set four minutes fast still finishes with the room.

Only you can change it

The controls belong to the browser that created the timer, never to the link. Thirty people can hold the link and none of them can stop the lesson.

And still: nobody signs in, there is no room to join and no code to type, no limit on how many people open it, and the only thing stored is a length and whatever you called it — deleted a day after the countdown ends.

Other ways to use a shared clock.

Or a plain timer, just for you

✦ When the meeting ends

A shared clock is easy.
Shared work is the hard part.

The timer is free and always will be. What it cannot do is remember what the twenty minutes decided, or whose job the outcome became.

That is a shared workspace: goals, projects and tasks that belong to the group rather than to whoever created them, assignable to a person, with habits that keep a separate streak for everybody so nobody breaks anyone else’s. One subscription covers five people, and it is on your bill rather than theirs.

Questions

Shared timers, answered.

No. Creating the link, opening it and using it are all free and account-free. The only thing an EvyOS account changes is whether the session gets recorded against something you are tracking.
Yes, the link works for the whole life of the room. Someone joining halfway sees the time that is genuinely left rather than a fresh countdown, because they are reading the same clock as everybody else rather than starting their own.
Yes. Every reply from the server carries the server's own time, and each browser measures the gap between that and its own clock and counts against the corrected figure. A laptop set four minutes fast still finishes with the room. It is the one thing a countdown encoded purely in a link cannot fix, which is why this one has a server behind it.
Yes. When you create the link you can add a lead-in of a minute or a few, so people have time to open it before the countdown begins. Anyone who opens it early sees how long until it starts.
Yes, in any mobile browser. It also asks to keep the screen awake while it counts, where the browser allows that.

The clock is the easy half.
Keep the other half somewhere.

EvyOS holds the goals, projects, tasks and habits a shared workspace actually runs on. The timer stays free regardless.
