1 hour timer
No sign-up. No ads.

One hour, counted properly, with an alarm at the end.

60 minutes remaining of 1 hour

Keeps time in a background tab. Works on a phone. Share one countdown with a room if more than one person needs it.

1 hour

Why sixty minutes.

An hour is the unit everything else is measured against, and the one people are worst at feeling. An hour of focused work and an hour of drifting look identical from the inside; only the clock can tell them apart.

✦ What it is for

What people set a 1 hour timer for.

A deep work hour

One hour, one thing, nothing else open. The most valuable hour in most days.

Slow cooking

Braises, roasts and bread all live on the hour mark.

A capped meeting

An hour that everyone can see ending tends to be an hour.

Screen and gaming limits

Set before it starts, not argued about after.

✦ How to

How to set a 1 hour timer.

1

Open this page

It is already set to sixty minutes, so there is nothing to type and nothing to choose. The timer is the first thing on the page.

2

Press start

The countdown begins immediately and the ring starts emptying. The tab title counts down too, so you can watch it from another tab.

3

Leave it running

Switch tabs, lock the phone, let the laptop sleep. It is counting to a fixed end time, not adding up ticks, so it stays correct.

4

Get the alarm at zero

A chime repeats until you stop it, and a browser notification arrives if you allowed one. Reset restarts the 1 hour timer, or switch to another length in one click.

✦ The timer itself

Built to be trusted, not just to tick.

Most free timers are an interval and a beep. Under a background tab, an interval is the first thing a browser throttles.

Accurate in a background tab

It counts to a real end time rather than adding up ticks, so a hidden tab, a locked phone or a sleeping laptop cannot make it drift. Come back and it already shows the right number.

A visual countdown

The ring empties as the time goes, which reads from across a room and suits anyone who does not carry an accurate sense of elapsed time. Full screen turns it into a wall clock.

An alarm that repeats

A chime at zero, repeated rather than sounded once, plus a browser notification if you allow one. Mute is a single click, and the tab title counts down either way.

No account, no ads, no tracking wall

Nothing here is gated. There is no interstitial before the timer starts and no video playing next to it.

Keeps the screen awake

While it runs it asks the browser not to dim the display, so a phone propped on a counter still shows the time left.

Adjustable mid-run

Add a minute or five without restarting, pause and resume where you left off, or switch to another length in one click.

✦ Other lengths

Need a different timer?

✦ More than one person

Timing a room, not just yourself?

Create a countdown, send the link, and every browser that opens it ends on the same second — with a pause that stops the whole room. Still no account, still nothing to install.

✦ After the alarm

A timer tells you when to stop.
It cannot tell you what it was for.

This page will still be here tomorrow, free, and for a lot of people that is the whole relationship. But a countdown is only the last five minutes of a decision that started somewhere else, and the useful question is not how long you sat down for. It is whether the sitting down added up to anything.

EvyOS is where that part lives. The same timer, attached to a real task, a habit you are keeping or a skill you are logging hours against, so a 1 hour session becomes a record instead of a moment. Goals hold projects, projects hold tasks, and the practice you put in is counted rather than remembered.

Questions

1 hour timer, answered.

Yes. It is anchored to a real end time, so a sleeping laptop or a locked phone does not slow it down. Come back and it shows the correct remaining time, or the finish if it has passed.
Yes. Add a minute or five while it runs, or restart from the finished screen.
No, the timer is free and needs no sign-in.

The 1 hour is the easy part.
Keeping the habit is not.

EvyOS holds the goals, projects, tasks, habits and skills the timer is in service of, and counts the sessions you actually did.
