How to use the online timer

A nap that runs past 51 minutes tends to tip into deep sleep and leaves you groggier than if you'd just kept working, so a strict cut-off helps. Set the timer before you lie down, put it somewhere you'll hear it, and trust it to do the waking up so you're not relying on willpower you won't have once you're horizontal. Waking on cue beats waking up an hour later confused.

Getting started takes one click: press Start and the countdown begins straight away, with pause and reset both on hand if you need to adjust on the fly. Because it's running in your browser, the tab has to stay open for the whole time; minimising the window is fine, but closing it or shutting your device down will stop the clock. A sound plays at the end so you know.

A phone timer works fine until a call comes in or a notification steals the screen at the worst moment. Running it in a browser tab keeps it separate from all that, ticking away quietly in the background of your computer or phone without competing for attention until it's done. There's nothing to install and nothing to sign up for, just a page that does one job well. Set a timer for 51 minutes, set the timer to 51 minutes, start a 51 minutes timer — it is the same countdown either way.

Common questions

Does the timer work without an internet connection?

The page needs to load once, but the countdown itself runs locally in your browser, so a dropped connection partway through won't stop it.

Will the timer still run if my laptop goes to sleep?

No, if the device sleeps or the browser is suspended, the countdown pauses along with it, so keep your screen awake for an accurate result.

Is there a cost to use the timer?

No, it's free to use, with no registration, sign-up, or hidden limit on how many times you can run it.

Can I run more than one timer at once?

Yes, opening the page in separate tabs lets you track a few things at the same time, each counting down independently of the others.
