Set the timer to 34 minutes

How to use the online timer

A nap that runs past 34 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 browser timer beats digging out the one kitchen timer that's always gone missing, and it's one less thing cluttering your phone alongside a dozen apps you barely open. Everything runs here in the tab, so there's no download, no account, and no permissions to grant before you can start it. Free, with no registration, it's ready the moment you load the page and gone the moment you close it. Set a timer for 34 minutes, set the timer to 34 minutes, start a 34 minutes timer — it is the same countdown either way.
