Set the timer to 43 minutes

How to use the online timer

A focused work block of 43 minutes is a solid length for chipping away at a task without your attention drifting off after the first ten minutes. Start the timer, close whatever tabs are tempting you, and treat the deadline as real even though you set it yourself. When the alarm goes, you've either finished the job or made a proper dent in it, which beats an open-ended hour of half-attention.

There's no setup beyond pressing Start, and the countdown handles the rest on its own from that point. Since it runs inside the browser, keep the tab open for the timer to keep an accurate count; you can switch to other tabs in the meantime, but closing this one out resets things. When the countdown hits zero, a sound plays so you're not stuck staring at the numbers.

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. If you would rather say put a timer on for 43 minutes, that works too — press Start and the page does the rest.
