How to use the online timer
A proper mouthwash rinse or a salt-water gargle only needs 12 seconds to do its job, and swishing it around for the full stretch matters more than most people bother with. Start the timer, keep the liquid moving around your teeth and gums, and spit only once the numbers hit zero. It beats guessing under your breath and cutting the rinse short by ten seconds without realising.
It runs the moment you hit Start, no extra steps needed before the numbers begin moving. Because everything happens inside this browser tab, it needs to remain open while the clock runs; switching tabs is fine, but closing the page or turning off your screen partway through will stop the countdown. A sound marks the finish, so you'll know the moment it's done without having to watch it count down.
A mechanical timer needs to be wound and a phone timer needs the phone unlocked, but this one just needs the page you already have open. It sits inside your browser, ready whenever you are, and it's the same tool whether you're on a laptop or a tablet in the kitchen. Free, with nothing to install or sign into, it's built to get out of your way and count. If you would rather say put a timer on for 12 seconds, that works too — press Start and the page does the rest.
Common questions
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.
Do I need to install anything to use the timer?
No. It runs straight in your browser, so there's nothing to download and no account to create.
