2 Minute Timer
Two minutes is the number your dentist keeps repeating. It is also roughly three times longer than most people actually brush, which is the entire argument for putting a clock on it.
What a 2 minute timer is good for
Dental associations settled on two minutes of brushing twice a day, and study after study finds that people who believe they brush for two minutes are usually managing about forty-five seconds. Running a visible timer closes that gap immediately, which is why so many parents prop a phone on the bathroom shelf.
The kitchen uses the same two minutes. A soft-boiled egg with a runny yolk, a French press given long enough to bloom before you push the plunger, a sauce that needs a short hard boil rather than a simmer. These are the jobs where thirty seconds either way is the difference between right and ruined.
It is also a useful length for a transition. Two minutes of warning before a screen goes off, or before a small child has to put shoes on, converts an argument into a countdown everyone can see. Adults use the same trick on themselves with a two-minute plank.
How to use this timer
The countdown above is already set to 2 minutes. Press play to start it, or use the boxes to change the length if you want something else. The alarm keeps ringing until you stop it, so it still reaches you from another tab or another room.
Reset returns the clock to 2 minutes rather than to zero, which is what you want when you are running the same block more than once.
The two minute rule, and why a timer makes it work
The two minute rule says that if a task takes less than two minutes, you do it now instead of writing it down, filing it or thinking about it again later. The reasoning is that the overhead of tracking a small job usually costs more than the job itself.
The rule collapses in practice because almost nothing feels like it will take two minutes. Answering that email, rinsing that pan, filing that receipt: each one expands in the imagination until it looks like a project. Starting a two minute timer calls the bluff. Most of those tasks finish with time to spare, and the ones that genuinely overrun are worth knowing about, because those are the ones that belonged on the list after all.
Frequently asked questions
How long should I actually brush my teeth?
Two minutes, twice a day, is the standard advice from dental associations. The usual suggestion is to split it into four thirty-second quadrants so no part of the mouth gets rushed. Most people significantly overestimate how long they have been brushing, which is exactly why a visible timer changes the outcome.
Can I set the timer to repeat for each quadrant?
There is no quadrant chime, but a common approach is to watch the digits and move on at each thirty-second mark, since the countdown is large enough to read from across the bathroom. If you want an audible split instead, run four thirty second timers back to back.
Does the timer work offline?
Yes. After the first visit your browser has the page cached, so it opens with the network off and the countdown runs entirely on your device. Nothing is sent to a server, which also means a patchy bathroom wifi signal has no effect on it.
Can I mute the alarm and use vibration instead?
The timer plays whichever alarm sound you have chosen in settings, and muting the tab silences it. Vibration is not something a web page can trigger reliably across phones, so if you need a silent finish the practical route is to mute the tab and watch the digits reach zero.
