How the timer works
Three hundred seconds, counted down. The ring is a circle with a 478-unit dash and its offset is the fraction of the five minutes still to run, so the gap in the ring is the time left. The colour walks from the site's orange to green across the countdown by moving each of the three channels a proportional step, which is why it is a gradual change rather than a switch at the end.
The breathing pane runs the 4-7-8 pattern: four counts in, seven held, eight out, looping until you stop it or the clock does. That pattern was popularised by Dr Andrew Weil and has roots in pranayama practice; it is a technique, not a treatment, and this page does not claim it does anything to nicotine.
Now the number the page is named after, said carefully. Five minutes is the length of the commitment, not a measurement of a craving. The NHS's own page says cravings last up to fifteen minutes. Five was chosen because it is a stretch of time a person will actually agree to sit through when they very much do not want to, and because the useful move during a craving is to put something between the urge and the hand rather than to wait out a precise duration. If yours is still going at five minutes, start it again — that is a normal outcome and not a sign the method is wrong.
The craving count is tallied per day in this browser. It exists so you can see the count going down over a week, which is the only thing about a craving that a page like this can honestly show you.

Nothing on this page is medically reviewed and nothing above measures anything about you — it
explains a calculation. Where a number here is our own judgement rather than a published figure, the
note says so and cites nothing; where the health bodies disagree, it carries the disagreement.
