According to LifeSign, the manufacturer of the QuitKey, the program has been proven effective with grants from the US National Institute of Health. The computer is small, about the size of a stopwatch, and can be used as a key chain.  This makes it discreet and not as bulky as some other smoking step-down devices.

The QuitKey  reminds you when to smoke and when not to smoke, step-by-step, hour-by-hour, one day at a time. Designed to work in two stages, QuitKey will create a personalized quit plan based on your regular smoking routine.

The first stage lasts seven days. During this stage you smoke at your normal rate and use the QuitKey smoke button to record every cigarette you smoke. QuitKey compiles this data and uses the information to built a personalized quit plan.

Stage two follows immediately and can last from 14 to 34 days, depending on the data compiled during Stage 1. During Stage 2, QuitKey helps you follow your quit plan by prompting you when to smoke. Each day you will smoke less and gradually reduce your nicotine dependence. With this gradual, step-down method you’re preparing yourself to quit cigarettes for good, drug-free and without chemical-induced side effects.

The QuitKey comes with a complete quit smoking program guide.
