Quitting is a skill, and skills can be trained.

1. QQuestionDay 0 and days 4 to 7

   Question the thought that says "just one"

   Every habit comes with a script: it is only flavor, I deserve this, I can stop whenever I want. The first pillar makes the script visible. You write down your reason for quitting, look at the thoughts that pull you back and test them against what you actually know. It draws on cognitive behavioral therapy and on motivational interviewing, where change grows out of your own reasons instead of someone else's lecture.^{1, 2, 3, 5}

   In the app. A daily reflection question, your reason saved from day 0 and short lessons that take apart the most common excuses.

2. UUrgeDays 1 to 3 and 8 to 11

   Ride the urge instead of obeying it

   A craving feels like an order, but it behaves like a wave: it rises, peaks and falls, usually within minutes, even if you do nothing. Urge surfing trains you to notice it, rate it, breathe and let it pass. Add if-then plans ("if the urge shows up after dinner, then I brush my teeth and go for a walk") and your hardest moments get a script you wrote in advance, when you were calm.^{6, 7, 8}

   In the app. The SOS button, always free: a guided script of breathing and observation with a timer. A map of your triggers and if-then plans for each one.

3. IIdentityDays 12 to 19

   Become someone who does not need it

   Quitting sticks better when it is not only something you avoid but someone you are. In a well-known field study, people whose goal was framed as an identity ("be a voter") turned out to vote more than people whose goal was framed as an action ("vote"). This pillar applies the same logic day by day: what you say to others, how you handle parties, stress and boredom, what you do with the time the habit used to take.¹¹

   In the app. Lessons and prompts written around who you are becoming, plus practice for the situations that used to be automatic.

4. TTrackDays 20 to 30

   Keep score, and expect a slip

   Progress you can see keeps you going, so this pillar turns days, money and time back into numbers. It also prepares you for the slip, because most people who change a habit slip at least once. Relapse prevention separates a lapse from a relapse: one slip is information, not a verdict. Treating it as total failure is what turns a lapse into a return to the old habit.^{9, 10, 12}

   In the app. Counters for days, money and time back, health milestones and a plan for the 24 hours after a slip.

1. Day 0

   QQuestion: Choose the date and your reason

   You set the day of your last one and keep the tools out of reach. No drama, no big promise.

2. Days 1 to 3

   UUrge: The first storm

   Body and mind push back hardest at the start. You meet the SOS, learn urge surfing and time your first cravings.

3. Days 4 to 7

   QQuestion: Question the excuses

   Just this once, I deserve it, I can stop whenever I want. You take the stories apart, one at a time.

4. Days 8 to 11

   UUrge: Map your triggers

   You find when and where the urge shows up and write an if-then plan for each situation.

5. Days 12 to 19

   IIdentity: Who you are now

   Parties, stress, boredom, weekends. You practice the situations that used to be automatic and tell someone what you are doing.

6. Days 20 to 30

   TTrack: Slips, plan and gains

   You learn what to do after a slip, write your anti-relapse plan and see what you got back. Day 30 is a checkpoint, not the end.

Thirty days is where the plan ends, not where the change becomes permanent. In one study of new daily habits, feeling automatic took 66 days at the median, with a wide range. The apps stay useful long after day 30.¹²

• Cognitive behavioral therapy

  Aaron T. Beck and others

  A structured approach that links thoughts, feelings and behavior and trains you to change the thoughts and habits that keep a problem going. A review of the meta-analyses supports it across many problems, and a meta-analysis of randomized trials with adult alcohol and drug users found a small but significant benefit.^{1, 2}

  How iQuit uses it. Reflection questions, lessons that take apart excuses and the habit of noticing the thought before the action.

• Motivational interviewing

  William R. Miller and Stephen Rollnick

  A collaborative style that helps people find their own reasons to change and resolve mixed feelings, instead of being told what to do. Meta-analyses of controlled trials show it helps people reduce substance use compared with no treatment, with modest average effects.^{3, 4, 5}

  How iQuit uses it. Your reason comes first, in your own words, and every lesson is non-judgmental. No scare tactics, no shame.

• Relapse prevention

  G. Alan Marlatt and Judith Gordon

  A model that teaches you to spot high-risk situations, cope with them and treat a slip as a lapse to learn from, not a total failure. Reviews of controlled trials support it for addictive behaviors.^{9, 10}

  How iQuit uses it. The trigger map, the plan for the 24 hours after a slip and the anti-relapse plan in the last stretch.

• Urge surfing

  G. Alan Marlatt, tested by Sarah Bowen

  Cravings are observed, not fought: you notice the sensation, breathe and watch it rise and fall. In a study of 123 college smokers, a brief urge-surfing instruction reduced smoking over the following week compared with a control group, even though reported cravings did not shrink. It was a small, short study.⁶

  How iQuit uses it. The SOS: a guided script of breathing and observation, with a timer, that you can open in the middle of a craving.

• Implementation intentions

  Peter M. Gollwitzer

  If-then plans that link a situation to a response: "if X happens, then I will do Y". A meta-analysis found a medium-to-large effect on reaching goals. Most of that evidence is about goals in general, not about quitting in particular.^{7, 8}

  How iQuit uses it. Ready-made if-then plans for the situations you pick from your trigger map.

• Identity-based motivation

  Christopher J. Bryan and colleagues

  Describing a goal as who you are ("be a voter") rather than what you do ("vote") led to more real-world follow-through in field studies. The evidence for quitting habits specifically is thinner, so iQuit uses it as a way of framing, not as a guarantee.¹¹

  How iQuit uses it. Lessons and prompts in the Identity stage, written around "someone who" instead of "do not".

• How long habits take

  Phillippa Lally and colleagues

  In a study of 96 people building a new daily habit, reaching a plateau of automaticity took from 18 to 254 days, with a median of 66. Missing a single day did not derail the process. The study looked at new habits, not at quitting.¹²

  How iQuit uses it. Why the plan expects slips, and why 30 days is a start and not a finish.
