Two of the most effective things in a quit app are also the least impressive-looking: a number that counts up, and a button you press when you want to vape.
Why streaks work
A streak converts an abstract goal into a possession. Behavioural economics is consistent on this point: people work harder to avoid losing something they have than to gain something equivalent they do not.
"Be a non-vaper" is abstract. "Do not lose 17 days" is concrete, and it is available at the exact moment you are deciding.
The effect is strongest in weeks one to four, which is where the relapse risk sits.
Why streaks can backfire
If one puff sets the number to zero, the tool has just made a small event catastrophic. That is the abstinence violation effect: the slip is minor, the interpretation of the slip is what ends the quit attempt.
A better design records the slip on the timeline without erasing the run. The honest log is worth more than a clean-looking number.
Practical rule: if your tool punishes honesty, stop using that part of it.
Why craving logs work
Self-monitoring, simply recording a behaviour or urge, reliably changes it. Two mechanisms:
- Attention. Logging inserts a two-second gap between urge and action. Some cravings die inside that gap.
- Pattern. Cravings feel random from the inside. They almost never are.
What to log
Keep it to three fields, five seconds maximum:
- Time (automatic)
- Place, car, desk, kitchen, bar
- Mood, one word: stressed, bored, tired, happy
Optional fourth: intensity, 1–5.
That is it. Every extra field lowers the chance you log at all, and an unlogged craving is worth nothing.
Reading your own data
After about seven days, look for:
- A dominant hour. Most people have one, often mid-afternoon or the first hour after work.
- A dominant place. Usually a transition space, car, doorway, balcony.
- A dominant mood. Stress and boredom split most of the field.
Then build one specific plan per pattern. "3pm, at my desk, bored → stairs and water" beats "resist cravings better" by a wide margin.
The 30-day view
By day 30, the log becomes evidence: cravings that arrived hourly now arrive a few times a week, and the peaks are lower. That graph is the strongest anti-relapse argument you will have, because it is about you rather than about statistics.
