Marlboros aren't menthols. Roll-your-own isn't a pack-a-day. ClariLung accounts for your cigarette type.
Full flavor filtered — the classic. High chemical load, well-studied recovery curve.
Low-tar, filtered. Often smoked more deeply — not actually less harmful.
The menthol numbs the throat irritation, making it easier to inhale more, more often.
Hand-rolled tobacco. Users often underestimate intake — tracking matters.
The chemical and psychological hooks in cigarettes are uniquely powerful. Knowing them helps.
A cigarette delivers over 7,000 chemicals with each smoke, including ~70 known carcinogens. The body normalizes to these quickly and protests when they stop.
The smoke break is woven into work schedules, social life, after-meals, and morning coffee. The habit isn't just chemical — it's structural.
Physical nicotine withdrawal peaks around 72 hours. The third day is the hardest — knowing that helps you prepare rather than surrender.
Other smokers, certain venues, specific emotions — decades of conditioning mean cues can trigger urges years after quitting.
Recovery typically begins within the first 20 minutes. These milestones are specific to cigarette smokers — sourced from CDC, NHS, and American Lung Association cessation research.

Every screen names what you actually use. Your streak, your stats and your taper all read in cigarettes, not in someone else’s units.



Actual app screens · sample data
Smoking affects resting heart rate, blood oxygen, and the aerobic capacity VO₂ max measures. Most quit apps show everyone the same generic recovery timeline. In the ClariLung mobile app, these come from your own Apple Watch or Android wearable and are charted against your pre-quit baseline.
Requires the iOS or Android app and a device that records these metrics. ClariLung reads what your wearable already collects — it displays trends, and does not diagnose or predict any health outcome.
Six tools built around how cigarette addiction actually works.
Log each cigarette. Watch daily count drop. Know your worst trigger windows — coffee at 8am, stress at 3pm.
The hardest part is day three. The AI Coach knows this and is ready — with your history, your patterns, and strategies that worked before.
Reduce cigarettes per day along a quadratic curve. Less shock to the system, better long-term adherence than cold turkey alone.
From 20 minutes (heart rate and blood pressure typically begin easing) to 5 years (stroke risk approaching a non-smoker's, per public-health data). Real data for cigarette smokers specifically.
Cravings last 3–5 minutes. Breathe through it with a guided exercise, or tap to log it and watch it pass.
A pack-a-day habit at $10/pack is $3,650 a year. ClariLung shows your savings in real time, day by day.
