ClearLung
Quit smoking for good — without giving up your privacy
ClearLung combines 15 CBT therapy lessons, 10 guided mindfulness exercises, and an SOS craving button into one quit-smoking toolkit. Every craving, slip, and milestone stays on your device — no account, no ads, no tracking.
Willpower alone isn't a plan. A method is.
Quitting smoking is one of the hardest things you'll ever do — and most apps respond by selling your data or bombarding you with ads. ClearLung takes a different path: a compassionate, science-based toolkit built on smoking cessation research.
The problem with going it alone
- Cravings hit hardest at specific times and triggers — and without a system, every urge becomes a coin flip.
- One slip often spirals into full relapse when it's treated as total failure instead of information.
- Many quit apps demand accounts, upload your health data, and interrupt vulnerable moments with ads.
How ClearLung answers it
- CBT lessons teach you to identify triggers, challenge automatic thoughts, and build lasting coping strategies.
- Non-judgmental slip tracking treats every setback as valuable data — research shows self-criticism after slips increases relapse rates.
- Zero network permissions: your journey lives in a local database on your device, and nowhere else.
