Quit smoking with a score you can actually see improve.
Lung Score turns your smoking history into a personal Lung Score, a Risk Score, and a day-by-day recovery timeline — plus a real community of people quitting alongside you.
Lung Score's estimates are generated from information you provide and public research. They are not a medical diagnosis and are not clinically validated — always talk to a doctor about quitting smoking.
Everything you need to make quitting stick.
Lung Score & Risk Score
A personalized score built from your smoking history, symptoms, and lifestyle, with a day-by-day recovery projection as you stay smoke-free.
Progress tracking
Watch your smoke-free streak, money saved, and health timeline update in real time — every day without a cigarette counts visibly.
Craving tools
In-the-moment breathing exercises and craving trackers designed to get you through the next 5 minutes, which is usually all it takes.
Sleep & habits
Track how quitting affects your sleep and daily habits, so you can see the wins that don't show up on a calendar.
Community
Post progress, questions, advice, or motivation, and cheer other people on — moderated with reporting and blocking built in.
Achievements & Walk of Fame
Unlock milestones as you go, and see the longest smoke-free streaks in the community on the Walk of Fame leaderboard.
Built to feel like progress, every single day.
A community of people quitting, right alongside you.
Share milestones, ask questions, and get encouragement from people on the same path — post as progress, a question, advice, a milestone, or pure motivation. Every post has a Report and Block control, and anything that collects multiple reports is automatically hidden pending review.
