Quit vaping or smoking
Lungful helps you quit vaping or smoking, and actually stay quit. Most quit apps guilt you when you slip. Lungful doesn't. It tracks your progress honestly, gives you real coping tools, and celebrates every hour you stay free.
Free on iPhone and Android. The craving SOS button is free forever.
01, Your daily heartbeat
Open Lungful and your live counter is right there, every second you've stayed free, counting up. No fake numbers, no quiet resets. Money saved and nicotine avoided update in real time, and your next health milestone is always one glance away.
02, When a craving hits
Cravings peak and pass in minutes. Hit Craving SOS and Lungful walks you through it, paced breathing, urge-surfing, and your own reasons for quitting. No guilt, no lecture. Just a calm hand to get you to the other side.
03, The companion that knows you
Your companion learns your triggers, remembers what you told it last week, asks how the party went, and checks in before your hardest hour. Not a chatbot with amnesia, a relationship that grows like the tree on your home screen.
04, Your body, healing
From the first 20 minutes to a full year, Lungful maps the real recovery happening inside you, every milestone sourced from the CDC. See exactly what's already healed, and what's coming next.
05, Tools that actually help
Breathing exercises and grounding drills, free and always one tap away, plus CBT thought records from professional quit programs in Premium. No forums, no ads, no judgment.

Built to help you quit, not to harvest you.
DAY 1
And after a slip it never shrinks. It waits for you.
Why Lungful is different
Other apps lean on guilt, ads, and noisy forums. Lungful was designed the opposite way from day one.
You are quitting nicotine, not getting sold to. Lungful never shows an advert, anywhere, full stop.
The craving SOS toolkit is never locked behind a paywall. When a craving hits, help is one tap away at no cost.
Recovery figures are accurate and cited, sourced from the CDC, not invented to make you feel good.
No feed to doomscroll and no strangers to compare yourself against. Your journey stays private.
Built for vapes and cigarettes from the start. Whatever you use, Lungful speaks your language.
Download free, start your streak, and keep the tools that matter most without paying a cent.
Everything you need
A streak you can watch tick upward, science-backed coping techniques, and proof your body is healing.
Your nicotine-free time counts up to the second. And if you slip, only the clock resets. Your lifetime total, money saved, and longest streak all survive.
One tap away, always. Breathe with guided 4-7-8 and triangle patterns, ride the urge out like a wave, or distract with quick mental tasks.
See what's happening in your body, hour by hour. Carbon monoxide clears, lung function climbs, heart-attack risk drops. Sourced from the CDC.
Your live money-saved total is free, always on your dashboard. Premium adds daily and weekly charts that show exactly what you've kept.
From First Step at 20 minutes to One Year. Each badge fires a full-screen celebration the moment you earn it.
Not ready to quit cold turkey? Set a daily limit and Lungful steps it down week by week, then you graduate into a full quit with all your progress banked.
Name the craving thought, spot the distortion, write a balanced response. The same technique used in professional cessation programs.
An optional companion to talk through a hard moment; your first 10 conversations are included free. It is the one feature that talks to a server: messages pass through our stateless relay to generate the reply and are never stored there. Your transcripts live only on your phone.
Your body, healing
From your last puff onward, your body begins repairing itself. Every figure below is sourced from the CDC.
Source: U.S. Centers for Disease Control and Prevention (CDC). Individual recovery varies.
Your data lives on your device, not our servers. The only feature that ever uses a server is the optional AI Companion Chat, and even then our relay stores nothing. Your quit journey is yours alone.
Questions, answered straight
Yes. The streak counter, the craving SOS button, breathing exercises, craving insights, the health recovery timeline, and your live savings total are all free, and the SOS button stays free forever. Premium adds savings and craving charts, 19 milestone badges, guided sessions, the CBT thought record, and unlimited companion chat.
Both, from day one. Lungful adapts its language, savings math, and milestones to whether you vape or smoke. No cigarette-only copy pasted at vapers.
The clock restarts. That's it. Your lifetime nicotine-free total, money saved, longest streak, and badges all survive. A slip is information, not failure, and the app treats it that way: no guilt screens, ever.
Your data lives on your device. No account, no ads, no trackers. The only feature that touches a server is the optional companion chat, and that relay stores nothing. You can export or permanently delete everything from Settings at any time.
No. It's a self-help support tool, not medical care. Quitting works best when tools like this are combined with human support: for free coaching call 1-800-QUIT-NOW, and if you're in crisis call or text 988 (US, free, 24/7).
Lungful is out now, free, on the App Store for iPhone and on Google Play for Android.
Download Lungful, start your streak, and keep the panic button free for life.
