Stop vaping. Watch your lungs heal.
The more you vape, the more your lungs rot. Puff Lung makes that real. Every puff drops your health. Every clean stretch starts bringing it back. It's not a streak counter or a calendar — it's a cartoon lung that visibly decays as you go over your goal, then heals when you commit to a detox.
If you're tired of "you can do this!" apps that ignore what your habit is actually costing you, Puff Lung is built different.
HOW IT WORKS
— Set your baseline. Tell us where you are now. No judgment.
— Pick your pace. Cut 1, 2, 3, or more puffs per day. Whatever you can keep.
— Tap every puff. Stay under your goal and your lungs stay healthy. Go over and they start to rot.
— Slip up? We adjust. Tomorrow's goal moves up to where you actually were, so it stays reachable. Then we keep working back down.
— Detox to heal. Run a 15m, 30m, 1h, 2h, or 4h detox. Stay clean and your lungs gain health. Vape during detox and every puff counts double.
FEATURES
• 20-stage cartoon lung that visibly rots and heals in real time
• Home screen widget — see your lung from your home screen at a glance
• Detox sessions with health rewards (up to +20 health for 4 hours clean)
• Adaptive daily goal that responds to your real usage instead of giving up on you
• Money calculator — see what your habit costs per week, per year, and over your lifetime
• What you could afford instead — based on your spending: a weekend in Cancun, 10 days in Japan, an African safari, 3 months backpacking Southeast Asia
• Full history with daily lung-stage tracking
• Trigger and reason mapping to keep your "why" in front of you
• 100% local data — your puff log never leaves your phone

WHO IT'S FOR
People who already know vaping is bad for them and want to actually do something about it. Built for the kind of person who can take a hit of reality alongside a hit of accountability. If your last quit attempt got eaten by another disposable, this is the tool that doesn't let you forget what's happening to your lungs.
