About

LUNG

Features
Read full description

LUNG KILLER is a slightly sarcastic smoking tracker that counts every cigarette and every bit of money you burn, with no excuses. It won't force you to quit and it won't lecture you. You tap a button each time you smoke. The app quietly keeps count of cigarettes and money, and now and then answers with a dry remark. Knowing how much you really smoke is the first step to cutting back. "Still clean today. Streak going." "3000 total. Curious about your lungs in 10 years?" "At this pace, you'll burn another $600 by the end of the year." TRACK - Log a cigarette with one tap. Tapped by mistake? Undo it - Today's count, lifetime total and money burned at a glance - Money is shown in your region's currency. Set your own pack price (20 cigarettes per pack) - A mini chart of the last 7 days - Time since your last cigarette, with a remark about the gap - Each day's count is saved to your history automatically at midnight HISTORY & INSIGHTS (new in 3.0) - Monthly calendar: heavier days are shaded darker, with the month's total - Daily averages for the last 7 and 30 days, plus your highest and lowest day in 30 days - Compared with the previous 7 days and with last month: up or down - Intervals between cigarettes: shortest, average and longest over the last 7 days (gaps over 12 hours, such as sleep, are excluded) - Yearly projection of count and cost if your current pace continues - Money burned, converted into bowls of ramen, movie tickets, game consoles and trips abroad SARCASTIC REMARKS - Messages that change with today's count and rotate a little each day - A remark at 100, 500, 1000, 3000, 5000 and 10000 cigarettes in total AI LUNG ILLUSTRATION (optional) - From your lifetime count, AI imagines and draws the current state of your lungs (5 stages) - Generated through our cloud server. Only a stage number from 0 to 4 is sent; never your actual counts, photos or name - An illustration for awareness only. It is not a medical diagnosis or a picture of your actual lungs - One illustration a day is free. Want another? Watch one short ad to the end and you get one more. If no ad is available at that moment, it is generated without one. Watching ads is entirely optional - Generation takes about 1-3 minutes, and there is a daily usage limit DAILY REMINDER (optional) - One notification a day at the time you choose, to look back at your log. Change the time or turn it off at any time 16 LANGUAGES Japanese, English, Chinese (Simplified and Traditional), Korean, Spanish, Portuguese (Brazil), German, French, Hindi, Indonesian, Russian, Italian, Turkish, Thai and Vietnamese PRIVACY - No account needed. Your counts, history and notification settings are stored only on your iPhone or iPad - The app uses no analytics tools of its own - To keep the app free, a Pangle banner ad is shown at the bottom of the counter and history screens, and an optional video ad unlocks extra AI lung illustrations (if no ad is available, they are generated without one). You choose whether to allow tracking in Apple's dialog on first launch. Every feature works either way - See the privacy policy for details This app does not encourage smoking. It helps you stop looking away from how much you smoke and how much you spend.
