【Core Philosophy】 Every time you light up, you are overdrawing your future. "Quit?" is not just a tracking tool; it is a mirror reflecting the real damage your body is enduring. We refuse to preach. Instead, we use high-impact 3D Visualization and a Life Countdown to help you regain your respect for your health.

【Key Features】

3D Lung Evolution Engine：
Say goodbye to boring numbers. Every cigarette you log is instantly reflected on the 3D lung model in the main interface.
Watch it transform from a pristine, glowing state to becoming sooty, charred, and withered. This direct visual stimulation is more effective than any warning label.

Life Countdown System：
Based on epidemiological statistics, we visualize "Smoking Kills" into a precise "Life Deduction."
Watching your remaining time slip away second by second, you will realize: You aren't just smoking away boredom; you are burning through your limited time.

Exercise "Redemption" Protocol：
If you make a mistake, make up for it. Deep integration with Apple Health (HealthKit).
Use running or walking to offset the simulated damage values caused by smoking. Let the dopamine from exercise replace the craving for nicotine.

Privacy First, Local Storage：
We know that smoking records are extremely private.
No Servers. No Uploads. All your data is stored locally on your device. No one knows how much you smoke but you.

【Disclaimer】 The "Life Countdown" and lung model changes in this app are visual simulations and artistic expressions based on general statistical data. They are for smoking cessation motivation only and do not represent actual medical diagnoses or specific life expectancy predictions.
