Smoke Detox is a behavior-support mobile app created to help individuals quit smoking through structured motivation, habit tracking, and wellness-oriented tools. The app does not provide medical services, track vital signs, or connect to any health hardware. Instead, it offers educational content and guidance based on widely recognized public health research on smoking cessation. We believe quitting smoking is a personal journey, and our app is designed to make that process more manageable and motivating. From daily milestone tracking to habit reinforcement modules, Smoke Detox provides tools to help users stay committed, informed, and encouraged.

Habit Tracker: Record cigarettes smoked daily, monitor patterns, and track your progress in real time. Sound & Video Content: Access calming audio and motivational videos designed to reduce stress and support your goals. Motivational Insights: Get encouraging reminders, facts, and tips to stay focused and positive. File Locker: Upload personal lung test reports or progress photos—securely stored for your reference. Goal-Based Milestones: Unlock encouragement badges and journaling prompts as you move through your quit journey. All features are designed with privacy in mind. The app does not collect sensitive health data, and users can request account deletion at any time via My Profile > Request Account Deletion. How It Helps You Quit Smoking Smoke Detox supports you with a gradual, pressure-free quitting method built around psychology and habit change—not willpower alone.
