Smoke Detox is a behavior-support mobile app created to help individuals quit smoking through structured motivation, habit tracking, and wellness-oriented tools.

From daily milestone tracking to habit reinforcement modules, Smoke Detox provides tools to help users stay committed, informed, and encouraged.
