Optimized user experience.
Quit smoking with a clear next step for every day — and every craving.
Defog is a neuroscience-informed 61-day quit-smoking plan built around practical behavior-change tools. Each day gives you one focused session with calming sound, a short lesson, an interactive exercise, and a simple check-in, so you can work on the habit without trying to solve everything at once.
WHEN A CRAVING HITS
Open Craving SOS for a guided reset. Use paced breathing and frequency-based sound as steady anchors while the urge rises and falls, then log what triggered it and what helped. Defog's toolbox adds 20 quick options, including urge surfing, grounding, body scans, thought reframing, journaling, and simple distraction games.
A 61-DAY PATH TO NEW ROUTINES
Move through eight stages — from understanding nicotine withdrawal and mapping triggers to rewiring routines, building resilience, and creating life after cigarettes. Daily lessons turn neuroscience and behavior-change ideas into practical actions. One new day unlocks each calendar day, and a slip never erases your program progress.
SEE YOUR RECOVERY ADD UP
Follow your smoke-free time, money saved, best streak, cigarette trend, cravings ridden out, body-recovery milestones, and progress across the full 61-day journey.
