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.

CalliShape builds your calisthenics program around your body, not an average one. Two minutes of questions — goal, age, height, weight, build, available equipment, sensitive joints — and the app lays out your week. From then on, every set you log tunes the next one: too easy and the difficulty goes up, too hard and it comes back down. Nothing to configure. WHAT YOU GET • A plan that recalculates after every set • 154 animated exercises, from wall push-ups to the human flag, with technique cues and common mistakes • 10 skill trees: muscle-up, handstand, front lever, planche, L-sit, pistol squat, back lever, human flag, one-arm push-up and one-arm pull-up • 16 guided programs: my first pull-up, road to 100 push-ups, handstand in 8 weeks, gentle restart, active after 50, everyday mobility and more • Custom workouts you build yourself, with the same progression applied DURING THE WORKOUT • Giant counter, one-tap logging, rest timer with fifteen-second adjustments • Voice coach for sets, rest and side switches • Lock screen and Dynamic Island: the timer keeps running and the buttons respond without unlocking • An easier or harder variation one tap away, at any moment ON APPLE WATCH Your workout travels to your wrist and runs without your iPhone. Heart rate, calories, Activity rings, haptics at the end of each rest. The result returns to your iPhone, which applies the progression. YOUR PROGRESS, MEASURED CalliScore and ranks, a six-axis strength radar, curves per movement family, weekly volume, personal records, twelve weeks of consistency, weight, measurements and before/after photos. 44 trophies and challenges calibrated on your last four weeks, not on generic targets. YOUR BODY, YOUR LIMITS Wrists, shoulders, elbows, back, knees, hips, blood pressure, pregnancy, postpartum, osteoporosis: risky movements are replaced with safe variations, and both warm-up and recovery grow with age. YOUR DATA STAYS WITH YOU No account, no server, no ads, no tracking. Everything is stored on your iPhone. Backup and CSV export whenever you want. Health app sync only if you allow it. Available in English, French, Spanish, German and Portuguese. CalliShape offers general training programs and is not a substitute for medical advice. Stop if you feel pain.
