Store description excerpt
A quit-smoking companion app where an angel and a devil banter on your shoulders. We aimed for a design that's fun to keep going — never preachy, never punishing. ■ Key features ▼ See your progress, second by second A live counter shows your total smoke-free time and your current clean streak, down to the second. Money saved and cigarettes avoided update in real time based on your brand and price. ▼ 8-stage health recovery timeline A timeline grounded in publicly available information from WHO, the U.S. Surgeon General Report, the CDC, the UK NHS, and Japan's MHLW e-Healthnet: ・20 minutes — heart rate and blood pressure start to drop ・8 hours — carbon monoxide level halves ・24 hours — heart-attack risk begins to fall ・2–3 days — taste and smell return ・2–12 weeks — walking and exercise become easier ・1–9 months — coughing and shortness of breath decrease ・1 year — coronary heart disease risk halved ・5+ years — cancer and stroke risks fall significantly Each stage links to its source so you can verify it yourself. ▼ The 30-second urge button When the craving hits, tap "I want a cigarette." A 30-second timer opens, with the angel offering tips and the devil whispering temptations. Most urges peak and fade in well under a minute — getting through 30 seconds is often enough. ▼ Angel & devil companions Two characters react to your progress with short banter that rotates throughout the day. The longer you stay clean, the more the devil "breaks" — getting flustered, conceding, even cheering you on despite himself. No blame, no shame, even if you slip. ▼ Urge log & stats Every urge — whether you endured it or had one — is logged with a timestamp. Look back and see your patterns: which times of day are hardest, how your endurance is growing. ▼ Free, forever. No subscription, no account. All features are free. No sign-up, no cloud sync, no ads in the way of the core experience. Your data stays on your device. ■ Who this is for ・Anyone trying to quit, cut down, or stay quit ・People who've tried serious quit apps and bounced off ・Anyone who wants a little humor and company through withdrawal ■ Important This app is not a medical service and does not provide medical advice. The health recovery information reflects general trends from public sources; individual results vary. If you have heart, respiratory, or other conditions, are pregnant or nursing, please consult a doctor. If you experience severe withdrawal symptoms (persistent dizziness, severe insomnia, depressed mood), please see a healthcare provider. Languages: English, 日本語
