QuitNicotine AI

Read full description

Quit nicotine for good with a personalized plan built around your habit, your pace, and your goals. Most people who try to quit rely on willpower alone. QuitNicotine AI is different. It builds a science-backed quit plan around your specific habit and gives you an AI coach available 24/7 to help through the hard moments. The app starts by understanding how you use nicotine — how much, how often, what product, and what triggers your cravings. From there, it generates a personalized daily reduction schedule using proven tapering methods, or supports cold turkey if you prefer. Either way, you get a clear plan from day one. YOUR PERSONAL AI COACH (Pro) Your AI coach is available anytime — at a party, stressed at work, or having a tough morning. It knows your triggers, your progress, and your goals, and gives specific strategies based on where you are in your journey. SMART DAILY TARGETS Each day, you get a clear usage target. Hit it, and your streak grows. Targets adjust week by week, gradually bringing you to zero at a pace that matches your confidence. No sudden drops, just steady progress. QUICK CHECK-INS (Pro) Log your nicotine use in seconds. The app tracks what you used, when, and whether you stayed within target. Over time, check-ins build a complete picture of your quit journey. TRACK YOUR PROGRESS (Pro) See 7-day trends, streaks, and total reduction at a glance. Every step forward is measured so you can see how far you've come. EARN ACHIEVEMENTS (Pro) Your milestones are tracked automatically — first day under target, first full week, longest streak. Share them with friends and family to build your support network. BUILT FOR ALL NICOTINE PRODUCTS Vaping, cigarettes, nicotine pouches, or a mix. The app builds your plan accordingly and shows targets in terms you understand: sessions, cigarettes, or pouches. PRIVATE BY DESIGN All data stays on your device. No account required. No cloud sync. No data collection. Your health data belongs to you. Features marked (Pro) require a QuitNicotine AI Pro subscription. Free trial available. Terms of Use: https://quitnicotineai.com/terms Privacy Policy: https://quitnicotineai.com/privacy
