Tired of failing at cold turkey? Next15 helps you quit smoking gradually — your interval grows by 15 minutes after each cigarette. Track every cigarette, watch your intervals grow, and reduce nicotine step by step. Slipped up? The app won't reset your progress — it supports you with a soft rollback. The 15-minute method allows your body and mind to adapt to reduced nicotine without harsh restrictions. The app tracks honest statistics, reminds you of your goals through personalized motivation cards, and helps you maintain the right interval with convenient timers (Live Activity) that work even on your locked screen. Key features: • Smart Timer: You know exactly when you can take a smoke break and when to wait. The app automatically increases the interval by 15 minutes when you're ready. • "Freedom" Mode: Decided to quit for good? Start the total freedom counter and take pride in every minute without tobacco. • Motivation Cards: Add your own reasons to quit (health, savings, family) and they'll support you right on the main screen. • Honest Statistics: Track the number of cigarettes smoked per day and your overall progress. • Live Activity Widgets: The timer is always in front of your eyes right on your iPhone's lock screen, so you never miss a break time. Remember: Next15 is a tool. The key is within you. If you've truly decided to quit, we'll help make this journey comfortable and clear.
