The most beautiful and private way to track your smoking habits. 100% Offline & Private. No sign-ups, no ads. Just honest insights and satisfying haptics.
"Just One" is a beautifully crafted companion designed to help you understand and control your smoking habits without the guilt or complexity of traditional trackers.
Designed with a philosophy of "Honest Reflection," Just One moves beyond simple counting. It analyzes your daily patterns, assigns a performance grade (S to D), and helps you visualize not just how much you smoke, but how much you save—both in money and health impact.
Key Features:
Premium Experience: A satisfying "Liquid Glass" interface with immersive haptic feedback that makes every interaction feel real.
Privacy First: Your data belongs to you. Built with SwiftData and CloudKit, everything stays on your device or your private iCloud. No servers, no tracking, no accounts.
Smart Grading: Receive a daily "Smoking Grade" (S, A, B, C, D) based on your goals. It’s like a credit score for your lung health.
Dynamic Insights: See real-time calculations of money spent and tar/nicotine intake.
Intelligent Notifications: Forget generic reminders. Just One analyzes yesterday’s data to send you personalized encouragement or gentle warnings.
Weekly Reports: Detailed breakdowns of your weekly progress to help you spot trends and cut back effectively.
Take control, one tap at a time.
