QuitSave: Quit Smoking Tracker

A reward-driven quit-smoking tracker that reframes quitting from "how many days did I endure" to "how much money did I save".

Most quit-smoking apps are all-or-nothing: smoke one cigarette and your streak resets to zero. QuitSave is different. Cutting down counts too. Every cigarette you don't smoke is converted into money saved, filling up your savings jar. If you're making progress — even imperfect progress — QuitSave shows you its value.

▸ Savings Jar
• Enter your baseline (cigarettes per day) and pack price — every unsmoked cigarette becomes real-time savings.
• Watch the jar on your home screen fill up with money.
• Log how many you smoked today; smoking less than your baseline still counts as savings. No resets.

▸ Reward Goal D-day
• "What will I buy with the money?" — register something you want with its price as your goal.
• QuitSave estimates your achievement date (D-day) based on your current savings pace.
• Goal progress % and remaining amount at a glance.

▸ Two Kinds of Streaks
• Smoke-free streak — consecutive days without a single cigarette.
• Reduced streak — consecutive days below your baseline. Imperfect days still count.

▸ Health Recovery Timeline
• Body-recovery milestones based on public WHO/CDC data (from blood pressure stabilizing in 20 minutes to lung cancer risk halving in 10 years).
• Visualized as achieved / in progress / upcoming from your quit start date.

▸ Statistics
• Weekly / monthly charts of cigarettes smoked and money saved.
• See your cut-down trajectory as a graph.

▸ Reminders
• Daily local notification at your preferred time so you never forget to log.
• Milestone and goal achievement notifications.

▸ Privacy First
• No sign-up, no account. All data stays on your device.
• Easy device migration with .zip backup & restore.
• Dark mode. English and Korean supported.

The most realistic way to quit smoking is consistency, not perfection. Start with the one cigarette you skipped today — and put it in the jar.
