🌿 Zestify — Fresh Meals, Architected for Intelligence

An AI-powered meal planning and smart pantry assistant built for modern Indian kitchens.

---

🚨 Problem Statement

Modern home cooking suffers from:

• Daily decision fatigue
• Pantry invisibility
• Duplicate grocery purchases
• Expired ingredients
• Budget inefficiencies

India alone wastes ~68 million tonnes of food annually due to unplanned consumption.

Existing solutions provide static recipe databases — not intelligent, state-aware systems.

---

💡 Solution Approach

Zestify transforms the kitchen into a reactive data system:

• AI generates structured recipes
• Pantry state persists in Room
• Entitlements dynamically control feature access
• UI reacts to subscription state in real-time

The result: a deterministic, scalable, subscription-ready architecture.

---

🏗 Architecture

Zestify follows MVVM:

• Jetpack Compose (Single Activity)
• Navigation Compose
• Repository Pattern
• Back-stack scoped ViewModels

---

Data Flow Model

UI (Jetpack Compose) -> ViewModel (StateFlow) -> Repository Layer -> Room DB / Gemini API / RevenueCat SDK
