🍎 Foodlyze – Smart Food Information Scanner

Foodlyze is a mobile application designed to revolutionize how people interact with food products. In an era where health-conscious decisions are increasingly vital, Foodlyze empowers users to scan product barcodes and access comprehensive data about their nutritional profile, allergen risks, ingredient quality, and overall naturalness. With an intuitive interface and real-time scanning capabilities, it transforms smartphones into personal food advisors.

🚀 Features

🌍 Barcode Scanning: Real-time recognition and identification of food products using device camera and ML Kit.

💥 Allergen Detection: Instant alerts for common allergens like gluten, lactose, nuts, and soy.

🌿 Naturalness Score: Quantitative analysis of how "natural" a product is based on preservatives, colorants, and artificial additives.

🌟 Nutritional Breakdown: Calories, macronutrients, and micronutrient details visualized in a clean dashboard.

📊 Ingredient Insights: Color-coded indicators show healthy vs. unhealthy ingredients.

🔍 Search History: Previous scans are saved for offline access and tracking.

🧠 Technologies Used

Foodlyze leverages modern mobile and cloud technologies to ensure fast performance, scalability, and seamless user experience:

Android Studio – Official IDE for Android development

Kotlin / Java – Robust languages for scalable and readable code

Firebase Suite:

Authentication – Secure login and user management

Realtime Database & Firestore – Storage for scanned product history and user preferences

Firebase Storage – For storing scanned image previews

Google ML Kit Barcode API – For accurate and fast barcode detection

Open Food Facts API – Open-source food product database used for detailed nutritional and ingredient information

Jetpack Libraries – LiveData, Navigation Component, ViewModel for lifecycle-aware architecture

Retrofit – For efficient REST API communication

Gson – For parsing JSON data from APIs

🌟 Innovation & Social Impact

Foodlyze addresses a real-world problem: lack of transparency in packaged food. While most people check calorie counts, very few understand what ingredients like E250 or sodium nitrate truly mean. Foodlyze decodes these terms in real-time, making food literacy accessible to everyone.

Key Contributions:
