🥭 SnapMango - KitaHack 2026

SnapMango is an AI-powered nutrition and calorie tracking application developed for KitaHack 2026. Our mission is to leverage Google's cutting-edge technologies to contribute to the Sustainable Development Goals (SDGs), specifically focusing on SDG 3: Good Health and Well-being and SDG 2: Zero Hunger.

🌟 Overview

Tracking nutrition is often a tedious and manual task. SnapMango simplifies this by allowing users to simply "Snap" a photo of their meal. Using a Multi-Agent System powered by Google Gemini, the app automatically identifies food items, estimates portion sizes, calculates nutritional data and tracks progress over time.

🚀 Key Features

• AI Food Analysis: Take a photo or upload from the gallery to get instant nutritional facts (Calories, Protein, Carbs, Fat, Fiber).
• Multi-Agent Gemini System: Utilizes specialized AI agents for classification, ingredient identification, and nutritional estimation.
• Weekly Progress Tracking: Visualized pie charts (powered by fl_chart) to monitor weekly calorie consumption against goals.
• Personalized History: A detailed log of all your past meals with high-contrast, easy-to-read reports.
• Gamified User Experience: Smooth transitions and an intuitive, "Mango-themed" UI designed for high engagement.
• Secure Authentication: Robust user management using Firebase Auth and Firestore.

🌍 SDG Alignment

SnapMango directly contributes to:

• SDG 3 (Good Health & Well-being): By providing accessible tools for individuals to understand their nutritional intake and combat lifestyle-related diseases (obesity, diabetes).
• SDG 2 (Zero Hunger/Nutrition): By promoting nutritional awareness and helping users optimize their food consumption.
