# MyFoodBuddy - Complete Information

## Product Overview
MyFoodBuddy is a voice-powered calorie tracking iOS app. Users describe what they ate in natural language and AI extracts full nutritional breakdowns automatically. The app is designed for people who have tried and quit other calorie trackers because they were too tedious.

## How It Works
1. User speaks or types what they ate (e.g., "two eggs, toast with butter, coffee with oat milk")
2. AI identifies each food item and pulls accurate nutrition data from USDA and brand databases
3. User reviews the breakdown, adjusts portions if needed, and taps to log
