MacroMate - Macronutrient Tracking App

Overview

MacroMate is a modern and intuitive macronutrient tracking app designed to help users effortlessly monitor and manage their daily nutritional intake. Whether you're aiming to lose weight, build muscle, or maintain a balanced diet, MacroMate provides the tools and insights you need to achieve your health and fitness goals. By leveraging advanced AI technology, specifically OpenAI's GPT-3.5, MacroMate simplifies the process of tracking your diet by automatically providing accurate macronutrient information for various food items.

Key Features

• Daily Macronutrient Overview: MacroMate offers a clear and concise overview of your daily macronutrient intake. The app's main screen displays the total amounts of carbohydrates, proteins, and fats you've consumed throughout the day, making it easy to stay on track with your dietary goals.

• Meal History: Reflecting on your dietary habits is made simple with MacroMate's meal history feature. You can review your macronutrient intake from past meals and analyze trends over time, allowing you to make informed adjustments to your diet as needed.

• AI-Powered Nutrient Analysis: Integrating the power of OpenAI's GPT-3.5, MacroMate allows you to input food items and instantly receive detailed macronutrient information. This AI-powered analysis eliminates the need for manual searches, providing you with quick and accurate nutritional data that updates your daily intake automatically.

• Seamless AI Integration: MacroMate uses a structured function-calling mechanism to interact with GPT-3.5. When you enter a food item, the app sends a request to ChatGPT, which triggers the get_macronutrients function. This function returns the nutritional data in a JSON format, which is then parsed and displayed in the app, ensuring seamless and precise tracking.

• Easy Meal Logging: Adding meals to your daily log is straightforward with MacroMate. By inputting food items and selecting the date, the app calculates the macronutrients for each meal using AI and updates your daily intake accordingly.

• Intuitive Design: The app is designed with the user in mind, featuring a clean and intuitive interface. MacroMate uses consistent design elements, such as rounded buttons and easy-to-read fonts, ensuring a seamless experience as you navigate through your nutritional data.

• Data Storage: MacroMate securely stores all your data, allowing you to access your nutritional history and trends at any time. The app utilizes Core Data for efficient and reliable data management, making sure your progress is always saved and accessible.

Technical Implementation

• SwiftUI Interface: MacroMate is built using SwiftUI, a modern framework that enables the creation of responsive and dynamic user interfaces. Components like VStack, HStack, ScrollView, and NavigationStack are employed to create an engaging and seamless user experience.

• Core Data Integration: Core Data, integrated through SwiftData, manages the persistent storage of your macronutrient data. The app's data model includes entities like Macro, which store details such as food name, date, and macronutrient amounts, ensuring your data is organized and easily retrievable.

• OpenAI API Integration: MacroMate integrates with OpenAI's API to fetch macronutrient data. The OpenAIService class handles the API requests and responses, managing the interaction with GPT-3.5. This includes generating URL requests with necessary headers and payloads, defining functions like get_macronutrients to describe the expected inputs and outputs, and processing responses to extract and display macronutrient data.

• Custom Views: Custom SwiftUI views like MacroHeaderView and MacroDayView are used to display daily macronutrient totals and past meals in an aesthetically pleasing manner. These views are designed to be both informative and visually appealing, enhancing the user experience.

• Error Handling: The app includes robust error handling to ensure a smooth user experience. Whether it's network issues or invalid inputs, MacroMate provides helpful feedback to guide the user, ensuring that any issues encountered are resolved quickly and effectively.

Future Enhancements

• Goal Setting: MacroMate aims to introduce dietary goal setting, allowing users to set daily macronutrient goals and receive notifications when they approach their limits.

• AI-Powered Meal Suggestions: Future versions will offer AI-powered meal suggestions based on users' remaining macronutrient budgets for the day.

• Integration with Health Apps: Plans to integrate with popular health and fitness apps like Apple Health or MyFitnessPal are in the pipeline, providing users with a more comprehensive health management experience.

• Custom Recipes: Users will soon be able to input and calculate the macronutrients for custom recipes, making it easier to track home-cooked meals.

• Analytics Dashboard: An analytics dashboard is also planned, which will show trends and analytics over time, helping users better understand their dietary patterns and make informed decisions about their nutrition.
