HEALTHY CHOICES - FOOD TRACKING MOBILE APP

Project Brief.
HealthyChoices iOS App Development Objective.
To create an iOS application, HealthyChoices, that enables users in the USA to make healthier grocery shopping decisions by scanning food products, analyzing ingredients, and providing information on chemical-free options.
Scope of Work The developer will be responsible for building a fully functional iOS app that includes barcode scanning, a product database integration, health scoring, alternative suggestions, and a clean, intuitive user interface.
This project is for an iOS-only app, and it should be optimized for iPhones.
Core Features 1.
Barcode Scanning • Objective.
Allow users to scan barcodes to retrieve product information.
• Requirements.
Integrate a barcode scanning library (such as AVFoundation).
• Functionality.
Upon scanning, the app should use the barcode to look up product information from the database.
2.
Product Information Retrieval • Objective.
Pull product data (nutritional info, ingredients, etc.) from reliable sources.
• Data Sources.
Use available public APIs like.
• Open Food Facts API.
For an extensive product database.
• Nutritionix API.
For additional nutritional data.
• USDA FoodData Central API.
For comprehensive food details.
• Functionality.
Retrieve and display nutritional details, ingredient lists, and chemical information for each product.
3.
Health Scoring Algorithm • Objective.
Provide a health score based on key factors, including nutritional value, presence of additives, and organic certification.
• Requirements.
Implement a scoring system to assess products based on.
• Nutritional Value (e.
., calories, sugars, sodium).
• Additives (highlight harmful chemicals/additives).
• Organic Status (assign higher scores for organic products).
• Functionality.
Display the score prominently, explaining each component of the score.
4.
Alternative Product Suggestions • Objective.
Recommend healthier or chemical-free alternatives within the same category.
• Requirements.
Use a content-based filtering logic that matches products by category and ranks by health score.
• Functionality.
Offer healthier alternatives if the scanned product does not meet certain criteria 5.
User Profile and Preferences • Objective.
Allow users to create profiles, save their favorite products, and customize dietary preferences (e.
., organic only, chemical-free).
• Functionality.
Users should be able to register an account, view saved products, and set personal health goals or preferences.
6.
User Interface (UI) • Design Requirements.
Clean, user-friendly layout with intuitive navigation.
Prioritize ease of use and accessibility.
• Visual Indicators.
Use colors, icons, or symbols to visually convey health scores (e.
., green for healthy, red for caution).
• User Testing.
Design should be user-tested to confirm clarity and ease of use.
Technical Requirements 1.
Development Language.
Swift, using Xcode as the development environment.
2.
APIs Integration.
• Open Food Facts API, Nutritionix API, and USDA FoodData Central API for data retrieval.
• Custom API development may be necessary for managing unique app-specific data and product scoring.
3.
Data Storage.
• Use a database (such as Firebase or Core Data) to store user information, scanned products, and personalized preferences.
4.
Backend Services.
• Set up cloud services (AWS or Firebase) to handle user profiles, favorites, and product data efficiently.
5.
Security and Compliance.
• Ensure secure data handling, especially for user data (implement encryption in transit and at rest).
• Comply with data privacy regulations relevant to the US (e.
., CCPA compliance).
6.
Testing and QA.
• Regular testing is required to verify the functionality and usability of the app across different iOS devices.
Deliverables 1.
HealthyChoices iOS App.
Fully functioning, tested app ready for submission to the Apple App Store.
2.
Documentation.
• Code documentation to explain key parts of the app, especially around custom algorithms or integrations.
• Setup and deployment instructions.
3.
Source Code.
All source code for the project.
4.
Maintenance Plan (optional).
If you offer maintenance, outline any ongoing support or updates post-launch.
Additional Notes • User Data Privacy.
The app should respect user privacy, allowing users to opt-out of data collection and providing transparency around how their data is used.
• Data Completeness.
If the API does not have certain products, include a system that allows users to manually add or update product data (optional).
The app should be available on iOS devices.
The UI should follow a minimalist and clean design, focusing on simplicity and user-friendliness.
