GitHub - StanfordBDHG/HealthGPT: Query your Apple Health data with natural language 💬 🩺

Features:

• Chat-style interface for user-friendly health data interaction
• Integration with the Apple Health app for seamless first-party data usage
• Extensible architecture built on CardinalKit for easy customization
• GPT-3.5 and GPT-4 access through the OpenAI Swift module

Disclaimer: HealthGPT is not a substitute for professional medical advice, diagnosis, or treatment. Users should consult a qualified healthcare provider for personalized advice regarding their health and well-being. The use of HealthGPT is at your own risk.

Getting Started:

1. Clone the HealthGPT repository.
2. Open HealthGPT.xcodeproj in Xcode. Wait for all dependencies to install and indexing to finish.
3. Replace the OpenAI API key placeholder in Supporting Files/OpenAI-Info.plist with your own from OpenAI’s dashboard.
4. Run the app (on device or in the simulator) and start interacting with HealthGPT using your own health data.

Note: If using the simulator, you will need to manually add data in the Health app; otherwise, all results will read zero.

Adding Queries for Additional HealthKit Quantities and Categories:

1. Edit HealthGPT/HealthGPT/HealthDataFetcher.swift to create an appropriate query for your data type.
2. Update the prompt in HealthGPT/HealthGPT/MessageInputView.swift to pass the newly acquired data to the OpenAI API.

For any other quick changes, such as adding an onboarding flow, refer to the CardinalKitTemplateApplication repo.

HealthGPT is an innovative app that makes it simple for users to analyze and interact with their health data using natural language. With its user-friendly interface, seamless integration with Apple Health, and extensible architecture, HealthGPT is an excellent starting point for developers interested in creating large language model-powered health apps within the Apple Health ecosystem.
