HealthGPT

HealthGPT is an experimental iOS app based on Stanford Spezi that allows users to interact with their health data stored in the Apple Health app using natural language. The application offers an easy-to-extend solution for those looking to make large language model powered apps within the Apple Health ecosystem.

The initial prototype based on Spezi (formerly CardinalKit) and the SpeziTemplateApplication was built by Varun Shenoy.

Features

• Chat-style interface for user-friendly health data interaction
• Integration with the Apple Health app to ensure seamless first-party data usage
• Extensible architecture built on Stanford Spezi for easy customization
• GPT-3.5 + GPT-4 access through the OpenAI Swift module
• Out of the box support for querying sleep, step count, active energy, exercise minutes, heart rate, and body mass.

Disclaimer

HealthGPT is provided for general informational purposes only and is not intended as a substitute for professional medical advice, diagnosis, or treatment. Large language models, such as those provided by OpenAI, are known to hallucinate and at times return false information. The use of HealthGPT is at your own risk. Always consult a qualified healthcare provider for personalized advice regarding your health and well-being. Aggregated HealthKit data for the past 14 days will be uploaded to OpenAI. Please refer to the OpenAI privacy policy for more information.

Set Up

1. Clone this 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. You can also paste your key into the app during onboarding.
4. Run the app (on device or in the simulator) and play with HealthGPT on your own data 🚀

Note: if you're using the simulator, you will need to manually add data in the Health app. Otherwise, all of your results will read zero.

You can add queries for additional HealthKit quantities and categories as follows:

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