About HealthGPT

HealthGPT is an experimental open-source iOS application developed by the Stanford Biodesign Digital Health team. It allows users to interact with their Apple Health data using natural language queries. Built on the Stanford Spezi digital health development framework, the app provides a chat-style interface that supports speech-to-text and text-to-speech capabilities, as well as chat export functionality. HealthGPT integrates with the Apple Health app via SpeziHealthKit and leverages GPT-3.5 and GPT-4 models for processing queries. The project is intended as an extensible foundation for developers looking to create large language model (LLM) powered apps within the Apple Health ecosystem.
