+> **This project has evolved into [Open Wearables](https://github.com/the-momentum/open-wearables)** - Self-hosted platform to unify wearable health data from multiple devices, including Apple Health. Open Wearables also provides an MCP server and a companion app for **continuous Apple Health data sync**, eliminating the need for manual XML exports. Check it out: [github.com/the-momentum/open-wearables](https://github.com/the-momentum/open-wearables)
