Open Wearables

Open Wearables Introduction

Open Wearables is an open-source health intelligence platform that provides a single API to connect with all major wearable devices, enabling developers to build personalized health products faster. It includes open health scoring algorithms for metrics like sleep and resilience, developed by a neuroscientist, and an MCP server for AI reasoning over health data. The platform is self-hosted, MIT licensed, and has no per-user fees, making it ideal for scalable health applications.

Use Cases

Health app developers integrating wearable data without multiple API integrations

Research teams analyzing raw wearable data with transparent, auditable scoring algorithms

AI health coaches using structured context from wearable data to personalize recommendations

Startups building scalable health products with cost-effective, open-source infrastructure

Why Startups Use It

Startups need Open Wearables to dramatically reduce integration time and cost when building wearable-powered health products. Its open-source nature and no per-user fees allow startups to scale without expensive licensing, while the transparent health scoring algorithms enable them to offer credible, data-driven insights. This lets startups focus on building unique value rather than reinventing infrastructure.
