Open Wearables

Open Wearables

Open infrastructure for wearable-powered health products.

Website openwearables.io
Overview

What it is

Build personalized health products with one API for every wearable. Access wearable data, open health scoring algorithms, and structured context your AI can reason with. Self-hosted, open-source, MIT licensed.

Intent

I need it when

Create AI-powered health recommendations that reason over wearable data trends and anomalies, not just raw metrics

Open Wearables includes an MCP (Model Context Protocol) server that integrates with Claude, ChatGPT, and other LLMs. It provides pre-computed health scores, trend detection, anomaly flagging, and cross-score pattern analysis—structured reasoning framework instead of raw numbers to LLMs.

Integrate Apple HealthKit data into a backend system without building iOS permission flows and HealthKit-specific parsing logic

Open Wearables provides iOS, React Native, and Flutter SDKs that handle HealthKit permissions, on-device sync, and data normalization. Backend receives the same unified schema as other providers, eliminating iOS-specific code in application logic.

Build a health coaching or wellness app that aggregates data from multiple wearable devices without managing separate provider integrations

Open Wearables provides a unified REST API that normalizes data from Garmin, Whoop, Oura, Apple Health, Polar, Suunto, Samsung Health, Google Health Connect, and others into a single schema. Developers write one integration instead of managing provider-specific APIs, reducing time-to-market and maintenance burden.

Audit and customize health scoring algorithms for a specific population or clinical use case

Open Wearables publishes all scoring algorithms (sleep, recovery, strain, HRV, VO2 max) as open source. Developers can fork, inspect every line, and tune thresholds for their user population. Enterprise tier includes custom health score design by the platform's health scientist.

Deploy a health intelligence system on-premises or private infrastructure to maintain full data ownership and compliance control

Open Wearables is self-hosted via Docker Compose on your own infrastructure. Users' health data never leaves your servers. MIT license permits commercial use. HIPAA-eligible architecture and BAA available through Enterprise tier for regulated deployments.

Drop

Not a fit when

  • User requires real-time BLE streaming from wearables during live sessions; Open Wearables fetches from cloud APIs only, not direct device connections
  • User needs to push data back to wearables (e.g., create training plans on Garmin); Open Wearables is read-only
  • User requires managed cloud hosting without self-hosting infrastructure; core platform is self-hosted only (Enterprise custom deployment available but requires negotiation)
  • User needs FHIR-compliant output natively; Open Wearables uses its own data model (FHIR mapping possible as custom layer)
  • User wants proprietary black-box health scoring; Open Wearables emphasizes open algorithms and full source code transparency
