Getting wearable data into your app is hard. Making it mean something is harder.

Before you can build anything, you're integrating SDKs one by one: each provider with its own auth flow, data format, and sync quirks. And when the data finally arrives? Heart rate. Steps. Sleep hours. Numbers your users glance at and forget.

Raw wearable data doesn't change behavior. Without an interpretation layer, it's just noise with a nice UI.Open Wearables solves both: one API for every provider, open health scoring algorithms built by health scientists, and an AI-ready data pipeline. Self-hosted on your infrastructure. No black box. No vendor lock-in.

WHAT IS OPEN WEARABLES

From wearable data to health intelligence

One platform. Data ingestion, open scoring algorithms, and AI-ready health context. All self-hosted on your infrastructure.

Unified API Architecture

One API replaces multiple SDKs. Wearable data from any provider flows through a single, consistent interface. Standardized schema across all devices with automatic normalization and deduplication.

Production-ready deployment

Docker Compose or custom infrastructure on AWS, GCP, or Azure. Security hardening, HIPAA-eligible architecture, and audit trail included. What used to take months takes days.

AI-ready data pipeline

Clean, normalized health data flows directly to your LLMs and AI models. Built-in MCP protocol support turns raw wearable signals into structured health context your AI can reason with.

Open health scoring algorithms

Sleep score and resilience score. Every algorithm is open, auditable, and explainable. No black box. Built by health scientists, not just engineers.

Privacy & compliance built in

HIPAA-eligible architecture with end-to-end encryption, user consent management, and data governance. Self-hosted means your data never leaves your infrastructure.

Custom development on top of Open Wearables

Need something beyond the core platform? Momentum builds custom health features on top of Open Wearables: bespoke scoring algorithms, integrations, and product-specific layers.

Self-hosted wearable API. See it in action.

Deploy Open Wearables, connect a wearable provider, and make your first API call in under 5 minutes.

See how the platform connects wearable devices, normalizes the data into a unified model, and exposes it through a single REST API.

One integration instead of building multiple separate OAuth flows.

Who is it for

Built for teams shipping health products at scale

Enterprise health apps

Production-grade wearable infrastructure with compliance built in. For funded health companies with multi-device user bases and engineering teams that can't afford downtime. Self-hosted, HIPAA-eligible, no vendor lock-in.

Longevity & preventive health platforms

Combine biomarker data from any wearable for comprehensive health analysis. Build AI-driven longevity insights grounded in open, auditable algorithms. Ideal for platforms focused on healthspan optimization and personalized wellness protocols.

Corporate wellness & clinical

Deploy privacy-first wellness programs with full data sovereignty. Aggregate individual and team health scores, enable evidence-based interventions, and maintain a complete audit trail. Essential for platforms selling to employers or clinical organizations.
