The wearable data integration nightmare ends here

Building with wearable data means wrestling with 6+ different SDKs, inconsistent data formats, and months of integration work. Apple Health requires native mobile apps, Garmin uses webhooks, Fitbit has rate limits, and Oura needs OAuth—each speaking a different language. Meanwhile, your competitors are shipping AI-powered health insights while you're still debugging API calls.

what you get

From fragmented APIs to unified health intelligence

Unified API Architecture

One API replaces 6+ SDKs. Access Apple Health, Garmin, Fitbit, Oura, and Strava through a single, consistent interface. Standardized schema across all providers with automatic data normalization and deduplication.

Lightning-Fast Integration

Go from prototype to production in days, not months. Pre-built authentication flows, OAuth management, and mobile bridges for Apple Health. Self-hosted deployment with Docker in under 5 minutes.

AI-Ready Data Pipeline

Transform raw sensor data into health intelligence. Built-in MCP protocol support for AI agents, with chatbot SDK and conversational health interfaces. Your data flows directly to LLMs for personalized insights.

Mobile-First by Design

Native iOS bridge for Apple Health access, with Flutter SDK for seamless mobile integration. Handle local permissions, background sync, and secure data transfer automatically.

Privacy & Compliance Built-In

HIPAA-ready architecture with end-to-end encryption, user consent management, and data governance. Self-hosted means you control the data—no vendor lock-in, ever.

Developer Dashboard & Analytics

Monitor API usage, track user connections, and manage wearable integrations through a clean developer portal. Real-time sync status, error handling, and performance metrics included.

use cases
