Open Wearables 0.2.1: Whoop Integration and Mobile SDK Authentication

Momentum has released Open Wearables 0.2.1, adding Whoop as the fourth major provider integration alongside comprehensive authentication improvements. This release focuses on expanding device coverage and providing the infrastructure developers need for mobile applications.

What's New in 0.2.1

Whoop Integration

Brings one of the most requested providers to the platform. The integration handles sleep metrics and workout data through the same normalized API structure used for existing providers. Developers can now access:

• Recovery scores and strain metrics
• Sleep stages and efficiency data
• Training data and workout summaries
• All through the unified Open Wearables API without separate integration logic

SDK User-Scoped Token Authentication

Enables secure mobile app development with individual user tokens that mobile SDKs can use independently. Essential for building apps where users connect their own wearables directly from their phones.

• Individual user token generation
• Mobile SDK compatibility
• Secure authentication flows
• Independent user data access

Sleep Summaries Endpoint

Aggregates daily sleep data across all providers. Rather than processing individual sleep events, developers can query consolidated daily metrics:

• Total sleep time across all connected devices
• Sleep efficiency scores
• Sleep stage breakdowns (REM, deep sleep, light sleep)
• Consistent format regardless of source provider

Backend E2E Integration Guide

Comprehensive documentation for production implementations covering:

• Authentication flows and token management
• Data synchronization patterns
• Error handling and retry logic
• Monitoring and logging best practices
• Production deployment considerations

Community Contributions

This release showcases the growing Open Wearables contributor community. Community members implemented the complete Whoop integration, built the SDK authentication system, and contributed numerous fixes and improvements across the platform.

The community-driven approach means device integrations expand based on actual developer demand rather than vendor partnerships, ensuring the platform addresses real integration challenges.

Production-Ready Infrastructure

The platform maintains its focus on production reliability with comprehensive testing coverage and standardized development practices. The AI agent configuration system ensures external contributors follow established patterns, keeping the codebase maintainable as the project scales.

The sleep summaries endpoint demonstrates the platform's evolution from raw data aggregation to analytics-ready infrastructure. Daily aggregation reduces API calls while providing the summary metrics most health applications require.

Coming Soon

Apple Health Flutter Integration is entering final testing. The Flutter SDK will handle HealthKit permissions, background synchronization, and data normalization automatically. The accompanying demo app will showcase end-to-end wearable data sync using Open Wearables infrastructure.

This mobile integration completes the technical foundation needed for consumer health applications, providing both cloud provider connections (Whoop, Garmin, Polar, Suunto) and local device access (Apple Health) through unified APIs.

Getting Started

Open Wearables 0.2.1 is ready for development teams building health applications with Whoop integration requirements.

Clone the repository and run make init to get started with sample data from all supported providers including Whoop. The platform includes working authentication flows, comprehensive API documentation, and the new Backend E2E Integration Guide at docs.openwearables.io

The SDK authentication system enables immediate mobile development while the sleep summaries endpoint provides analytics-ready data for dashboard and insight features.
