Introducing Open Wearables: The Open-Source API for Wearable Health Intelligence

Most health apps today only see part of the user's story. They track steps or display heart rate charts from a Fitbit or Apple Watch, but they miss the bigger picture. Your app might know someone exercised yesterday, but not whether they recovered properly according to their Oura Ring sleep data, or if their Whoop recovery score suggests they're ready for another intense workout.

At Momentum, we've spent years building digital health platforms across wellness, fitness, longevity, and clinical care. Again and again, we saw the same problem: wearable integration and building intelligent, personalized health recommendations is still too complex.That's why we're introducing Open Wearables, an open-source platform that transforms fragmented device data into unified, AI-ready health intelligence through seamless wearable API integration.

Why Wearables Integration Is Hard

Each wearable device speaks a different language. To access data from major platforms and devices, you need to integrate multiple SDKs, handle different OAuth flows, and clean up messy formats. Just to start building.

Even then, the wearable data integration doesn't sync. You can't combine heart rate from one device with recovery from another. Your health app may work well on its own, but it stays blind to contextual wearable devices data like sleep quality, recovery status, HRV trends, and daily readiness.

This fragmentation forces developers into an impossible choice: support one wearable device and limit your market, spend months wrestling with wearable integration complexity instead of building health innovations, or pay expensive SaaS platforms that aggregate data but lock you into another vendor dependency.

None of these options serve healthcare innovation. The first limits your reach. The second wastes development resources. The third creates new dependencies while sacrificing control over your users' sensitive health monitoring data.

What Open Wearables Does

Open Wearables is an open-source infrastructure that accelerates personal health app development through one single API. No vendor lock-in. No expensive SaaS for data aggregation. No complex SDKs. Just clean, AI-ready health monitoring data hosted by you.

In just five lines of code, you unlock:

• A single wearable API integration for 200+ wearable devices
• Fully normalized and deduplicated wearable data with consistent timestamps
• OAuth flows handled out of the box
• Ready-to-use schemas for activity, sleep, biometrics, and recovery
• Self-hosted infrastructure for full control and compliance
• AI-ready endpoints for powering insights, scores, or chatbots

Build personalized recovery scores, sleep coaching, or biomarker dashboards without months of SDK work.

What You Can Build

Once you have unified wearable data integration, entirely new possibilities emerge. Fitness platforms can finally deliver coaching that adapts to actual recovery state, not generic training plans. A runner's health app can automatically reduce intensity when HRV drops, or suggest rest days based on poor sleep quality data.

Corporate wellness programs can track meaningful health monitoring trends across their entire workforce, regardless of wearable device preference. Instead of forcing employees onto one wearable brand, companies can support major smartwatch brands, fitness trackers, and specialty devices while still getting standardized analytics.

Longevity platforms can create truly personalized health journeys that track biological age patterns across multiple biomarkers. By combining sleep data from fitness rings, activity from smartwatches, and daily metrics from smartphone health apps, these platforms can reveal insights impossible to see from any single wearable device.

The key difference is context. Open Wearables transforms isolated data points into complete health stories that AI can actually understand and act upon.

The Vision Behind Open Wearables

We are building the open foundation for personalized health intelligence, where any app, coach, or health platform can instantly become data-driven, AI-enabled, and connected to the devices users already love.

Just open, standardized, developer-friendly health data ready to power your next product launch. So your product can see the full picture of your user's health, not just a slice.

This vision reflects our broader philosophy at Momentum: healthcare technology should be transparent, interoperable, and focused on patient outcomes rather than vendor profits. We believe wearable data should accelerate health innovation, not create new barriers.
