Insights on wearable data,
health AI, and open source.
Articles on building with wearable data, health scoring algorithms, and the Open Wearables platform.
What Is an Open Source Wearable API and When Does It Make Sense
An open source wearable API gives you the integration code itself, not just an endpoint. Here is what that means in practice, what Open Wearables provides, and when this approach fits your product.
How to Add Wearable Support to an Existing Health App in Days, Not Months
Adding wearable support to an existing app does not require rebuilding your data layer. Open Wearables sits alongside your backend. Here is what the integration looks like and how long each step actually takes.
How to Handle OAuth, Webhooks, and Token Refresh Across Multiple Wearable Providers
Every wearable provider implements OAuth differently, delivers data through a different mechanism, and has different token lifecycle rules. Here is how Open Wearables abstracts all of it and what your application still needs to handle.
How to Give Your LLM Access to Wearable Data
Most LLM integrations with health data dump raw numbers into context and hope for the best. Here is how to use the Model Context Protocol with Open Wearables so your LLM queries the right data and reasons about it.
How to Build a HIPAA-Compliant Health App That Uses Wearable Data
HIPAA compliance starts with where data lives. Open Wearables is self-hosted: wearable data stays on your infrastructure. Here is what the platform provides and what you need to configure yourself.
What wearable app development actually looks like in 2026
Most tutorials about wearable app development skip the hard parts. This article shows where the complexity actually lives: OAuth flows, token refresh, normalization, webhook-only providers. And what you can take off the shelf with Open Wearables.
The wearable app development checklist: what you actually need to build (and what you don't)
Scoping a wearable feature is harder than it looks. This checklist maps what you actually need to build, what Open Wearables handles for you, and what you will still own no matter what.
Open Wearables 0.6.0: Women's Health & FIT Files
Open Wearables 0.6.0 adds Garmin menstrual cycle tracking, a FIT file parser with second-by-second workout data, Oura reliability fixes, and multi-account sync support. No breaking changes to the API.
Google Health Connect integration for Android developers
Google Health Connect is not a cloud API. It requires on-device Android SDK integration. Learn how Open Wearables handles the full Health Connect lifecycle.
Samsung Health API integration guide for Android developers
Samsung Health API is not a cloud API. It requires an on-device SDK. Learn how Open Wearables Android SDK handles permissions, background sync, and normalization.
How to integrate Apple Health API into your backend
There is no Apple Health API in the traditional sense. Learn how Open Wearables SDK-based approach gets HealthKit data into your backend with token-based auth and XML import.
How to integrate Whoop API data into your health app
The Whoop API requires a paid membership and OAuth setup. Learn how Open Wearables handles authentication, polling, and normalization so you query one endpoint.
How to integrate Suunto data into your health app
The Suunto API provides workouts and 24/7 continuous monitoring. Open Wearables handles OAuth, polling, and normalization so you query one endpoint instead of building provider logic.
Strava API integration guide for health and fitness apps
The Strava API requires OAuth, token refresh, and normalization. Learn how Open Wearables abstracts all of that into one sync endpoint alongside other providers.
How to integrate Polar data into your health app
The Polar API (AccessLink) requires OAuth, token management, and polling. Open Wearables abstracts all of that into a single sync endpoint with normalized output.
