Wearable health data, through one API
Access multiple wearables and health apps with ROOK’s API and SDK. Get validated, normalized, and personalized health data delivered to your apps to reduce costs, accelerate innovation, and unlock value.

With ROOK’s API and SDK, access multiple wearables and health data sources in one place. Process, normalize, and deliver personalized health data to maximize value in your applications.
ROOK centralizes the connection to wearables and health apps through a single API and SDK. The platform ingests events, validates and normalizes data, and delivers personalized health information aligned with each product’s needs.
One integration for every wearable
Every day, people generate vast amounts of health data, yet it remains fragmented and inconsistent, making it difficult for companies to use effectively. With its unified API and SDK, ROOK turns this complexity into one consistent data model your product can use.
One integration for multiple data sources
Validated, normalized and ready to use data
Modular Tools & Features
Less integration work per source
What you connect
The sources your users already carry
Wearables, phones, medical devices and labs, reached through one integration instead of one per vendor.
How you connect
Two ways in, one platform behind them
Most products end up using both. The API covers what your servers own, the SDK reaches what only the phone can see, and the data comes out the same shape either way.
API
Runs in your backend
Processed, standardized health data delivered straight into your systems through webhooks or queries, at whatever scale you reach.
- Webhooks push each new record as it lands
- Queries pull history whenever you need it
- No client release to ship a change

- Garmin
- Whoop
- Oura
- Fitbit
SDK
Runs on the device
Connects your user's phone directly to the data it already holds, handling permissions and synchronization so the experience stays inside your app.
- Permission flows handled for you
- Background sync without a server round trip
- Reaches data that never leaves the phone
Read the SDK docsConnects sources like
- Apple Health
- Health Connect
- Samsung Health
What arrives
Data you can act on, not data you have to repair
Raw health data is inconsistent by nature: every vendor names, scales and reports it differently. These four steps happen before it reaches you.
Wearable data for every industry
Health data unlocks value across industries. From fitness to healthcare, wellness, and insurance, ROOK’s API and SDK adapt to diverse needs, enabling products that are more connected, reliable, and impactful.
