ONE ECOSYSTEM. MANY WAYS IN.

Find your integration path.

Understand the device, choose the right interface, and keep the meaning behind every measurement.

The fundamentals

DESIGNED FOR DEVELOPERS

Better questions.
Better integrations.

The first successful reading is a start. A useful product also needs to handle everything around it.

01

Choose where the data comes from.

Device, phone store, or vendor cloud? Let the feature’s timing and scope guide the choice.

02

Keep the context with the value.

Source, unit, time, and missing-data behavior belong in the same design conversation.

03

Build for the imperfect day.

Plan for late sync, declined permissions, duplicate records, and an offline device.

Different devices. Clearer records.Examples

A FEW THINGS, EXPLAINED

Start with
the right questions.

Straightforward answers before you write the first line of integration code.

What does “wear API” actually mean?

It is a broad term for interfaces that connect applications to wearable devices or their data. A device framework, a phone health store, and a vendor cloud API each serve a different access path. The Wear API guide explains how to choose between them.

Is WearAPI.com a live API service?

WearAPI.com publishes developer guides, integration patterns, and educational examples. The examples explain data design; connecting a real device requires the relevant manufacturer or platform interface and the user’s permission.

Can one API connect every smart watch and ring?

Do not assume universal coverage. Device support, available fields, permission behavior, and delivery timing depend on the interface. Confirm the specific devices and measurements your application needs before choosing an integration.

What is the difference between heart rate and RR intervals?

Heart rate is commonly expressed in beats per minute. RR intervals describe the time between successive beats. They are distinct data types, and a source that provides heart rate may not expose intervals or a raw waveform.

Does AI clothing mean virtual try-on?

Here, AI clothing refers to sensor-equipped garments and inference based on physical signals. Virtual try-on works with images of people and clothing; it is a separate integration problem.

Where should a new developer begin?

Start with one useful outcome, one source, and the smallest permission scope that supports it. Use the Docs and sample records to think through timestamps, missing values, and source context before connecting a real device.
