Wyze Integration

Stream Wyze data. No Wyze API needed.

Wyze smart scales write weight, body fat, BMI, and lean mass to Apple Health — and Sahha’s SDK reads them into your app as normalized body-composition biomarkers, alongside every other source.

How it works

Your users connect Wyze. Sahha does the rest.

This is your user’s side of the story — one screen, once. Sahha ingests every Wyze signal, normalizes, deduplicates, and delivers it to your service — raw, or as refined intelligence your product can act on.

Waiting for data…

On-device and permissioned

Wyze data is read on the user’s own device, only after they grant Apple Health permission — nothing syncs without consent.

One integration, every source

Permission is per data type, not per brand. Anything that writes to Apple Health — Wyze today, a new watch next year — flows through the same SDK with no extra prompt and no new code.

Request only what you need
You choose exactly which of these signals to request from Apple Health — users are only ever prompted for those, which keeps opt-in rates high.
One schema, every source
Wyze, Apple Watch, and Oura all return the same fields and units.
What crosses the bridge
Weight, body fat, BMI, and lean mass pass through Apple Health; some app-exclusive metrics may not.

Wyze writes body-composition readings — weight, body fat, BMI, and lean mass — to Apple Health each time the user steps on the scale. It’s an iOS integration, so its data lands in Apple Health, not Health Connect.

Sahha reads and delivers
Once permission is granted, the SDK reads Wyze data from Apple Health in the background, normalizes it to one schema, and streams it to your app by webhook or API.

Start building Read the SDK docs

Most teams read live Wyze data the same day they add the SDK. The only per-source prerequisite: your user has Wyze’s Apple Health sync switched on — most source apps enable it by default.

Destinations

Route it into your stack.

Sahha streams every update to your webhook — and a step-by-step guide takes it the rest of the way into your database, CDP, or messaging tool.

FAQ

Wyze integration questions

How does Sahha get Wyze data?

Wyze scales write to Apple Health through the Wyze app, and Sahha reads them from there with its mobile SDK — so you get body-composition data without integrating the Wyze API directly.

Which Wyze metrics does Sahha provide?

Weight, body fat percentage, BMI, and lean body mass — normalized to Sahha’s schema. These are spot readings taken each time the user weighs in.

Does the Wyze integration work on Android?

Wyze scales write to Apple Health on iOS, so Sahha reads them there. The same Sahha SDK also reads Health Connect on Android for your other sources, all normalized to one schema.

Is the Wyze integration HIPAA and GDPR compliant?

Yes. Sahha is HIPAA and GDPR compliant and SOC 2 certified, and Wyze data flows through the same compliant pipeline as every other source.
