Stream Myzone data. No Myzone API needed.
Myzone writes activity calories and body composition — weight, BMI, and body fat — to Apple Health and Health Connect, and Sahha’s SDK reads them into your app as normalized biomarkers, alongside every other source.

Identical schema across 500+ sources
Your users connect Myzone. Sahha does the rest.
This is your user’s side of the story — one screen, once. Sahha ingests every Myzone signal, normalizes, deduplicates, and delivers it to your service — raw, or as refined intelligence your product can act on.
A Allow "your app"
On-device and permissioned
Myzone data is read on the user’s own device, only after they grant Apple Health or Health Connect permission — nothing syncs without consent.
One integration, every source
Permission is per data type, not per brand. Anything that writes to Apple Health or Health Connect — Myzone today, a new watch next year — flows through the same SDK with no extra prompt and no new code.
What Myzone syncs through Apple Health & Health Connect.
Works with
MZ-SwitchMZ-3MZ-60MZ-RemoteRequest only what you need
You choose exactly which of these signals to request from Apple Health / Health Connect — users are only ever prompted for those, which keeps opt-in rates high.
One schema, every source
Myzone, Apple Watch, and Oura all return the same fields and units.
What crosses the bridge
Calories and body composition pass through the platform; some device-exclusive metrics may not.

]Myzone writes activity calories and body-composition readings — weight, BMI, BMR, and body fat — to Apple Health and Health Connect. It reads heart rate from the platform to calculate MEPs rather than writing heart rate itself.

Get more than just raw data
Sahha turns these signals into biomarkers, scores, archetypes, and insights — the modeling done for you.
Reading Apple Health and Health Connect yourself? Here’s the to-do list.
Everything on the left is yours to write, test, and maintain across two platforms. Everything on the right, Sahha already did.
- Integrate Apple Health.
- Then Health Connect, separately.
- Then reconcile the two.
One SDK covers Apple Health, Health Connect, and every cloud source.
- Write the HealthKit queries.
- Write the Health Connect queries.
- Wire up background delivery.
The SDK handles queries, permissions, and background sync.
- Dedupe apps writing the same metric.
- Map dozens of platform types.
- Normalize iOS against Android.
Deduped, typed, one schema — one stream per user.
- Build a sleep model.
- Build an activity model.
- Hire a data scientist.
Scores, archetypes, and insights — built in.
- Apple or Google changes an API.
- You find out in production.
We version the SDK. You never notice.
No Myzone developer account needed — Sahha reads what Myzone already writes to Apple Health and Health Connect.
Live in an afternoon, not a sprint.

Drop the Sahha SDK into your iOS or Android app — or React Native or Flutter. One dependency covers both Apple Health and Health Connect.

Call the SDK to show the native Apple Health or Health Connect consent sheet. The user chooses what to share — under your brand. It’s one prompt, ever: permission is per data type, not per brand, so every future source is already covered.

Sahha reads and delivers
Once permission is granted, the SDK reads Myzone data from Apple Health / Health Connect in the background, normalizes it to one schema, and streams it to your app by webhook or API.
Most teams read live Myzone data the same day they add the SDK. The only per-source prerequisite: your user has Myzone’s Apple Health / Health Connect sync switched on — most source apps enable it by default.
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.
Myzone integration questions
How does Sahha get Myzone data?
Myzone writes activity calories and body-composition data to Apple Health and Health Connect, and Sahha reads them from there with its mobile SDK — so you get Myzone data without integrating the Myzone API directly.
Does Sahha get heart rate or MEPs from Myzone?
No. Myzone reads heart rate from Apple Health to calculate its MEPs — it doesn’t write heart rate or MEPs back to the platform. Sahha receives Myzone’s activity calories and body-composition metrics, and heart rate from any other source a user connects.
Which Myzone metrics does Sahha provide?
Activity calories, weight, body fat, BMI, and height — normalized to Sahha’s schema.
Does it work on both iOS and Android?
Yes. The same Sahha SDK reads Apple Health on iOS and Health Connect on Android, and normalizes both to one schema.
Is the Myzone integration HIPAA and GDPR compliant?
Yes. Sahha is HIPAA and GDPR compliant and SOC 2 certified, and Myzone data flows through the same compliant pipeline as every other source.
One API for every other source, too.
Add another wearable or app and the schema, webhooks, and scores are identical — no new pipeline to build.
