Biostrap Integration

Stream Biostrap data. No Biostrap API needed.

Biostrap’s clinical-grade band syncs heart rate, HRV, SpO₂, respiratory rate, and sleep to Apple Health and Health Connect — and Sahha’s SDK reads them into your app as normalized biomarkers and scores, alongside every other source.

How it works

Your users connect Biostrap. Sahha does the rest.

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

On-device and permissioned

Biostrap 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 — Biostrap today, a new watch next year — flows through the same SDK with no extra prompt and no new code.

Data coverage

What Biostrap syncs through Apple Health & Health Connect.

Works with EVOKairos

Request 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
Biostrap, Apple Watch, and Oura all return the same fields and units.
What crosses the bridge
Sleep, heart rate, HRV, SpO₂, and respiratory rate pass through the platform; some device-exclusive metrics may not.

Biostrap writes clinical-grade heart rate, HRV, SpO₂, respiratory rate, sleep, and steps to Apple Health and Health Connect. Which metrics appear depends on what the platform exposes.

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.

Build it yourself

With Sahha

Every device

Build it yourself

Integrate Apple Health.
Then Health Connect, separately.
Then reconcile the two.

With Sahha

One SDK covers Apple Health, Health Connect, and every cloud source.

Getting the data

Build it yourself

Write the HealthKit queries.
Write the Health Connect queries.
Wire up background delivery.

With Sahha

The SDK handles queries, permissions, and background sync.

Keeping it clean

Build it yourself

Dedupe apps writing the same metric.
Map dozens of platform types.
Normalize iOS against Android.

With Sahha

Deduped, typed, one schema — one stream per user.

Turning it into insight

Build it yourself

Build a sleep model.
Build an activity model.
Hire a data scientist.

With Sahha

Scores, archetypes, and insights — built in.

Keeping it alive

Build it yourself

Apple or Google changes an API.
You find out in production.

With Sahha

We version the SDK. You never notice.

No Biostrap developer account needed — Sahha reads what Biostrap already writes to Apple Health and Health Connect.

Setup

Live in an afternoon, not a sprint.

# Add the Sahha SDKnpm install sahha-react-native
01
Add the Sahha SDK
Drop the Sahha SDK into your iOS or Android app — or React Native or Flutter. One dependency covers both Apple Health and Health Connect.

02
Prompt for health permissions
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 Biostrap data from Apple Health / Health Connect 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 Biostrap data the same day they add the SDK. The only per-source prerequisite: your user has Biostrap’s Apple Health / Health Connect 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

Biostrap integration questions

How does Sahha get Biostrap data?

Biostrap writes to Apple Health and Health Connect, and Sahha reads it from there with its mobile SDK — so you get Biostrap data without integrating the Biostrap API directly.

Which Biostrap metrics does Sahha provide?

Sleep stages, heart rate, resting heart rate, HRV, blood oxygen, respiratory rate, steps, and energy — all normalized to Sahha’s schema, plus Sleep, Readiness, and Activity scores and archetypes.

Do I need a mobile app to use the Biostrap integration?

Yes. Because Biostrap data lands in Apple Health / Health Connect on the user’s device, you embed the Sahha mobile SDK to read it. Cloud-only sources like Oura don’t need the SDK, but on-device sources like Biostrap do.

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 Biostrap integration HIPAA and GDPR compliant?

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