Stream Qardio data. No Qardio API needed.
Qardio’s blood-pressure monitors and smart scale write blood pressure, heart rate, and weight to Apple Health — and Sahha’s SDK reads them into your app as normalized biomarkers, alongside every other source.

Identical schema across 500+ sources
Your users connect Qardio. Sahha does the rest.
This is your user’s side of the story — one screen, once. Sahha ingests every Qardio 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
Qardio 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 — Qardio today, a new watch next year — flows through the same SDK with no extra prompt and no new code.

QardioArmQardioBaseQardioCoreRequest 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
Qardio, Apple Watch, and Oura all return the same fields and units.
What crosses the bridge
Blood pressure, heart rate, and weight pass through Apple Health; some app-exclusive metrics may not.

]Qardio’s QardioArm, QardioBase, and QardioCore write blood pressure, heart rate, and weight to Apple Health. It’s an iOS integration, so its data lands in Apple Health — not Health Connect.

Get more than just raw data
Sahha turns these signals into biomarkers, scores, archetypes, and insights — the modeling done for you.
Reading Apple Health yourself? Here’s the to-do list.
Everything on the left is yours to write, test, and maintain on iOS. Everything on the right, Sahha already did.
- Integrate Apple Health.
- Handle iOS version differences.
- Add Health Connect separately for Android.
One SDK covers Apple Health, Health Connect, and every cloud source.
- Write the HealthKit queries.
- Request the right permissions.
- Wire up background delivery.
The SDK handles queries, permissions, and background sync.
- Dedupe apps writing the same metric.
- Map dozens of HealthKit types.
- Reconcile against your Android sources.
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 changes a HealthKit API.
- You find out in production.
We version the SDK. You never notice.
No Qardio developer account needed — Sahha reads what Qardio already writes to Apple Health on iOS.
Live in an afternoon, not a sprint.

Add the Sahha SDK
Drop the Sahha SDK into your iOS app — or React Native or Flutter. The same SDK also covers Health Connect for your Android sources.

Sahha reads and delivers
Once permission is granted, the SDK reads Qardio data from Apple Health in the background, normalizes it to one schema, and streams it to your app by webhook or API.
Most teams read live Qardio data the same day they add the SDK. The only per-source prerequisite: your user has Qardio’s Apple Health 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.
Qardio integration questions
How does Sahha get Qardio data?
The Qardio app writes blood pressure, heart rate, and weight to Apple Health, and Sahha reads them from there with its mobile SDK — no Qardio API to integrate.
Does the Qardio integration work on Android?
Sahha reads Qardio through Apple Health on iOS. The same Sahha SDK also reads Health Connect on Android for your other sources, all normalized to one schema.
Do I need a mobile app to use the Qardio integration?
Yes. Because Qardio data lands in Apple Health 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 Qardio do.
Is the Qardio integration HIPAA and GDPR compliant?
Yes. Sahha is HIPAA and GDPR compliant and SOC 2 certified, and Qardio 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.
