Stream Masimo data. No Masimo API needed.
Masimo’s consumer pulse oximeter, the MightySat, will “automatically store your data in Apple Health” — oxygen saturation and heart rate from each spot reading — and Sahha’s SDK reads them into your app as normalized vitals biomarkers, alongside every other source.

Identical schema across 500+ sources
Your users connect Masimo. Sahha does the rest.
This is your user’s side of the story — one screen, once. Sahha ingests every Masimo 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
Masimo 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 — Masimo today, a new watch next year — flows through the same SDK with no extra prompt and no new code.
What Masimo syncs through Apple Health.
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
Masimo, Apple Watch, and Oura all return the same fields and units.
What crosses the bridge
Oxygen saturation and heart rate pass through Apple Health; some app-exclusive metrics may not.

]These are spot readings, not a continuous feed: the user puts a finger in the MightySat, takes a measurement, and that measurement crosses. There’s nothing between readings, so cadence is entirely user-driven. Masimo’s other waveform and perfusion metrics stay in its own app and don’t cross.
Missing a metric you need? Talk to us in the Sahha Slack — if Masimo captures it, we can usually add support.
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 Masimo developer account needed — Sahha reads what Masimo already writes to Apple Health on iOS.
Live in an afternoon, not a sprint.

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 Masimo 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 Masimo data the same day they add the SDK. The only per-source prerequisite: your user has Masimo’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.
Masimo integration questions
How does Sahha get Masimo data?
Masimo’s app automatically stores MightySat readings in Apple Health, and Sahha reads them from there with its mobile SDK — no Masimo API to integrate.
What Masimo data does Sahha receive?
Oxygen saturation and heart rate. Masimo is a clinical-grade pulse oximetry brand and the MightySat is its consumer fingertip device, so those two are what reach Apple Health. The waveform and perfusion metrics Masimo also shows stay in its own app.
Is Masimo data continuous?
No. Each measurement is a spot reading — the user takes one, and that one crosses. Expect gaps between readings rather than a stream, and don’t build logic that assumes overnight or all-day coverage. If you need continuous SpO₂, it will come from a wearable the user also wears, deduplicated into the same schema.
Does the Masimo integration work on Android?
Not today. The verified write path is Apple Health, so this is an iOS-only integration and the page claims nothing more. Your users’ other Android sources still flow through the same Sahha SDK.
Is the Masimo integration HIPAA and GDPR compliant?
Yes. Sahha is HIPAA and GDPR compliant and SOC 2 certified, and Masimo 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.
