Stream Stelo glucose data. No Stelo API needed.
Dexcom’s over-the-counter Stelo biosensor writes continuous glucose to Apple Health and Health Connect — and Sahha’s SDK reads it into your app as a normalized glucose biomarker, alongside every other source.

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

]Stelo shares glucose values on a roughly 3-hour delay — it is a wellness biosensor, not a medical CGM for dosing decisions. This is Dexcom’s over-the-counter path; the prescription Dexcom G-series connects through the cloud-API Dexcom integration instead.

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 Stelo developer account needed — Sahha reads what Stelo already writes to Apple Health and Health Connect.
Live in an afternoon, not a sprint.

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 Stelo 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 Stelo data the same day they add the SDK. The only per-source prerequisite: your user has Stelo’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.
Stelo integration questions
How does Sahha get Stelo data?
The Stelo app writes continuous glucose to Apple Health and Health Connect, and Sahha reads it from there with its mobile SDK — no Stelo API to integrate.
How is Stelo different from the Dexcom integration?
Stelo is Dexcom’s over-the-counter biosensor that writes glucose to Apple Health / Health Connect, so Sahha reads it on-device with the SDK. The prescription Dexcom G-series uses Dexcom’s cloud API instead — a separate, cloud-based Sahha integration.
Do I need a mobile app to use the Stelo integration?
Yes. Because Stelo data lands in Apple Health / Health Connect on the user’s device, you embed the Sahha mobile SDK to read it. Cloud sources like the prescription Dexcom don’t need the SDK, but on-device Stelo does.
Is the Stelo integration HIPAA and GDPR compliant?
Yes. Sahha is HIPAA and GDPR compliant and SOC 2 certified, and Stelo 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.
