Stream Hume Health data. No Hume API needed.
Hume Health (published by FitTrack Inc) makes a smart scale and a wearable Band, and the Hume app writes its Band metrics — steps, heart rate, sleep, and active energy — to Apple Health and Health Connect, where Sahha’s SDK reads them into your app as normalized biomarkers, alongside every other source.

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

]What’s confirmed here is the Hume Band: steps, heart rate, sleep, and active energy. Body composition is not confirmed to cross — no primary source shows Hume’s body-fat or lean-mass measurements reaching Apple Health or Health Connect, and where a Hume scale does write, it arrives as weight. Hume’s own guidance also notes that not all Hume metrics have direct equivalents in Apple Health or Google Fit, that the Hume app needs permission to write data, and that data typically syncs to health platforms only after being processed in the Hume app — so expect a lag rather than a live feed.

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

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.

ConnectSleepActivityHeart rate02Prompt 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 Hume Health 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 Hume Health data the same day they add the SDK. The only per-source prerequisite: your user has Hume Health’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.
Hume Health integration questions
How does Sahha get Hume Health data?
The Hume app writes its Band metrics to Apple Health and Health Connect once they’ve been processed, and Sahha reads them from there with its mobile SDK — no Hume API to integrate.
Does Sahha get body composition from the Hume scale?
Not confirmed. No primary source shows Hume’s body-composition measurements — body fat and lean mass — reaching Apple Health or Health Connect, so we don’t claim them. Where a scale reading does cross, it arrives as weight. Hume also notes that not all Hume metrics have direct equivalents in Apple Health or Google Fit.
Why might Hume metrics be missing from Apple Health or Health Connect?
Hume’s own guidance points at two causes: the Hume app needs permission to write data to the platform, and data typically syncs only after being processed in the Hume app — so a reading can take a while to appear. If a metric has no platform equivalent, it stays in Hume.
Does the Hume Health integration work on both iOS and Android?
Yes. Hume writes to Apple Health on iOS, and Health Connect support is confirmed live on Android, so the same Band metrics reach Sahha on either platform. Your users’ other Apple Health and Health Connect sources still flow through the same Sahha SDK.
Is the Hume Health integration HIPAA and GDPR compliant?
Yes. Sahha is HIPAA and GDPR compliant and SOC 2 certified, and Hume Health 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.
