Identical schema across 500+ sources
Your users connect Flo. Sahha does the rest.
This is your user’s side of the story — one screen, once. Sahha ingests every Flo 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
Flo data is read on the user’s own device, only after they grant Health Connect permission — nothing syncs without consent.
One integration, every source
Permission is per data type, not per brand. Anything that writes to Health Connect — Flo today, a new watch next year — flows through the same SDK with no extra prompt and no new code.
What Flo syncs through Health Connect.
Request only what you need
You choose exactly which of these signals to request from Health Connect — users are only ever prompted for those, which keeps opt-in rates high.
One schema, every source
Flo, Apple Watch, and Oura all return the same fields and units.
What crosses the bridge
Menstrual flow, ovulation tests, and cervical mucus pass through Health Connect; some app-exclusive metrics may not.

] Flo writes cycle-tracking entries to Health Connect, which Sahha delivers as reproductive tags (event values like menstrual_flow: light) via API and webhooks. Flo syncs to Health Connect on Android; its Apple Health sync has been discontinued, so it lands in Health Connect, not Apple Health.

Get more than just raw data
Sahha turns these signals into biomarkers, scores, archetypes, and insights — the modeling done for you.
Reading Health Connect yourself? Here’s the to-do list.
Everything on the left is yours to write, test, and maintain on Android. Everything on the right, Sahha already did.
- Integrate Health Connect.
- Handle Android version differences.
- Add Apple Health separately for iOS.
One SDK covers Health Connect, Apple Health, and every cloud source.
- Write the Health Connect 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 Health Connect record types.
- Reconcile against your iOS 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.
- Google changes a Health Connect API.
- You find out in production.
We version the SDK. You never notice.
No Flo developer account needed — Sahha reads what Flo already writes to Health Connect on Android.
Live in an afternoon, not a sprint.

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

Prompt for Health Connect permissions
Call the SDK to show the native 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 Flo data from Health Connect in the background, normalizes it to one schema, and streams it to your app by webhook or API.
Most teams read live Flo data the same day they add the SDK. The only per-source prerequisite: your user has Flo’s Health Connect sync switched on — most source apps enable it by default.
Flo integration questions
How does Sahha get Flo data?
Flo writes cycle-tracking entries to Health Connect, and Sahha reads them from there with its mobile SDK, delivering them as normalized reproductive tags — no Flo API to integrate.
How is cycle data delivered — as biomarkers or tags?
As reproductive tags. Cycle entries are categorical events (menstrual_flow: light/medium/heavy, ovulation_test: negative/high/positive, cervical_mucus: dry/sticky/creamy/watery/egg_white), delivered through Sahha’s API and webhooks alongside biomarkers and scores.
Does the Flo integration work on iOS?
Sahha reads Flo through Health Connect on Android — Flo’s Apple Health sync has been discontinued. The same Sahha SDK still reads Apple Health on iOS for your other sources, all normalized to one schema.
Do I need a mobile app to use the Flo integration?
Yes. Because Flo data lands in 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 Flo do.
Is the Flo integration HIPAA and GDPR compliant?
Yes. Sahha is HIPAA and GDPR compliant and SOC 2 certified, and Flo 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.
