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

]WomanLog writes menstruation, spotting, sexual activity, basal body temperature, and weight to Apple Health, which Sahha delivers as reproductive tags and biomarkers via API and webhooks. It’s an iOS app, 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 WomanLog developer account needed — Sahha reads what WomanLog 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.

Call the SDK to show the native Apple Health 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 WomanLog 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 WomanLog data the same day they add the SDK. The only per-source prerequisite: your user has WomanLog’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.
WomanLog integration questions
How does Sahha get WomanLog data?
WomanLog writes cycle entries, basal body temperature, and weight to Apple Health, and Sahha reads them from there with its mobile SDK, delivering them as normalized tags and biomarkers — no WomanLog API to integrate.
How is cycle data delivered — as biomarkers or tags?
Cycle entries arrive as reproductive tags (menstrual_flow, intermenstrual_bleeding, sexual_activity), while basal body temperature and weight arrive as biomarkers — all through Sahha’s API and webhooks alongside scores.
Do I need a mobile app to use the WomanLog integration?
Yes. Because WomanLog 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 WomanLog do.
Is the WomanLog integration HIPAA and GDPR compliant?
Yes. Sahha is HIPAA and GDPR compliant and SOC 2 certified, and WomanLog 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.
