Identical schema across 500+ sources
Your users connect Tally. Sahha does the rest.
This is your user’s side of the story — one screen, once. Sahha ingests every Tally 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
Tally 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 — Tally today, a new watch next year — flows through the same SDK with no extra prompt and no new code.
What Tally 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
Tally, Apple Watch, and Oura all return the same fields and units.
What crosses the bridge
Each match as a racquet sports workout pass through the platform; some device-exclusive metrics may not.

]Tally is a small independent racquet-sports app (tally.fast) — unrelated to the longevity company Tally Health. What crosses is the workout envelope: every match writes as a Racquet Sports workout, so you get the session and its duration. Match statistics — scores, rallies, and the rest of the tracking — stay in Tally and don’t reach either platform.

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 Tally developer account needed — Sahha reads what Tally 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.

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 Tally 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 Tally data the same day they add the SDK. The only per-source prerequisite: your user has Tally’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.
Tally integration questions
How does Sahha get Tally data?
Tally syncs every match to Apple Health and Google Health Connect, and Sahha reads it from there with its mobile SDK, delivering it as a normalized exercise session — no Tally API to integrate.
What Tally data does Sahha receive?
The workout envelope only. Every match writes as a Racquet Sports workout, so you get the session and its duration. Scores, rallies, and the rest of the match statistics stay in Tally.
Is this the same Tally as Tally Health?
No. This is Tally, the racquet-sports match tracker — a small independent app. It has no connection to Tally Health, the longevity and biological-age company.
Does the Tally integration work on both iOS and Android?
Yes. Tally syncs every match to both Apple Health and Google Health Connect, so the workout reaches Sahha on either platform. Your users’ other Apple Health and Health Connect sources still flow through the same Sahha SDK.
Is the Tally integration HIPAA and GDPR compliant?
Yes. Sahha is HIPAA and GDPR compliant and SOC 2 certified, and Tally 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.
