How It Works

From Apple Health to your product

1

Connect

The athlete authorizes access via Apple Health's own OAuth flow — no credentials touch your servers.

2

Normalize

Rabts maps Apple Health's data into the same unified schema used across every other provider — consistent units, consistent field names.

3

Access

Query it through the unified REST API, or subscribe to webhooks for real-time updates as new data arrives.

Notes & Limitations

What to know about Apple Health

  • Push-based via the SDK — no OAuth, since HealthKit data lives on-device until the user's app syncs it.
  • The broadest single-provider metric coverage Rabts supports (100+ HealthKit record types).
  • HRV is measured as SDNN, not RMSSD — the two aren't directly comparable across providers.
  • Some walking-biomechanics metrics require the iPhone to be carried in a pocket during the activity — an Apple platform constraint.
  • Sleep biometrics (heart rate, HRV, SpO2 during sleep) aren't yet extracted as part of the sleep record itself.
Example

Query Apple Health data through one API

FAQ

Apple Health integration questions

Do I need Apple's approval to use HealthKit data?

You need standard HealthKit entitlements in your iOS app, same as any HealthKit integration — Rabts' SDK handles the sync and normalization from there.

Is Apple Health data real-time?

It arrives whenever the user's app syncs with HealthKit — typically on app open or in the background, not via server push.
