Apple Health Import on iPhone: What Rizin Syncs
By Rizin AI Team · May 14, 2026 · 4 min read · Product Update
Connect Apple Health on iPhone to opt in to read-only import of steps, active calories, and workout records for average workout heart rate.
Availability: Rizin's iPhone app is available on the App Store and supports optional, read-only Apple Health import after you tap Connect. It imports steps and active calories and reads workout records to calculate average workout heart rate. This is an iPhone feature, not a standalone Apple Watch app.
Optional Apple Health activity data
After you choose Connect Apple Health and approve access in iOS, Rizin can read your steps, active calories, and workout records. The connection is read-only: Rizin does not write data to Apple Health.
What Rizin imports
- Steps — an aggregated step count.
- Active calories — aggregated active energy.
- Average workout heart rate — Rizin reads workout records and associated heart-rate samples to calculate an average. It does not sync or store workout-session details.
Sleep and HRV are not imported. You can manage or revoke Apple Health permission in your device settings.
How imported values appear
The app can show your steps, active calories, and average workout heart rate as activity information. Workout-session details are not imported or saved.
Apple Health data is not described as an automatic workout-plan or recovery adjustment. You can review these values alongside your other activity information.
How to connect on iPhone
Open Rizin on your iPhone and tap Connect Apple Health to start the optional connection. Rizin requests permission only after that action, and you choose whether to grant access. You can disconnect or change permissions in Apple Health settings.
Why this matters
The optional connection provides a convenient way to review selected activity values in Rizin. It does not sync full workout sessions, sleep, or HRV, and there is no standalone Apple Watch app.
Imported Apple Health values do not automatically change your training plan or provide medical guidance.
