# HealthKit Integration with Open Wearables

> Integrate Apple Health via HealthKit using the Open Wearables Flutter SDK. Push-based sync for steps, heart rate, sleep, and workouts. iOS 13+ required.

## Overview

Apple Health integration uses a **push-based model** where health data is sent from the user's device to Open Wearables using our mobile SDK. This is different from cloud providers like Garmin or Polar that use webhooks.

<Note>
  **Why Push-Based?** Apple HealthKit doesn't expose a cloud API. Health data lives exclusively on the user's device, so your mobile app must actively push data to your backend using our SDK.

## Flutter SDK Quick Start

The fastest way to integrate Apple Health:

```dart theme={null}
import 'package:health_bg_sync/health_bg_sync.dart';

// 1. Configure SDK
await HealthBgSync.configure();

// 2. Sign in with credentials from your backend
await HealthBgSync.signIn(
  userId: credentials.userId,
  accessToken: credentials.accessToken,
);

// 3. Request permissions
await HealthBgSync.requestAuthorization(
  types: [
    HealthDataType.steps,
    HealthDataType.heartRate,
    HealthDataType.sleep,
  ],
);

// 4. Start background sync
await HealthBgSync.startBackgroundSync();
```

## Requirements

| Requirement             | Details                                 |
| ----------------------- | --------------------------------------- |
| iOS Version             | iOS 13.0+                               |
| Apple Developer Account | Required for HealthKit entitlement      |
| Physical Device         | HealthKit doesn't work in iOS Simulator |

## Supported Data Types

Apple Health provides the widest range of health data types:

* **Activity**: Steps, distance, flights climbed, active energy
* **Heart**: Heart rate, resting HR, HRV, VO2 max
* **Sleep**: Sleep sessions with stages
* **Workouts**: All workout types with detailed metrics
* **Body**: Weight, height, body fat percentage
* **Nutrition**: Dietary intake tracking

See the [Flutter SDK documentation](/sdk/flutter#supported-health-data-types) for the complete list of supported types.

## Apple Health as a Data Bridge

Even if a provider is **not yet directly supported** by Open Wearables, its data can still be collected by syncing it into Apple Health first.

<Warning>
  **Data scope may differ.** Third-party providers often write a limited subset of their data to Apple Health compared to what's available through their native APIs. For example, a device might expose detailed HRV metrics in its own app but only sync basic heart rate samples to HealthKit. If you need the full data scope, prefer a direct provider integration when available.
</Warning>

Apple doesn't publish an official, exhaustive list of HealthKit-compatible apps. The tables below were compiled from internet research using Claude (as of April 2026).
