Getting Started

Connecting to Health Connect (Android)

Set up Sunu on Android with Google Health Connect so your Fitbit, Galaxy Watch, and other wearables sync automatically.

On Android, Sunu uses Google Health Connect to sync health data from your wearables and fitness apps. Health Connect is the unified health data hub on Android, supported by Samsung Health, Fitbit, Garmin, Google Fit, and many other apps.

Before You Start

Health Connect is built into Android 14 and later. On older versions of Android, you may need to install Health Connect from the Google Play Store:

Health Connect on Google Play

You'll also need at least one source of health data — for example Samsung Health, Fitbit, Garmin Connect, or Google Fit — connected to Health Connect.

Connecting Sunu to Health Connect

When you first open Sunu, the onboarding flow will prompt you to grant Health Connect permissions.

Step 1: Tap Connect to Health Connect during onboarding (or Profile → Health Connection later)

Step 2: Android will open a permissions screen showing every data type Sunu is requesting

Step 3: Tap Allow all for the smoothest experience, or pick specific data types to share

Step 4: Tap Done to return to Sunu

Your data will start syncing immediately. It may take a few minutes for historical data to appear.

Managing Health Connect Permissions

You can change which data Sunu has access to at any time:

Step 1: Open the Health Connect app (or go to Settings → Apps → Health Connect)

Step 2: Tap App permissions → Sunu

Step 3: Toggle data types on or off individually

Sunu will re-sync based on the new permission set.

Supported Data Types

Sunu reads the following data types from Health Connect:

Steps, active calories, distance, floors climbed
Heart rate, resting heart rate, HRV
Blood pressure, oxygen saturation, respiratory rate
Sleep sessions and stages
Workouts (all exercise types)
Weight, height, body fat, BMI
Hydration

Any data from a wearable or app connected to Health Connect becomes visible to Sunu once permissions are granted.

Troubleshooting

Data is missing or not syncing

Open Sunu and pull down on the Home tab to trigger a manual refresh
Confirm the source app (Samsung Health, Fitbit, etc.) is actively syncing to Health Connect
Check that Sunu has permission for the specific data type in Health Connect settings
Make sure the source app is running in the background and not battery-optimized out of syncing

Permissions screen doesn't appear

If Android doesn't prompt for Health Connect permissions:

Open the Health Connect app directly
Tap App permissions
Find Sunu in the list and tap to grant access manually

"Health Connect not available"

On older Android versions, you may need to install Health Connect from the Play Store. Android 14+ has it built in.

Clinical Records (Medical Records)

Clinical health records (FHIR-formatted medical records) are currently only available on iOS through Apple Health. Health Connect does not yet support FHIR medical records. You can still add medications, conditions, supplements, and allergies manually in the Sunu app.

🔋 Battery Tip

If syncing stops unexpectedly, check your Android battery settings. Some manufacturers aggressively battery-optimize background apps, which can prevent Health Connect from updating. Exempt your wearable's companion app and Health Connect from battery optimization for reliable syncing.
