How to Sync Withings Weight to Garmin Connect

Prerequisites

Before we start, make sure you have:

• A Withings scale (Body, Body+, Body Cardio, or Body Comp)
• iPhone running iOS 16.0 or later
• Withings app installed and connected to your scale
• Garmin Connect account
• Apple Health app (pre-installed on iOS)

Step 1: Set up Withings with Apple Health

If you haven't already connected your Withings scale to Apple Health, follow these steps:

1. Open the Withings app on your iPhone
2. Open its profile, connected apps, or integrations settings
3. Select Apple Health
4. Toggle on "Weight" to allow data sharing
5. Tap "Allow" when prompted

Your Withings scale should now automatically send weight measurements to Apple Health when you step on it.

Step 2: Download and configure WeightSyncr

1. Download WeightSyncr from the App Store
2. Open the app - you'll be prompted for Apple Health permissions
3. Grant Apple Health access when prompted:
   • Tap "Allow" for HealthKit access
   • Toggle ON "Weight" in the read permissions
   • Tap "Allow" in the top right
4. WeightSyncr will now have access to your weight data from Apple Health

Step 3: Connect to Garmin Connect

1. In WeightSyncr, tap the "Settings" tab
2. Tap "Connect Garmin Account"
3. Follow the prompts to authenticate with Garmin
4. Complete account verification if Garmin requests it
5. Wait for the connection to complete

Your Garmin account is now connected! You should see a green "Connected" status in the Settings tab.

Step 4: Test the sync

Let's make sure everything is working correctly:

1. Step on your Withings scale to record a new weight measurement
2. Wait for the data to appear in Apple Health (usually takes 1-2 minutes)
3. Open WeightSyncr and check the Home tab
4. You should see your new weight entry with a sync status
5. Check Garmin Connect - your weight should appear immediately

Manual sync (Free users)

If you're using the free version, you'll need to manually sync each entry:

1. Open WeightSyncr and go to the Home tab
2. Find your new weight entry
3. Tap the "Sync" button next to it
4. The entry will upload to Garmin Connect

Automatic sync (Premium users)

Premium subscribers enjoy automatic background sync:

• New weight measurements sync automatically
• No need to open the app
• Data appears in Garmin Connect immediately

Troubleshooting

Weight data not appearing in WeightSyncr

• Check Apple Health permissions: Go to Settings > Privacy & Security > Health > WeightSyncr and ensure "Weight" is enabled
• Verify Withings data: Open Apple Health and confirm your weight measurements are there
• Force refresh: Pull down on the Home tab in WeightSyncr to refresh

Sync failing to Garmin Connect

• Check connection status: Go to Settings in WeightSyncr and verify Garmin shows "Connected"
• Reconnect account: Tap "Disconnect" then "Connect Garmin Account" again
• Authentication requested: Reconnect and complete Garmin verification

Data synced incorrectly

• Check units: WeightSyncr respects your Apple Health unit preferences (lbs/kg)
• Time zones: Ensure both your iPhone and Garmin account are set to the same timezone
