What is Bulk Sync?
Bulk sync is a feature that allows you to upload large amounts of historical weight data from Apple Health to Garmin Connect all at once, rather than syncing entries one by one.
Perfect for:
- New WeightSyncr users who want their complete weight history in Garmin Connect
- Existing users who previously didn't sync historical data
- Users switching platforms who have years of data to migrate
- Data restoration after reconnecting accounts
Note: Bulk sync processes data in batches to avoid overwhelming Garmin's servers. Large datasets may take several minutes to complete.
Prerequisites
Before using bulk sync, make sure you have:
- WeightSyncr app installed and set up
- Garmin Connect account connected in WeightSyncr
- Historical weight data available in Apple Health
- Stable internet connection for the sync process
Verify Your Historical Data
- Open the Apple Health app
- Tap Browse > Body Measurements > Weight
- Check that you have weight entries going back to your desired start date
- Note the date range you want to sync
How to Bulk Sync
Step 1: Access Bulk Sync Feature
- Open WeightSyncr
- Go to the Settings tab
- Look for "Sync Past Entries" or "Bulk Sync"
- Tap on the bulk sync option
Step 2: Choose Date Range
- Select your start date (how far back to sync)
- Choose your end date (typically today's date)
- Review the estimated number of entries to be synced
Tip: Start with a smaller date range (e.g., 1-3 months) for your first bulk sync to test the process.
Step 3: Start the Bulk Sync
- Review your settings

Monitoring Progress
During Bulk Sync
- Progress bar: Shows percentage completed
- Entry counter: Displays "X of Y entries synced"
- Status messages: Real-time updates on the process
- Estimated time: Remaining time for completion
What to Expect
- Processing time: 1-10 seconds per weight entry
- Batch processing: Entries are uploaded in groups
- Automatic pausing: Brief pauses between batches
- Error handling: Failed entries are retried automatically
Important: Keep your iPhone screen on and WeightSyncr active during bulk sync to prevent interruption.
Troubleshooting
Bulk Sync Stops or Fails
- Check internet connection: Ensure stable WiFi or cellular
- Restart the app: Close and reopen WeightSyncr
- Verify Garmin connection: Check Settings tab for "Connected" status
- Try smaller date range: Reduce the number of entries per batch
Some Entries Missing in Garmin Connect
- Check sync summary: Review which entries succeeded/failed
- Retry failed entries: Use the retry function if available
- Manual sync: Sync individual missed entries from the Home tab
- Date conflicts: Garmin may reject entries with identical timestamps
Process Takes Too Long
- Normal for large datasets: 1000+ entries can take 30+ minutes
- Check progress regularly: Ensure the process is still active
- Split into smaller batches: Sync 3-6 months at a time
- Background processing: Let the app run in foreground
Frequently Asked Questions
How far back can I bulk sync?
You can sync as far back as you have data in Apple Health. WeightSyncr will sync all available weight entries in your selected date range.
Will this create duplicates in Garmin Connect?
WeightSyncr attempts to avoid duplicates, but some may occur if you have multiple entries for the same date and time. Review your Garmin Connect data after bulk sync and remove any duplicates manually if needed.
Can I use my phone during bulk sync?
It's best to keep WeightSyncr active and avoid switching to other apps during the bulk sync process. You can use your phone for other tasks, but return to WeightSyncr periodically to ensure the process continues.
What happens if bulk sync is interrupted?
WeightSyncr will remember where it left off. When you restart the bulk sync, it will continue from the last successfully synced entry, not start over from the beginning.
Is bulk sync free?
Bulk sync availability depends on your subscription status. Check our pricing options for current feature availability.
How often should I use bulk sync?
Bulk sync is typically used once to import historical data when first setting up WeightSyncr. After that, regular automatic or manual syncing handles new entries as they're created.
