Troubleshooting Common Issues

❓ Export takes too long or freezes

Solution: Restart iPhone and try again. Ensure you have 30%+ battery and stable performance (close other apps).

❓ Can't find export.zip file on iPhone

Solution: Check Files app → "On My iPhone" → "Downloads" folder. If using iCloud Drive, check iCloud → Downloads.

❓ File too large for email (over 25 MB)

Solution: Use iCloud Drive, Google Drive, Dropbox, or USB cable transfer instead.

❓ iPhone not recognized by Windows

Solution:

  • Install iTunes for Windows from apple.com/itunes
  • Unlock iPhone and trust the computer
  • Try different USB port or cable
  • Restart both devices

❓ GLYVIA won't import the file

Solution: Ensure you're selecting the .zip file (not the extracted folder). File must be named "export.zip" from Apple Health.

❓ How often should I update my export?

Answer: Re-export whenever you want updated reports. GLYVIA can handle multiple imports and will update your data accordingly.
