Hi there! I understand you're having trouble transferring data from your Dara-1 scale to the Hume app on your iPhone running iOS 18.7. To help you best, could you tell me a bit more about what's happening? For example, does the scale connect to the app at all? Is the app getting stuck during syncing, or does the data just not show up after weighing?

Meanwhile, here are some initial steps that often resolve this kind of issue:

1. Restart your iPhone: Sometimes a simple restart helps refresh Bluetooth and app connections.
2. Check Bluetooth and Permissions: Ensure Bluetooth is enabled on your iPhone and that the Hume app has permission to access it.
3. Reconnect the Scale: In the Hume app settings, try disconnecting and then reconnecting the Dara-1 scale. This can reset the connection.
4. Restart the Scale: Remove the batteries from the scale, wait about 10 seconds, then put them back in to reboot the device.
5. Update the App: Make sure your Hume app is updated to the latest version, as updates often fix syncing bugs.

If you have already tried these, please let me know exactly what steps you have taken and what you observed. That will help me provide more tailored guidance.

Are you able to see the scale in your iPhone's Bluetooth settings when pairing? Also, do other Bluetooth devices connect fine to your phone?
