Hi there! I see that you’re having some trouble with the Hume Health app not tracking your sleep accurately. To help you better, could you please tell me if you are using the Hume Band or the Body Pod with it? Also, when did you start noticing this issue—is it recent or has it been ongoing for a while?

In the meantime, here are some helpful steps you can try to improve sleep tracking accuracy on iOS 18.7 with your iPhone:

1. Check Device Fit and Wear Time: Make sure your Hume Band or Body Pod is worn snugly and consistently during your sleep time.

2. Charge Fully Before Sleep: A low battery can sometimes disrupt tracking. Ensure the device is fully charged before bedtime.

3. Update the Hume Health App: Verify that the app on your iPhone is updated to the latest version from the App Store.

4. Sync Your Device Correctly: Open the app after waking and manually sync your device to avoid missing sleep segments.

5. Restart Devices: Sometimes simply restarting your iPhone and re-pairing the Hume device helps resolve glitches.

6. Allow App Permissions on iPhone: Double-check that the app has all the necessary permissions — especially for Health data, background refresh, and Bluetooth access.

7. Give It Some Time: Per some user reports, the Hume device and app may take a couple of weeks to fully calibrate and provide accurate sleep data3.

If you’ve done some or all of these already, or if sleep data is missing large chunks consistently, we may want to explore deeper steps such as reinstalling the app, checking for firmware updates on the band, or verifying if there are any server sync issues.

Could you let me know which of these steps you've tried so far, and if possible, if you notice any specific patterns (like certain nights missing data or inaccurate durations)? That way, I can better tailor the next suggestions for you!
