If the DayBand is not tracking your sleep, follow these detailed steps to troubleshoot the issue:

1. Sync Your Device
Ensure that your wearable device (like a fitness tracker or smartwatch) is properly synced with the DayBand app. This usually means pairing your device with your iPhone and confirming that it is actively tracking your sleep. If you're unsure how to do this, consult the user manual for your specific model or check the app’s settings.

2. Update the App
Make sure you have the latest version of the DayBand app installed on your iPhone. Go to the App Store and check for any available updates. Outdated apps may have bugs that affect functionality, including sleep tracking.

3. Check Sleep Mode Settings
Verify that sleep mode is activated on your device. Some trackers require you to manually enable sleep tracking. Look for this option in the app settings or choose the sleep mode in the behavior tagging section of your profile as necessary - learn more.

4. Re-pair Your Device
If syncing is not resolving the issue, try unpairing and then re-pairing your device with the DayBand app. This can sometimes resolve underlying connection problems. To do this, go to your phone's Bluetooth settings, forget the device, and then reconnect it through the DayBand app.

5. Restart Your Devices
Restart both your iPhone and your wearable device. Sometimes, a simple restart can clear glitches that prevent sleep tracking from functioning correctly.

6. Check Permissions
In your iPhone settings, ensure that the DayBand app has the necessary permissions to access health data. Navigate to Settings > Privacy & Security > Health and check if DayBand is enabled to read sleep data.

7. Battery Levels
Ensure your wearable has sufficient battery power. A low battery can affect performance, including sleep tracking capabilities. If necessary, charge your device fully.

8. Seek Support
If none of the above solutions work, consider reaching out to DayBand support for further assistance or check online forums where other users might share similar issues and solutions - learn more.

By following these steps, you should be able to resolve the issue with your DayBand not tracking sleep.
