If your VeryFit app has not synced sleep data for the last 5 days, follow these steps to resolve the issue:

1. Check Bluetooth and Device Connection
- Ensure your smartwatch is within close proximity to your phone and that Bluetooth is enabled and working properly. Any obstruction, like metal objects or body interference, can weaken the Bluetooth signal2.

2. Restart Devices
- Restart both your smartwatch and your phone to refresh the connection2.

3. Update the VeryFit App
- Make sure the VeryFit app is updated to the latest version. Outdated apps can cause syncing issues2.

4. Revoke and Re-enable Permissions (for Apple Health users)
- If you are syncing with Apple Health, go to your Apple Health settings and revoke VeryFit app’s write permissions, then re-enable them. This often forces a re-sync between the app and Apple Health and has resolved similar issues for other users1.

> "Go into apple health select your profile go to apps and... revoke Veryfit app write permissions for all data, after that... enable veryfit app write permissions. Nearly instantly the two apps relinked and synced data for the first time in a week."1

5. Force Sync
- Open the VeryFit app and manually initiate a sync by pulling down on the data screen or using the "Sync" button if available. Sometimes, syncing twice in a row can help update the sleep data if there’s a delay3.

6. Verify Sleep Tracking Is Enabled
- In your VeryFit app settings, confirm that sleep tracking is enabled and properly configured4.

7. Ensure Regular Synchronization
- The VeryFit watch stores sleep data for only the last 7 days, so data will be lost if not synced within that window2.

8. Unpair and Re-pair Your Device
- If issues persist, unpair your smartwatch from the app and reconnect it2.

9. Reinstall the App
- As a last resort, uninstall the VeryFit app and reinstall it. Note that this may delete unsynced data on the device, so use this step carefully5.

Key reminders:
- Always keep your smartwatch regularly synced (ideally daily) to avoid losing sleep data, as only the last 7 days are stored on the device itself2.
- Resetting the watch to factory settings will erase all stored data, so only do this if other steps fail2.

If problems continue, it may be a device-specific or app software issue. In such cases, contact VeryFit customer support for further assistance.

Sleep data is not working for the last 5 days. All other data is working fine.
