At the end of each sleep session, your sleep analysis data should automatically be synchronized to your iPhone. Pillow relies on Bluetooth and/or Wi-Fi to exchange data between your Apple Watch and iPhone, so make sure both are enabled and the devices are within 10 meters of each other.
In case synchronization fails, please follow these recommendations:
Make sure you have installed the latest version of iOS, watchOS, and Pillow
This ensures that you are running the most current versions of all software components that could be responsible for the issue.
Make sure your devices are properly connected with each other
If you have enabled Airplane Mode or disabled Bluetooth or Wi-Fi, automatic synchronization will not work. Also confirm that both devices are close enough to maintain a stable connection.
Restart your devices
In most cases, miscommunication between devices can be resolved by restarting both your Apple Watch and your iPhone.
Additional Recommendation
When you use Pillow on the Apple Watch and the iPhone together (for alarms or audio recordings), it is strongly recommended to start and stop the sleep session from the Apple Watch.
If the problem persists, please contact our support team and we will be happy to assist you further.
