Your device data is synced with the app to reflect regular daily measurements. Real-time data is designed to temporarily display the vital data that is currently being measured. When you open the app, you can instantly check the current data. Please note that, depending on your network connection, it may take up to 20 seconds for the data to display. Please avoid closing the app while 'Sending data to the server' is displayed. Closing the app during sync may result in incomplete data reflection. Sleep data displayed on the HOME screen shows previous night's sleep. Please be aware that the data resets at noon (12:00 PM). Sync is required to retrieve the energy accumulated for daily goals completion. Please be aware that after midnight, the energy retrieval deadline passes, and you will no longer be able to acquire energy.
