Whether your scale was set up via Wi-Fi or Bluetooth, your data is automatically synced within a few minutes after you step down from it. Your data is then immediately accessible in the Withings Withings App.

As air quality is tracked continuously, it is recommended to sync this data regularly. If your scale was set up in Bluetooth, it is recommended to weigh in regularly to do so. If your scale was set up in Wi-Fi, air quality data is automatically synced:

• 14 hours after your last weigh-in, and then every 14 hours (default behavior)
• Once a night (if the Steps screen is activated)
