No. With the FreeStyle Libre 3 System, users do not need to scan to receive a glucose reading. When the FreeStyle Libre 3 Sensors* are paired with the user's smartphone, they will automatically see the latest glucose information after they open the FreeStyle Libre 3 app^◊◊ or when they receive an alarm notification^{^} on their compatible smartphone.

* FreeStyle Libre 3 sensors refer to FreeStyle Libre 3 sensor and FreeStyle Libre 3 Plus sensor.

◊◊ The FreeStyle Libre 3 app is only compatible with certain mobile devices and operating systems. Please check our website for more information about device compatibility before using the app. Sharing of glucose data requires registration with LibreView.
