No, after your FreeStyle Libre 3 sensor or FreeStyle Libre 3 Plus sensor is paired with your smartphone, you will automatically see the latest glucose information when you open the Libre app† or when you receive an alarm* notification on your compatible smartphone.
† The FreeStyle Libre systems are only compatible with certain mobile devices and operating systems. Please check the Support section of our website for more information about device compatibility before using the apps. Use of the FreeStyle Libre systems apps may require registration with LibreView.
