A LibreView^₼ account is optional when using the Libre 3 app^◊◊. A LibreView account is recommended as it allows users to share their glucose information with their healthcare team, family, and friends, in addition to transferring their account information if they replace their smartphone.

₼ The LibreView data management software is intended for use by both patients and healthcare professionals to assist people with diabetes and their healthcare professionals in the review, analysis and evaluation of historical glucose device data to support effective diabetes management. The LibreView software is not intended to provide treatment decisions or to be used as a substitute for professional healthcare advice.

◊◊ 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.
