Note that FreeStyle LibreLink and Readers do not share data with each other. For complete information on a device, scan your Sensor every 8 hours with that device; otherwise, your reports will not include all your data. You can upload and view data from all of your devices on LibreView.com. APP INFORMATION FreeStyle LibreLink is intended for measuring glucose levels in people with diabetes when used with a Sensor. For more information on how to use FreeStyle LibreLink, refer to the User’s Manual, which can be accessed through the app. If you require a printed User’s Manual, contact Abbott Diabetes Care Customer Support.
