* The FreeStyle LibreLink app and the FreeStyle Libre reader have similar but not identical features. A finger prick test using a blood glucose meter is required during times of rapidly changing glucose levels when interstitial fluid glucose levels may not accurately reflect blood glucose levels or if hypoglycemia or impending hypoglycemia is reported by the FreeStyle LibreLink app or when symptoms do not match the FreeStyle LibreLink app readings.
† LibreView data can be viewed in the Safari Browser on Mac OS X Mountain Lion or higher computers and on iOS 6 or higher mobile devices. Currently, uploading of glucose data is only supported on Windows-based computers. Minimum system requirements are Windows Vista with IE10 or the latest versions of Google Chrome and Mozilla Firefox, running on a 550MHz Pentium III, 512MB DRAM, 2G Hard Drive, USB 2.0, LCD Screen with resolution of 1024x768.
‡ LibreView is not intended to be a primary glucose monitor: home users must consult their primary device(s) and consult a healthcare professional before making any medical interpretation and therapy adjustments from the information in the software, and healthcare professionals should use information in the software in conjunction with other clinical information available to them.
§ The FreeStyle Libre sensor communicates with the FreeStyle Libre reader that started it, or the FreeStyle LibreLink app that started it. If you wish to use both the reader and the app, start your sensor with the reader first, and then you can scan the sensor with your phone at any time during the sensor life. Data is not synchronized between devices, so to ensure your reports include all available data, choose one device that you will use to scan your sensor at least once every 8 hours.
¶ Users must be connected to the internet in order for their glucose data to automatically upload to LibreView.
