The App is compatible with both 10-day and 14-day Sensors. You can use the App to: * Check your glucose with a painless scan, instead of a routine fingerstick [1] * View your current glucose reading, trend arrow, and glucose history * Add notes to track your food, insulin use, and exercise * See glucose reports, including your Ambulatory Glucose Profile * Connect to healthcare professionals with LibreView [2] SMARTPHONE COMPATIBILITY Compatibility may vary between phones and operating systems. Learn more about compatible phones at http://FreeStyleLibre.us. ◆◆◆◆◆◆ USING YOUR APP AND READER WITH THE SAME SENSOR If you would like to use both the FreeStyle Libre Reader and the App with the same Sensor, you need to start the Sensor with the Reader first and then scan with your phone. 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. Learn more about FreeStyle LibreLink at http://FreeStyleLibre.us. [1] If you are using the FreeStyle LibreLink app, you must also have access to a blood glucose monitoring system as the App does not provide one. Fingersticks are required for treatment decisions when you see the Check Blood Glucose symbol, when symptoms do not match system readings, when you suspect readings may be inaccurate, or when you experience symptoms that may be due to high or low blood glucose.
