When using the FreeStyle Libre 3 app* the user must have access to a blood glucose meter because the app does not provide one. When the app displays the Check Blood Glucose symbol, a fingerstick is required for treatment decisions. Fingersticks are also required 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.
* The FreeStyle Libre 3 app is only compatible with certain mobile devices and operating systems. Please check our compatibility guide for more information about device compatibility before using the app.
