Freestyle Libre 3 vs. Dexcom G7 15 Day

FreeStyle Libre 3 is a continuous glucose monitoring (CGM) system that you wear on your skin. It's designed to replace fingersticks for people ages 4 years and older with diabetes. It measures your glucose level every minute throughout the day to better help you manage your blood sugar. The FreeStyle Libre 3 system uses a sensor that's attached to your skin, which can be scanned and read using an app on a smart device (e.g., smartphone). It doesn't include a reader, and it's important to check phone compatibility to make sure the FreeStyle Libre 3 app will work properly.
