The FreeStyle Libre 3 is more than just tech; it’s a valuable ally in managing childhood diabetes. Once the ultra-compact sensor is placed on the body, it actively monitors glucose levels and sends this crucial data straight to a paired smartphone. After a 60-minute setup post-application, both you and your child can instantly see glucose readings on your smartphone. Added to this, real-time alerts provide a heads-up if glucose levels move out of the desired range.
