FreeStyle Libre 2 is a mobile health app designed to work with the FreeStyle Libre 2 continuous glucose monitoring (CGM) system. Developed by Abbott, the app allows people with diabetes to track their glucose levels in real time using a small sensor worn on the body. Instead of traditional fingerstick testing throughout the day, users can simply scan the sensor with their smartphone to view current glucose readings, trends, and historical data.

The app is widely used by individuals managing diabetes who want a more convenient and less invasive way to monitor their blood sugar. By providing alerts, trends, and easy-to-read reports, FreeStyle Libre 2 helps users make informed decisions about diet, exercise, and medication. It also allows data sharing with caregivers or healthcare professionals, making it a useful tool for ongoing diabetes management.
