The FreeStyle Libre 2 is a system of continuous glucose monitoring (CGM) developed by Abbott, for people with diabetes. Unlike traditional glucometers, which require finger pricks to measure blood glucose, this system has a compact, circular sensor that attaches to the skin, usually on the back of the arm.
What is the FreeStyle Libre 2?
The system is composed of two main elements:
-
FreeStyle Libre 2 sensor: It continuously measures glucose levels in the interstitial fluid.
-
It is applied to the skin with an applicator and can be used for up to 14 days.
-
It features technology NFC (Near Field Communication) to scan glucose levels with a receiver or a compatible mobile device.
-
It has optional alerts to detect high or low glucose levels via Bluetooth.
-
FreeStyle Libre 2 app or reader: It allows scanning the sensor to obtain real-time glucose readings.
-
It shows trends and graphs of glucose levels over time.
-
It can be synchronized with compatible mobile devices for more convenient and faster monitoring.
This system is a more comfortable and accurate alternative for diabetes management. It allows you to know glucose levels at any time without the need for constant finger pricks and improves users' quality of life.
Importance of mobile compatibility with FreeStyle Libre 2
The FreeStyle Libre 2 app is designed to work on mobile devices that meet certain technical requirements.

The FreeStyle Libre 2 system allows people with diabetes to continuously and in real time monitor their glucose levels. To make the most of its features, it is essential to use a mobile compatible with FreeStyle Libre 2.
