You use the Libre by wearing a sensor on your upper arm. It’s a flash system, which means you wave an accompanying monitor above the sensor in order to get your glucose readings. You can repeat the process as often as you’d like.

To keep the Libre system working, you have to reapply a new sensor to your arm every 14 days. 

One downside to this CGM is that it can be a little confusing to keep track of their latest models that have the same names.

The FreeStyle Libre 3, which received FDA clearance in May 2022, offers automatic alarms and regular monitoring without the need for self-scans.
