Features & benefits

One of the key differences between the two systems is that the Freestyle Libre 3 has a built-in sensor that continuously measures glucose levels and sends the data to a reader device. On the other hand, Freestyle Libre 2 requires the user to manually scan the sensor with a reader device to obtain glucose readings.

This means that the Freestyle Libre 3 reader provides more real-time and accurate glucose readings, while the Freestyle Libre 2 may need to be more accurate and convenient.

The Freestyle Libre 3 also has a new feature called “Smart Alerts,” which sends an alert when glucose levels are predicted to reach a high or low level in the next 30 minutes. This feature is not available on the Freestyle Libre 2.
