FreeStyle Libre 3 Plus vs. Libre 3
One of the primary differences between FreeStyle Libre 3 Plus and the original Libre 3 is sensor wear duration.
Libre 3 Plus is designed for up to 15 days of wear, while Libre 3 is designed for up to 14 days.
Compatibility can also differ between Libre generations and connected devices. Customers transitioning from Libre 3 to Libre 3 Plus should verify compatibility with their current reader, smartphone and any connected insulin-delivery system.

- Optional high and low glucose alarms
- Compatibility with supported readers and smartphones
Libre 2 vs. Libre 3
FreeStyle Libre 2 and Libre 3 belong to different generations of Abbott's FreeStyle Libre CGM family.
Libre 3 uses a smaller sensor and automatically sends glucose readings to a compatible smartphone or display device. Libre 2 operates differently depending on the compatible device and system configuration.
Newer Plus versions of both systems also offer longer sensor wear than the original versions.
Customers should not assume that sensors, readers or other components are interchangeable between Libre generations.
Which FreeStyle Libre Sensor Do I Need?
The appropriate sensor depends on the FreeStyle Libre system you currently use and the devices you use with it.
Before ordering, check the exact product name of your current Libre sensor and verify compatibility with your reader, smartphone, insulin-delivery system or other connected device.
