FreeStyle LibreLink – GB

FreeStyle LibreLink is a companion app for FreeStyle Libre and Libre 2 sensors. It lets you scan your sensor with your phone to view your current glucose reading, trend arrows, and history. With Libre 2, readings update automatically every minute and alarms alert you to low or high glucose. You can also access reports like Time in Range and Daily Patterns and share your data with your doctor or family with permission.

The app supports starting the sensor from either the phone or the Libre 2 reader to receive alarms, and data from multiple devices can be uploaded to LibreView for a complete view. Compatibility varies by device, so check the official FreeStyle Libre site for supported phones and OS versions.
