FLwatch displays blood glucose readings from Abbott FreeStyle Libre 2, Libre 3 and Libre 3+ sensors, as well as Dexcom G6 / G7 / ONE+ sensors, on your iPhone and Apple Watch.
Glucose data can be received through the LibreLinkUp cloud, Dexcom Share, or a direct Bluetooth connection to Libre 3 and Libre 3+ sensors.
Workout mode is available with every supported CGM provider. Follow your glucose graph during exercise and set a workout-specific low-glucose alert to help you notice when your glucose falls.
With Libre 3 and Libre 3+, direct-to-watch Bluetooth support lets you leave your iPhone behind during exercise. Start a workout in FLwatch to receive sensor readings directly on your Apple Watch.
Record insulin doses and view insulin-on-board and insulin activity graphs.
With Apple Watch support, widgets, Live Activities, and configurable glucose and sensor alerts, your glucose data is easily accessible across your Apple devices.
FLwatch is free and open source.
