FDA has approved Abbott's device for measuring sugar levels in diabetic patients. The FreeStyle Libre 3 is designed for continuous bi-weekly glucose monitoring and is the smallest and thinnest in its class. FreeStyle Libre 3 can also be used with the iOS and Android mobile apps of the same name, which allow you to monitor your levels in real time, track history of changes, and set alerts and various notifications. The device will go on sale later this year.
