Software as a Medical Device has been a regulated "thing" for years now, and in this case the Abbott Freestyle app is a mandatory requirement for the CGM To function. If the app can't connect to the CGM, the thing will make your phone beep incessantly. Similarly, if your blood glucose levels exceed "safe" thresholds, it will alert at full volume in a way you are not allowed to override. Frankly, this is as it should be, but it does indeed convolute things when the device interface (phone) is used for so much more, too.
