I am a type 1 diabetic. I use a Medtronic pump and CGM (continuous glucose monitor). Medtronic has a mobile app that transmits the data from the pump to the phone. Currently, you can receive the notifications from the pump to the phone to your Garmin device via the notifications. What would be really helpful to me and other people using these pumps would be a watch face that could display the glucose reading and trend information. This has been done in the past for the Night Scout Project setup.
Would anyone be interested in doing this?
