my workaround for glucose watch monitoring is an android app called gluroo. if you’re using an app that sends your glucose data to a server gluroo pulls that data from the server and displays it on your watch as a specific watchface so the info that’s displayed is as accurate as the sensor you’re currently using. the downside is that gluroo can’t pull directly from whatever app you happen to be using, so going to an area with no data service at all will show no stats even though your phone is right there.
vulture capitalism at it’s best. and when I say best I mean the absolute worst.
