Stupidly has zero privacy. Must use the back of the phone to scan, result fills up half the screen, can read it 50 ft away. If BG is high, everyone around sees. App's functional but doesnt do any more than the reader. Activate with app, cant use reader again. Why do you need another app for auto-sharing? Ridiculous US14day can't be scanned by apps actually useful with privacy options. All the laws in the US, but theyre allowed to market a Flash GM as a CGM. It's not a CGM, by basic definition.
