Unfortunately, they don’t have the app set up for the 670g (I think it’ll be released with later iterations)! I thought this would be a HUGE con for me, because I always tracked my sugars on my phone and Apple Watch, but I actually completely forgot about it until you mentioned it! Haha!
It’s great that the pump and CGM talk to each other, but that also means that if you want consistent readings and to stay in auto mode, you’ll need to have the transmitter and pump close enough together to continue their conversation. Not a huge deal if you work out at home, but if you do the gym, you’ll need to have your pump with you. You can always clip it to an arm band, your pants, etc. or put it in your sports bra (that’s what I do).
Something else worth disclosing, since you’re doing all of your own research here (what are doctors for, really?), is that while they do talk to each other, when you go to give yourself a bolus, the CGM reading isn’t automatically entered in the BG field. So you’ll have to either test or manually enter your CGM reading when you go to bolus (although Medtronic obviously does not condone the latter). I get lazy sometimes and don’t enter a BG at all and just enter the carbs I’ll be consuming. I’m assuming the pump then doses as if you were at 100? Whatever the algorithm is, it works fine for me!
