Yeah, Medtronic is a bunch of assholes for things like that. If you really wanna rage, look at how the company does everything they can to not allow communication between blood sugar live sensors and pump controllers. Biomedical enthusiasts (I loathe the term biohacker) have been working this idea with older, more easily hackable pumps.

This particular pump requires it because its a wearable with no interface. There are still some that have a drip line and cannula, but, I dunno about their interface, they very well may require a phone too. The Omnipod system does come with a "free phone". It's some no-name Motorola that's about twice as thick as a regular phone. I don't really want to carry it, my personal phone, and my work phone, way too much junk. Before smartphones, the pump was the interface, a small screen, a few buttons and AA battery powered. They were OK, but had several downsides. The drip line being the biggest for me, it was always getting caught on stuff.

That is the app, but I've only ever downloaded it from the play store, even on graphene, here's their "official stance" it's funny that they ship a Motorola device with the first set of kits so you'll have a compatible device, but those aren't natively compatible. I haven't tried through an emulator, but can give that a go. I'll also fire up the graphene phone later and get it's exact error.
