My 13 year old is a type 1 diabetic. He has used an iPhone SE / mini since he was 7. He plays ice hockey and has a pouch in his hockey pants for his phone. It’s never had an issue through all the bumps that ice hockey brings.
We also use an iPhone SE for our T1 teenager. One drowned in the ocean a few years back, but other than that they've been pretty robust and reliable for us. We do Otter Box them with a screen protector.
Hopefully Apple keeps up releasing the smaller phone range. I would like to get an iPhone for my son, still a bit too big for him. Maybe when he is 7 :)
Not the OP of this thread, but for our setup the phone is just for the CGM. The pump (Tandem T-Slim) talks directly to the CGM (Dexcom G7) and doesn't need the phone as an interface between them.
The phone just sends the CGM data on to the cloud so we can see his numbers any time.
I also have a NightScout setup that's downloading his CGM data and saving it for us. It's not strictly necessary for anything we're doing, but I like the saved data and it's was useful for working with his Endo when they hadn't yet bought a Dexcom clinic license.
OmniPod pumps have both iOS and Android apps, as well as a prepackaged Android based device (without a cellular modem.)
This is an area in which technology is hugely helpful, however the development cycle is incredibly slow. Like glacial. It’s unclear how much that’s helping…
That said, I’m super happy to have the options we have at this point.
