That's fine for many applications, but for someone like me who has a Continuous Glucose Monitor having my phone/watch be with me at all times is a fact of life. I look forward to the day when my CGM interfaces directly with my watch so I don't have to carry the phone all the time.

> but for someone like me

Of course that's a special case which doesn't apply to most people. But also, why can't the CGM just have its own display, which would simplify things a lot more and likely also require much less power if it used e.g. eInk?

It sounds ridiculous to me that a medical-grade device should depend on a second consumer-grade device to be useful. If it's an added feature for e.g. logging or monitoring or telemetry to the doctors, great, I understand, but if you're just trying to get a glucose reading I strongly believe in one device giving you that reading instead of "Hey I'm a device that your health insurance paid $1000 for but sorry I'm too lame to display data and you're going to need to install this silly iPhone app to actually read its values"

"and oh by the way we also will track your contacts, which apps you are using, your GPS, and serve you and your contacts targeted ads for glucose-free health foods from our partners at Amazon"

So I can check my blood sugar without taking my shirt off.

I'd settle for it just displaying on the lock screen, so I don't need to unlock my phone and check the statuses to see what my blood sugar is at. That being said, just being able to look to see what my blood sugar is at without having to poke a hole in my finger was a massive change in how I managed my blood sugar. Having alerts for low (or dropping) blood sugar is a great thing, too. Man, I love my CGM (Dexcom G6)... can't say enough good things about it compared to manual blood testing.
