I have a scale that tells me my weight and body fat percentage, and it is able to sync directly into Apple Health. And yet, the scale isn't able to read any of my health data, including my weight! They have done a great job with Apple Health, making your data accessible and yet easy to set permissions so it's in your control.
The author mentions blood glucose monitoring, and I'm sure Apple will attempt to do that at some point. But there are so many more things they could potentially do.
How about a chest strap for workouts? I'm fascinated by how my watch measures my V̇O₂ max for me, but it seems like it would be far more accurate with more inputs.
What if Apple Watch, or some other device, could detect heart attacks? It can already detect some heartbeat irregularities.
I'm sure Apple could make an even better scale than the one I already have. My understanding is the body composition readings aren't too accurate on those things.
Imagine an Apple weight loss program: guaranteed to lose 10lbs in 2 months if you follow the instructions your watch gives you!
Here would be the real killer for me: what if Apple made glasses which could detect all the food you eat and log the calories and nutrients? I've done a fair amount of manual meal logging into apps that integrate with Apple Health, and it can be really helpful for monitoring your diet. But typing every meal into your phone isn't scalable -- I inevitably give up after a couple weeks.
One more thing: how can hospitals and doctors get access to this data? I've done some searching for a primary care physician that has the ability to integrate with Apple Health, and I haven't found any. Can Apple create a paid service that empowers service providers with more data?
I think Apple is the company that can 1) build the best, most high-tech consumer health products, and 2) sell the value of those products to the public.
Cars and AR are cool, too, but, as the author points out, consumers aren't really seeing the value in those. If Apple can make its health products even more life-changing than they already are, then someday we will live in a world where it's weird to not be monitoring your health, like it would be weird to not have a smartphone these days.
