As someone that has had heart issues, their continued improvements there will keep me a loyal customer for a very long time to come.

Its position as a health device is underrated in tech circles. As we tech savvy generations age there’s a big market there.

I have hearth issues too, and the metrics Apple provides still do not help detecting them. Not to mention that there is no improvement of their high blood pressure detection. So despite the marketing that they have the most accurate sensor, there is no real advancement here.

Relying on an Apple Watch instead of a proper medical device if you're having heart issues is, well, uh... There's a reason an Apple Watch isn't a medical device.
