Tim Millet, Apple’s vice president of platform architecture, has taken charge of the project after it was left without a dedicated head for several months, according to people with knowledge of the change, who asked not to be identified because the matter is private. The team leading the work, called the Exploratory Design Group, or XDG, was previously led by scientist Bill Athas, who died at the end of last year.
Earlier this week, the company announced updated Apple Watches with faster processors, but not much in the way of new health-related features. Over the past few years, however, it has added sensors for measuring blood oxygen and body temperature. It’s also working on a blood pressure monitor for release in the next two years. The hope for the glucose monitor is that it will eventually be compact enough to fit in the Apple Watch as well.
