Wearable health tech might be Tim Cook’s greatest legacy

Tim Cook’s defining Apple legacy is the Apple Watch, which helped turn wearables into a mainstream health-tech platform.

The watch expanded beyond fitness into heart-rhythm detection, fall and crash alerts, and other screening features.

Apple also used its device and Research app to support large-scale studies, making consumer wearables useful for medical research.

That shift pushed the broader industry toward health-focused smartwatches, rings, and FDA-cleared screening tools.
