Apple\'s 10 changes under Tim Cook, from Apple Watch health checks to iPhone payments

After Tim Cook became Apple CEO, Apple broadened the roles of existing devices rather than simply adding new products. The Apple Watch shifted toward health management, AirPods added hearing and accessibility features, and the iPhone expanded into payments, identity and satellite communications. Apple runs its ecosystem on more than 2.5 billion active devices. Services grew alongside hardware, with fiscal 2025 services revenue of $109.2 billion and App Store weekly users averaging more than 850 million.
