The primary functionality of the Apple Watch is deeply integrated with the iOS ecosystem. Its design and software framework are built to operate in conjunction with an iPhone, creating a seamless user experience centered around Apple’s proprietary technologies.
This close integration means that an Android phone cannot natively support an Apple Watch. The Apple Watch relies on specific communication protocols and services provided by iOS, such as iCloud integration, Handoff features, and the Watch app, which are absent in the Android operating system. These elements are crucial for setup, data synchronization, and overall management of the device.
