With the launch of watchOS 7, Apple has announced a new feature called Family Setup which will allow Apple Watch to be setup and configured for kids and older adults without an iPhone. Parents will be able to setup restrictions on who their kids can communicate with, access their location, and even setup Activity goals for them to keep them motivated.

The purpose behind Family Setup is to help users without an iPhone to take full advantage of the features that an Apple Watch offers such as health and activity tracking, communication, maps, Apple Pay, and emergency SOS. Using their iPhone, parents will be able to pair and configure the Apple Watch for various family members.
