By contrast, the HomePod is essentially an extension of the iPhone, like an accessory. When someone asks the HomePod to open a third-party app, the request wonât go directly to the cloud, as with the Echo, but to an iPhone. As a result, developers can't write apps for the HomePod.

Macropods are marsupials belonging to the family Macropodidae, the kangaroo family, which includes kangaroos, wallabies, tree-kangaroos, pademelons, quokkas, and several others. Macropods are native to the Australian continent (the mainland, Tasmania, New Guinea and nearby islands). Before European settlement of Australia, about 65 species of macropods existed. Six species have since become extinct and a further eleven have been greatly reduced in numbers.
