The Apple ecosystem is a term used to describe Apple Inc.'s digital ecosystem of products, including the iPhone, iPad, Apple Watch, HomePod etc. It is often praised for its seamless integration and optimization between various networks of devices, software and services, and is largely emphasized by Apple's focus on privacy. It is also known for its ability to lock users into the network where it is difficult to escape.
Apple's various networks and platforms of interactive hardware and devices are described as an ecosystem due to how seamlessly they simultaneously function together with and take advantage of each other. Apple products often come with extra features when paired with other Apple products, as opposed to alternatives. Privacy is also considered a major perk of the ecosystem, as Apple markets its products with high standards of privacy, sometimes using it as a selling point over competitors.

Apple's ecosystem is often described as a walled garden. While peripherals such as AirPods, HomePods and AirTags integrate complementarily into the ecosystem, with products such as the iPhone, it does not function as well or with as many features with competitive devices such as Android smartphones. It is also not easy to switch from the ecosystem once you have immersed yourself into it, as it is designed to keep users from leaving.
