Apple's new HomeView does not have an app store. It borrows apps from your phone instead.
HomeView ships with Apple's own apps built in, including Apple Music, Apple Podcasts, Apple News, Calendar, FaceTime, and Messages. For everything else, it leans on a CarPlay-style setup: when a compatible iPhone or iPad is nearby, paired, and recently unlocked, HomeView displays that device's third-party audio and video apps, things like Spotify and Audible, plus iOS video apps whose developers add support. Up to six household members can be recognized by voice and the device's front-facing camera, with each person's apps and data showing only after they are enrolled and authenticated. Shared photos and music stay open to anyone in the house, including guests, but guests cannot see personal data.
This is a deliberate shortcut, not a missing feature. Building and policing a standalone app store is expensive and slow; piggybacking on CarPlay's existing developer relationships gets Apple a working app ecosystem on day one. The tradeoff is dependence: HomeView is only as useful as the iPhone sitting near it, which ties the product's value to the rest of Apple's hardware lineup rather than letting it stand alone.
It is the same bet Apple made with the Apple Watch before watchOS matured, and with the original Apple TV before tvOS got its own store. Convenient, until you are the one guest without a paired iPhone.
