Apple's dedicated “TV” app, announced at last month's Mac event, a week ago made an appearance on iOS 10.2 beta 2. Yesterday, Apple released third developer-only betas of iOS 10.2 and tvOS 10.1 and the new TV app has replaced the stock Videos app and its accompanying widget on iOS devices.
And now, various web and Twitter reports have confirmed seeing the TV app on the Home screen of their Apple TV after updating to tvOS 10.1 beta 3.
Here's a quick visual overview of the TV app's single-interface design on the fourth-generation Apple TV along with other features like the ability to change the default function of the Siri Remote's Home button.
