A software replacement for the physical remote that came in the box with your fourth-generation Apple TV, Apple's entirely overhauled Remote application provides you with the full range of Siri Remote features complete with touch navigation, tilt-based control in games and voice input via Siri.
And in making tedious text entry on tvOS even easier than before, the new app lets you summon the keyboard right from the Lock screen of your iPhone by pressing a notification that automatically gets pushed every time you select a text field on the Apple TV.
