Compatibility

For Apple TV running tvOS 17 or later. Everything is done with the Siri Remote: Select opens settings, swiping changes speed and density, and Play/Pause freezes the stars in place.Starflight keeps the Apple TV screensaver from starting while it runs. Your TV's own sleep timer is separate, so raise it in the TV's settings if you want Starflight to run for a long time.

Privacy
