Philips Hue smart light users got a nice surprise Tuesday morning with a big update to the Hue controller app for the iPhone. Hue 3.0 sports a new interface that’s easier to use, controls for individual lights instead of just groups, an improved color picker, new scenes, the ability to use the art in a room to create light scenes, and more. The Hue 3.0 app is a free download at Apple’s App Store.
