Greg showed off his focus modes an I agree that while they're a bit confusing to set up they're excellent. I'm almost always in a focus mode that only lets my wife and daughter get through.
Sure I want to message with friends about bikes and stuff, just not during my workday or in the evenings when I could be spending time with my family. Focus Mode has made my phone time more intentional. I spend more time with those I live with doing things that I value instead of on middling goals.
