I installed the beta profile for iOS 12 on my iPhone 8 plus. On beta 2 right now. Strikes me as another minor set of upgrades. it does seem zippy. And I am anxious for Google Maps and Waze to work on Car Play -- but that seems to be more dependent on updated apps from Google. The new measurement app is very cool. My wife needed me to measure the size of the area where our dog water bowl is, so she can buy a rubber matt, so the floor doesn't get ruined, and it worked like a charm. A potentially useful, albeit strange addition to the iPhone toolbox.
