Remember how, if you wanted to measure distance between two places, you’d have to either a) spend the next half hour searching the App Store for a non-hideous free app that wouldn’t be too frustrating to use, or b) contrive to force Apple or Google Maps to give you more-or-less direct directions between two points?
Those dark days are over, because now Google Maps on iOS has distance measuring built in. Now you can finally see how far it it from here to there. And back again, if you like.
