ExploreShanghai Metro map now an iPhone app

File this under things that can come in handy: Exploremetro (who’s intrepid founder became – we think – the first person to visit every station on the Shanghai Metro system in one day earlier this year), has an iPhone app out that details Shanghai’s underground. Besides having up-to-date info on line extentions (and free updates when the other lines are finished), the app also allows you to plan routes, communicate bilingually and access the map without internet. Fun!
