London Tube
Navigating the subway system is a bit like driving, one you understand the concept you can apply the idea anywhere. Similar to the NYC subway system is the London Tube. Speed walking and dodging people isn't the hard part about navigating, it's knowing where to go, where to switch, and "minding the gap." The London Tube app alleviates the first two issues so you can focus on the third. The app offers the most up-to-date and official map of the London Tube zones, works offline, offers service notifications by the minute, and more!
