Before Google Maps offered public transit directions, HopStop was our go-to for pedestrian directions. HopStop works in over 60 cities around the world (and all major ones in the U.S.). Like the website, HopStop tells you how to get to your destination using public transportation. It offers schedules for trains and busses and even lets you mix up how you travel, allowing you to pick a mixture of walking, train, bus, or, thanks to new biking directions, bike. If public transportation is not possible, HopStop will recommend a taxi service and let you know the trip’s estimated cost.
