One of the biggest complaints lodged against Apple's Maps app is its lack of public transportation directions. Fortunately, there are options out there like HopStop. Covering more than 62 cities in the U.S. and abroad, Hopstop provides users with detailed public transit, taxi, biking and walking directions. The app also provides access to transit schedules, shows nearby bus and subway stops and lets you save recent searches. There are even wheelchair accessible and stroller-friendly routing options.
