Just a month after picking up HopStop, Apple bought one of the subway app's rivals. Embark has become a major player in the world of travel apps ever since it launched for iOS, and won the MTA's "App Quest" contest in 2012. While HopStop offers a worldwide index of subway routes, Embark takes a more personalized local approach by offering 10 separate, free apps for major U.S. cities such as New York City and San Francisco
Apple more than likely picked up Embark for the same reasons it purchased HopStop. The current version of iOS Maps sends users to external apps like Embark and HopStop when transit directions are requested, but Apple could seamlessly integrate these services into a future version of Maps with the help of these new acquisitions.
