Ratings & Reviews

  • This app hasn’t received enough ratings or reviews to display an overview.

Made for iPhone Duo. On the inner display, Journeys and Transactions show the list beside the chosen item, and the Subway map opens station details in a side panel while the map stays in view. Propped half open, Home and the map split at the fold. Bug fixes and improvements.
