Casco Bay Lines App is an exercise of designing mobile application for an island ferry. It focuses on the design of an interactive way to enhance the user experience for people traveling between Portland and the nearest islands, such as Diamond Island, Peaks Island, Cliff Island, and others. The application includes an interactive schedule and additional information about the islands. My design solution utilizes white space. The bright blue-green gradient highlights call to action buttons in order to make the application easy to navigate.
