The Marlabs Knowledge Shelf iPad app allows users to access documents on the go, including case studies, brochures, prototypes, marketing collaterals, articles, and white papers. The app fetches menus of document types from a centralized repository and displays them on the home page. Users can navigate subfolders and files using an explorer, view files in full screen, and return to parent folders or menus. The about page provides details on Marlabs and social media links.
