The design and implementation of a mobile application for "Wszystko Co Najważniejsze" ("Everything What is the Most Important" - nationwide paper medias + Internet service) required a coherent project with an existing website and a weekly in a paper edition. The aim of the application was to provide users with an intuitive tool, enabling access to articles of many well-known authors from various fields. The effects of our work can be seen by downloading the application for smartphones with Android and iOS.
