During the first quarter of 2012, we have created for OBI a newsletter application. The application enables users to search for particular products(gives hints while typing) and to create printable shopping lists, which contain information about the nearest store’s address and opening hours. Users can also save selected pages of the newsletter as pdf. Browsing through the newsletter has been made very easy with the use of big pop-up windows. In our opinion, it is the most functional and optimized newsletter application on the Polish market. Our responsibility was to design the interface of the application, develop its software and its regular actualization.
