For OBI , we have created an online version of their 2012 spring catalog. The catalog features about 1 500 products . The application enables customers to use a functional menu , browse through the whole catalog or search or particular products (it gives hints while typing). Selected products can be saved on the printable shopping list . Users can select the nearest store and add the information about its opening hours and localization to the shopping list. The catalog has also been prepared in a mobile version for the iOS system (iPad, iPhone).
