Create Design for App - focus on user interface

Hi, We are currently developing and app for which we require a design. The app implements an easy access interface for a list of web services so search forms, autosuggest fields, menus, pickers etc. are the focus. The app is being developed for both iOS and Android. There are three screens: search/interface screen, result screen and history screen - Should be a clean, simple yet elegant design. - As text is a core element of the app and its functionalities, you should have a good knowledge of typography. - We only want one version for boths systems. - You still need to pay attention to the design guidelines (as much as possible): - [login to view URL] - [login to view URL] Please provide us with examples with app designs you already did. In the next step, we will provide you with screenshots and a detailed description of what the app does. Deliverable is a set of .pds files together with .png files of the screens (and variants of the screens with different menus for different systems etc.) Please let us know if you can also provide sliced versions. Cheers, Alex
