The document summarizes the challenge, approach, and results of designing apps for the Microsoft TechDays Belux 2013 event for Windows 8 and Windows Phone with limited time. The approach involved benchmarking other Techdays apps, breaking down essential functionalities, sketching structure, and user interviews. The Windows 8 app featured a fixed column for communication, background image for emotion, custom agendas, and multiple entry points. The Windows Phone app focused on consistency with Windows 8 design and bringing custom agendas to the front using Windows Phone patterns. Screenshots showed the Windows 8 hub, program section, and snap views as well as the Windows Phone app.
