When planning your Windows Store app, think less about what features you want to include and more about what your app is great at. Once you
define the vision for your app, you can start to
envision the possibilities for your app’s design. Think about the aspects of an app that make it unique, and
uniquely Windows. Plan how you can use
visual elements to make your app stand out from the rest. Get inspired by case studies, idea books, and examples of great app design. Plan ahead for different
form factors and
input interactions, and familiarize yourself with the
guidelines for designing the app experience.
Envision and design your app:
Defining vision helps you frame your design work around a single experience goal for your app. Decide what your app is great at and focus your thinking around that vision of greatness.
