This is the introduction screen on an iPhone.  This screen will contain your store name and identifying artwork.  In this case, we're showing the logo of our demo store, Freshest Fruit.

This is the categories list on Windows Mobile.  We will arrange the categories in a manner that best presents your products.  We use touch and gesture based navigation throughout the application.  Additionally, the menu bar at the bottom of the screen can be used to quickly switch from one screen to another.  

This is a list of products inside a category.  The user can get here just by touching a category in the category list.

The product detail page is where the user can see all of the details about their chosen product.  If they choose, then can add the product to the cart and make additional choices such as size or color. 

This is the cart.  Like a website cart, it shows the user what items have been added and allows them to change quantity or remove the item depending on their wishes.

This is the search screen.  This will help the user find a product quickly by allowing them to find an item by attribute or description.

This is the about screen.  This text describes your Mobile Store App and gives them guidance on using it more effectively.
