# Building watchOS app Interfaces Using the Storyboard

Create the user interface for your watchOS app by nesting stacks.

## Overview

watchOS apps use a simplified, stack-based layout model for their user interfaces. Xcode automatically groups elements into horizontal and vertical stacks, and you can fine-tune the layout by modifying the element’s attributes. Additionally, you can ensure that your interface works as expected on all Apple Watch sizes by using resizable elements and size-specific customizations.

As you add items to the storyboard, Xcode stacks them vertically, with each item on its own line ([Figure 1](building_watchos_app_interfaces_using_the_storyboard.md)).

![]()

Use Groups to create horizontal or vertical stacks ([Figure 2](building_watchos_app_interfaces_using_the_storyboard.md)). Groups don’t have a default visual representation, but you can configure a background color or image as needed. Nest Groups, as necessary, to create more complex layouts.

### Customize the Layout Using Attributes

You can fine-tune an interface element’s size and layout using the Attributes inspector. All interface elements have the following attributes:

Groups provide additional options to manage their content:
