Created using Proto.io library of fully interactive, native watchOS components.

This simple prototype demonstrates how have a container expand and collapse while moving adjacent content in sync.

Here's a demo showing a basic color picker using a container with 4 states for both the colored star and the color swatches.

Basic shapes like rectangles, lines, circles, text and more are available and they can be dropped on the canvas to create the very first draft of a mobile app in order to demonstrate the flow and functionality of the app.

Proto.io comes with UI libraries for iOS, Android Material Design, Windows and Apple WatchOS so that people can easily drag and drop those elements to bring their ideas to life. Simple interactions can also be applied, primarily screen-linking and basic navigation.

This prototype is a simulation of one part of the Pandora iPhone app. I have chosen to simulate the part of the app where the user selects a Pandora radio station and then proceeds to select that station. What I have demonstrated is how how the radio station animates from a small entry on a list to a large full screen entry and vice versa.
