I simulated a 10 second timer that counts down from 10 to 0. This is very simple to do. All you need to do is change the text property of the text value with a custom value and include a delay of 1 second. Then add a callback for the next number with a delay of 1 second. Repeat this until you get to the number 0. There is no need to use variables to simulate a timer.

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.

Designers can use their favorite design tools like Photoshop and Sketch to design the finest details of the user interface for their app. Single or multiple touch interactions can be applied on any UI element (layer) on each screen. Sophisticated animations can be created on-screen as well as screen transitions, using the powerful timeline animation features that Proto.io offers.

My own version of the Pandora Taylor Swift example provided by Proto.io's video tutorial.

A data visualization where a bar chart of faces flies out showing the details of individual faces.

An on-boarding carousel concept, created using Proto.io. It is implemented using state animations. Feel free to import into your Proto.io account.
