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.

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. If you would like to see how I created this prototype, please watch this video tutorial here: http://docs.proto.io/videos/pandora-tutorial-part-1/
