When designing your app, you often want to provide logic for when X happens do Y. Apps provides the ability for these dynamic actions:

• X is called an Event.
• Y is called a Rule.

• When the "Submit deposit" button is clicked, run an automation.
• When the value of the "Cash In" textbox changes, change the label color to red if the value is < 0.
• When the help icon is clicked, open the browser to show a documentation page.
• When a tab button is clicked, change the page container to show a different page.

By specifying what rules to execute when an event occurs, your app transforms from being a simple display of information to an interactive console.
