How to Create an App

In a world where everyone is glued to a smartphone, the market for Applications, usually shortened to Apps, has exploded virtually overnight. Apps allow users to do… well… pretty much anything. “There’s an app for that,” after all. Apps have been created to serve what seems like every form and function: mobile gaming, mobile banking, and mobile learning have all become phrases commonly used in our vocabulary today. It seems like things we once had to go out and do in the “real world” can just as easily be done from a phone’s touch screen, and you can bet that people are making a profit from it. But what exactly is an app? And how does it work?

As explained in the article, How to Create an App, Apps can divided into two categories: Native and Web apps. As you might be able to guess, Native apps take advantage of built-in hardware and software on the device to perform whatever functions they were designed for, and Web apps use the internet to do the same thing– that is, they actually function in the web browser, but “look and feel like a Native app”. Many apps are a combination of the two, having features that can be accessed with just the phone’s hardware, and additional features that are only available with an internet connection.

Apps are written in programming language, just as all computer programs are written in programming languages. For the Apple iOS, Objective-C is the primary Native app language. Android apps use Java, and Windows apps use C#. Web apps across platforms use HTML5, CSS, and JavaScript.

Once past learning and writing the basic code for the app, app builders can use storyboarding design tools to format the layout and look of the app. Next, they program the logic and data storage of the app, which ensures that the app functions as you would expect it to. For example, you press a button and the button responds by leading you to a new page, where you then enter information, press another button, and have your information stored in the app for future reference. Once this is complete, the app can be tested, and then published for public consumption.

The article goes more in-depth about the programs available for app creation and development, and concludes by stressing the importance of continued development of mobile apps as people continue to demand these applications on their mobile devices.
