National App Day on December 11th encourages us to explore all the possibilities apps afford us.


The word “App” was listed as the word of the year in 2010 by the American Dialect Society.   

Short for Software Application, apps quickly appeared when our mobile devices incorporated smart technologies. As the power of our phones increased with processing chips, internet connectivity, and touchscreens, so did the apps that became available.

Since that time, apps continue changing how we work, live, and play. They offer opportunities, too, by creating thousands of new companies, millions of new jobs, and billions of dollars in revenue.

Apps accelerated in growth with the advent of Apple’s iPhone in 2007. In 2008, Apple introduced OS 2.0, which included approximately 500 apps and allowed third-party app generation. Over 3 million apps on both the Apple and Android platforms offer a plethora of options for business, productivity, entertainment, organization, security, news, and so much more. And every, programmers introduce thousands more.

Not only do apps keep us connected and organized, but through customization, apps fit our busy and changing lifestyles.

Beyond games, what tools do you use to save money and time?  While you expound on your favorites, explore new apps, too. What kinds of apps do you predict for the future?
