National App Day is observed annually on December 11.  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 as our mobile cellular phones incorporated smart technologies including processing chips, internet connectivity and touchscreens.

Since that time apps have changed how we work, live and play.  They have created thousands of new companies, millions of new jobs and billions of dollars in revenue.

National App Day was submitted to and accepted by the Registrar at National Day Calendar in December 2017 by CJ Thompson, founder of Platinum Edge Media.

The purpose of National App Day is to celebrate the importance of apps as they change our collective culture by organically promoting creativity and innovation.

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.  Today there are over 2 million apps on both the Apple and Android platforms and thousands more introduced daily.
