We've come a long way since 2010, when the American Dialect Society named "app" the word of the year. Even today, mobile devices and their ecosystems show no signs of slowing down. Quite the contrary, in fact: in 2020, the App Store ecosystem alone facilitated $643 billion in billings and sales, up 24 percent from 2019. Impressive, right? And while we have reached a massive scale of adoption and an interesting level of polish, it seems that a wave of creativity has yet to sweep our mobile devices into a new era.
