2019 was a confusing year for apps. The Universal Windows Platform (UWP) was declared dead. Progressive Web Apps (PWAs) didn’t take off in any meaningful way, again. Mac Catalyst landed with a thud. And Linux apps, inexplicably, were everywhere.
Only people like you and me worry about this stuff, of course. To most users, apps are apps are apps, and how an app is made---or how an app is not made---doesn’t matter in the slightest. What does matter is that the apps users want are available on the platforms they use.
