We are seeing “card views” in sites like Medium and Cowbird, where engagement is the focus of the screen. I think the way this writer conceptualizes cards across screens, and shows how they will work on wearables and mobiles, makes it clear that APPS are a passing phase.
“In a world where notifications are full experiences in and of themselves, the screen of app icons makes less and less sense. Apps as destinations makes less and less sense. Why open the Facebook app when you can get the content as a notification and take action — like something, comment on something — right there at the notification or OS level. I really believe screens of apps won’t exist in a few years, other than buried deep in the device UI as a secondary navigation.” (via The End Of Apps As We Know Them – Inside Intercom)
