Apple quietly announced that as of yesterday, its Cards service for iOS is no longer available, putting an end to an unusual standalone app that debuted in October 2011.
A support page notes that “Cards ordered before 1 PM Pacific time on September 10, 2013, will be delivered, and push notifications will continue to work.” Previous purchases can still be viewed in the app’s Saved Cards feature.
On the same support page, Apple recommends using iPhoto on the Mac for ordering letterpress cards with customized photos and text.
