Postepic does also support social sharing to other platforms, as you’d expect. Though this doesn’t always work as you’d imagine. For example, testing sharing to WhatsApp the app merely created a generic text message with a link to view the quote in Postepic, rather than including the visual form of the quote in a WhatsApp message template (though this is likely a WhatsApp restriction on sharing from a third party app). A basic workaround is obviously to screengrab a quote and upload it manually where you like as a photo. Sharing to Twitter incorporated both the image and a text message with a link when I tested it. Konofalski says that with most “well known apps” it will automatically import/drop an image into the other app.
