Is it okay to (mis)use Referer header for "share with app" functionality?

Consider a website where some links are intentionally designed to share 
the page with another website/app. Instead of using proprietary APIs 
between the apps, is it okay to just use a referer?

Of course, the target app would also need to support using a referer for 
it. So maybe it would be better to just use something else entirely. And 
maybe links in a page shouldn't be able to do it - what if it required, 
say, user-defined bookmarks instead?

Just some thoughts. Feedback welcome.
