You are looking for the app for your ipad, tablet, iphone, mobile device because you just can't live without your paper.li on the go!
There is no app! With the introduction of "responsive design" in October 2012, we discontinued our Apple app and no longer support it. You can still read your paper.li on your mobile device and/or tablet and access the settings via your browser. You can even use the bookmarklet.
Add the bookmarklet to an ipad (or tablet)
