iPhone: Unroll.me has long been one of our favourite ways to destroy spam in your inbox, and today that experience extends to the iPhone.
The Unroll.me app isn't all that different from the desktop versions, but instead of just clicking on boring newsletters you don't want, you'll do a Tinder-esque swipe action to unsubscribe from them. The daily digest of newsletters you actually want is still included here as well, so you can view it in the app instead of clogging up your regular email client. If for whatever reason you haven't been able to use the web app, the iOS app will certainly help you clear out your inbox.
