I discovered an app for my iPhone that I've really come to enjoy. It's called Pocket Fiction and it lets you pull your favorites from FanFiction.com right to your device. The benefit is that it pulls the entire story and saves it for offline use on your device, so if you are going to be out of town and away from a connection, you can still read your Fanfiction.com stories.
Here's a link: https://itunes.apple.com/us/app/pocket-fiction/id453670574?mt=8
Hope others can find as much use for it as me!
