AppAdvice has teamed up with Alberto García Hierro in order to offer you a chance to win one of one hundred and thirty-eight (138) promo codes for Printful for iPad, iPhone, and iPod touch ($2.99).

Sure, there are plenty of news readers and browsers that natively support RSS feeds, but what about a client that’s simple, elegant, and can move with you on the go? Not only does Printful streamline articles for you, making it easier to read, but you can start an article on your desktop computer and move to your iPhone or iPad if it becomes time to head out for the day.

Adding a news outlet, blog, or other site source is just a keyword or URL away. Tap the Add (“+”) button in the top-left of the Sources pane. For iPad users, this is revealed by tapping on the RSS icon in the top-left. For example, searching for “AppAdvice” will have the result of http://appadvice.com. Searching directly with the AppAdvice URL or tapping on the URL search result will provide you with the URL of our RSS feed. Tap on it, tap Search, then tap Close. If you would like to change the order of the list, use the Edit button in the top-right of the Sources pane.

The iPhone and iPod touch side offers two articles per page in either landscape or portrait viewing, while the iPad can list a handful or more. Navigate the pages with a simple left or right swipe. As you should have guessed, tapping anywhere on an article preview will make it available for full viewing.

Within an article, you can close it, mark it for reading later, star it as a favorite, adjust font attributes and theme, and take further actions. There are options included to increase or decrease font size, choose one of five themes, and choose one of six fonts. The actions button allows for sharing via Twitter, Facebook, or email, plus opening the page in Safari or sending it to the archive.

Having a free Printful account permits synchronization amongst devices and gives the ability to streamline articles in nearly any web browser. The Bookmarklets are what allow you to send articles to your Read Later list, which can then be viewed within the app after a quick sync, or view them in a streamlined format using the Printful website.

As a special bonus, we will be giving out the first 38 promo codes to the first 38 readers who leave a valid comment below. The remainder will be distributed in the standard random fashion.
