Instapaper Pro essentially turns your iPhone into a streamlined e-reader, saving your favorite articles as you zip through the Web.
Bookmark an article in your Web browser and the text is saved to Instapaper to read later, even if you're offline. You can also set a folder to feed content in real time from your favorite sites as they post updates.
Once you're reading articles, you can change the font size and style, email the text to a friend or add a star to your favorites (friends can subscribe to your starred list). For one-handed viewing, tip the iPhone forward and back to scroll through the text. And if you don't want to shell out any cash, a free ad-supported version of Instapaper is available without some of the Pro's features.
