Pearltrees has launched a new iPhone app that allows users to create a virtual library of all the things that they like. The mobile app takes all of the features from the web interface and optimizes them for a portable experience. The Pearl view lets users see an overview of any topic, while the reader lets contributors browse from page to page with just a swipe of the finger. Other features include the ability to add text-based notes, organize photos, and browse through all of the sites content.
