Popular sketch app Paper, by FiftyThree, received an enormous update today, bringing the software to version 3.0. As expected, the new release brings about iPhone support, as well as several other new features like swipe-to-style notes and annotation tools.
Once seen as a casual sketch app, Paper now seems more like a catch-all brainstorming and note-taking app in version 3. It allows you to capture images, draw on them using the built-in tools, add custom text, and then share your creation in a variety of ways.
