I’ve long been a fan of Paper by FiftyThree, grabbing the app when it was first released. Then I also bought their stylus, Pencil. Combine the app and the hardware, and you’ve got a really natural drawing interface on your iPad.
Now, FiftyThree has updated Paper with a new set of tools: Think. Given my inclination for precision, these are my favorite kind of drawing tools. Via its “intention engine”, the Think toolset lets you quickly draw all manner of shapes, fill them with color, and cut, copy, and move them around. That means I can create diagrams, charts, and mockups with just the right combination of polish and “hard-drawn” feel.
Think Kit’s Diagram, Fill, and Cut tools make it fast and easy to draw charts, diagrams, graphs, flows, wireframes, and models. Use them to sketch perfect shapes and connectors, and create presentation-ready visual model. Anything you create can then be exported directly to PowerPoint, Keynote, or your favorite iPad apps, and shared with colleagues everywhere.
