My drawing abilities stopped evolving some time around the third grade, so I tend to avoid situations where I need to sketch something out for other people, especially if it has to happen as part of a live conversation. My debilitating lack of artistic skill is the reason I was intrigued by Think Kit, a new set of tools for the Paper app from FiftyThree. It uses the company's patented Intuition Engine to translate my wobbly circles and miserable sense of scale into a sharp-looking flow chart or Venn diagram.

Paper is one of our favorite drawing apps, perhaps not the best for professionals, but certainly for the casual user. For a while it was one of the top grossing apps on iPad, and critically acclaimed by creative types. But the company has been shifting to target the enterprise and education markets, which means figuring out ways to help people be capital P "Productive." It's also changing up its business model, making all its software free and hoping to earn its money by selling its Pencil stylus.
