I love my iPad for a lot of reasons. One of them is sketching. Some of the draw programs are just stunning.
My favorite for just sketching is from Autodesk–Sketchbook Pro.
The “Insulin Kitchen” sketch is done in Sketchbook Pro.
There is another genre of sketch programs coming out that have a very different set of brushes and feel to everything. These apps are inspired by the Web Sketch app “Harmony” by Mr. Doob. My favorite of this batch is Touch Sketch published by Luksor. The reason Touch Sketch is my favorite of the Harmony inspired apps is because it supports the zoom-in/zoom-out (pinch) manipulation. This feature let’s me get in there and add detail that the others don’t.
The sketch “Lilac Kitchen” is an example of a sketch done in Touch Sketch.
