These little gestures shortcuts are much faster than navigating menus, allowing you to focus more on painting. Holding a finger down on the screen for two seconds will activate the eyedropper tool. Swiping three fingers right or left will undo or redo the last action. A three-finger tap anywhere on the screen displays or hides the toolbar and other icons. Dragging up or down will adjust the opacity of the brush. By tapping the middle of this circle and dragging your finger left or right you can quickly adjust brush size. A little circle at the bottom of the screen brings up a large circle in the screen’s center. Sketchbook Pro’s interface has a slight learning curve to it, but before too long, you’ll find it to be well thought out and quick to navigate.

An eyedropper tool lets you pick colors off the screen. Underneath the color wheel, you’ll find sliders for hue, saturation, and the amount of black you want in your color. I also appreciated the app’s color selector, which has several color swatches and a Painter-style color wheel with a saturation diamond in the middle for choosing virtually any color imaginable. Of course, there’s an eraser brush and a paint bucket tool for filling the entire canvas in one tap. There’s even a smudge brush that will smear previous strokes-a nice tool for blending your paintings.

You can also set the minimum/maximum radius and opacity so the brush stroke will taper or fade out at the end of a stroke. Each brush can be customized by adjusting its radius, opacity, feathering, and spacing. Sketchbook Pro probably has the most powerful brush engine in the App Store, with 60 different brushes ranging from pencil, soft round, and stippling to square, airbrush, and splatter you can even opt for several symbols like tree leaves or flowers.
