There are several sketching and whiteboard apps for the iPad, but Air Sketch offers a great feature that sets it apart: You can share your sketching and whiteboard sessions over a network. Anyone with a computer and a browser who’s on your network can follow along while you sketch, write, or go from slide to slide.
Air Sketch is technically recommended for sharing to just one computer, but I was able to share it successfully to two computers and an iPhone without any trouble.
You can use the app as a blank whiteboard, but you can also pull up images from your photo library. If you’ve preloaded your slides, for instance, you could use Air Sketch as a nifty presentation tool — and interact with those slides in real time.
Let’s take that handy feature one step further and use a computer that’s connected to a projector. Now you can use Air Sketch to deliver your presentation to a large room full of people without chaining yourself to a podium! Clever uses like this are how the iPad is going to change the way we do a lot of things.
There aren’t any text or shape tools in this app. Instead, you have five pen tools (pencil, pen, felt-tip, paint brush, and a highlighter). There are also eight color swatches, as you can see in the figure below, each of which can be customized with a double-tap.
There’s also an eraser, undo and redo, and the capability to save screen captures to your photo library with one tap. You can also e-mail one of your sketches as a PDF or as an image file.
You can pinch and zoom in on your sketches on your iPad, while the image stays full-screen for your viewers. This is handy for making smaller text or drawings.
