The only options you have are changing the size of your pencil/eraser/text to “Small”, “Normal” or “Big” and to use one of the 5 pre-defined colors.
There’s no undo command. You’ve either got to manually edit out the things you’ve drawn using the eraser tool or start over from scratch. And if you navigate away from the web page while you’re drawing, you’ll lose all your work.
You do get a saving feature that allows you to save what you’ve sketched as an image.
This online drawing tool is great for people looking to find a similar experience as using real paper and pencil; just hook up your graphics tablet to your computer or get yourself a stylus pen for your tablet and you’re good to go.
With a pencil and paper, you don’t have an undo command that you can use as a crutch that rapidly rescues you from any drawing mistakes. You also don’t have access to built-in vector shapes or fancy brushes.
But perhaps the simplicity of PencilApp and its unforgiving nature when it comes to slip-ups is just the ticket for unleashing your rawest creative ideas.
PencilApp was built by Clinton Skakun, founder of online digital agency Skakunmedia. He built the online drawing tool’s layout from scratch using HTML5 and CSS3 (i.e. no front-end framework). For the drawing functionality, Clinton used a jQuery plugin called jqScribble by Jim Saunders.
PencilApp just launched November 22, 2013.
