PencilApp is a bare-bones online drawing tool designed for your tablet and your computer's Web browser.
Unlike other similar online drawing tools — such as draw.io, QueekyPaint or Sketchpad, for example — PencilApp just has a pencil, an eraser and a text-typing tool.
They say don't expect a massive array of features, which actually sound kind of nice. We don't traditionally have an Sketchpad. This app has a handful of option instead of the dozens. This is similiar to the pen and paper sketches, so give it a try.
