Scribble is a handwriting canvas for school kids: take notes, do your homework, or work through exercises with a pen, stylus, or your finger.
Write and draw freehand on pages with ruled, squared, music, and other school-paper backgrounds, or import a worksheet as a PDF and write right on it. Hold the pen still after drawing a shape, arrow, or diagram and it turns into a clean version that can be reshaped afterwards, and scribbling over a drawing deletes it.
Works with a graphics tablet pen, a touchscreen, a touchpad, or just the mouse. A built-in Help explains the gestures.
A release for selecting with the pen and for touch that gets stuck.
