Would you like to jot down notes on your iPhone’s gorgeous touch screen? Are you missing a way to sketch a simple diagram as a quick reminder? Will your children like to draw on your iPhone, maybe on top of a picture you shoot with the camera? Sketches is a native iPhone application that will allow you to do all that. Scribble your thoughts quickly, select a picture from your photo album to draw notes on top, or shoot a photo of your friend just for the sake of putting a moustache on her face 🙂 You can even erase your drawing by shaking your iPhone, as if it were an etch-a-sketch!
