I would rather stick to the default Notes app or something. In this app you can draw things, but it's really difficult. First off, these ads keep popping up every 5 seconds. Then, if you mess up, there's no eraser and you have to start all over. You can change the backgrounds too, but they all have a really bad resolution. The graph paper looks fake and pixelated. Also, I can't really imagine anyone needing this, but I suppose you can. Still, when you use your finger to draw, the lines are very off.
