iPad: Paper, the simple but powerful drawing app for the iPad, has been updated with a slew of improvements. This includes a new zoom function, better ink tools and a new iOS 7 design.
The iOS 7 functionality makes Paper faster and more readable. Likewise, the way zoom works now is easier to use. When you zoom in, your drawing tools adjust their size as you zoom so you have finer control. Inking also gets a bump with a new dotting feature where dot size is no linked to how long you press. Tap quickly to make small dots, hold down for bigger ones. It's pretty simple, but it really makes drawing a lot easier.
