For those who want to take simple notes, draw sketches, or annotate photos.

This one burst onto the scene and immediately became the darling of artists and non-artists alike. It is just so easy to pick up and start using, with or without a stylus. Its free price tag makes it an absolute must-download, though of course, in-app purchases unlock even more features. It's simply beautiful on the iPad's retina display and a pleasure to use.

Why we love it

Paper is simple to use and comes packed with a ton of useful tools that make note-taking, photo annotation, and drawing easy.
