Forum users, I'm currently an Engineering student and I've been wanting a digital alternative to taking notes by hand. I'm a huge Apple supporter, so ideally, I'd like to do so with an Ipad. I have very specific needs, so I thought I'd ask some current Ipad users. I need a single app that can do the following: read .pdf/.doc/etc edit(both drawing and text) .pdf/.doc/etc (or add stickys with both text and drawing) create .pdf(or .doc) files with both text and drawing insert graphs/tables/etc audio recording maybe some sort of smoothening feature for the drawing aspects Also, how does the Ipad work with a stylus? Any help is greatly appreciated, Thank you.
