Ok, so I currently have iAnnotate and NoteTaker HD as my 2 main note/annotating apps. I am looking for an app that combines the good file organization and cloud storage sync options of iAnnotate with the better interface for making actual annotations on imported PDFs that NoteTaker HD has. Overall I really like NoteTakerHD, but the fact that you can't easily sync files with cloud storage directly from the app makes for a big hassle. I would ideally prefer an app that automatically syncs any changes on the iPad to the cloud rather than having to specifically export the files. Any recommendations would be much appreciated. Essentially I will be using this to annotate powerpoint lectures. I print the powerpoints to PDF and use my iPad to annotate the slides. Thanks in advance!
