can you please tell me what other apps you use?
I only used iAnnotate for simple annotation, insertion of text and doing millions of searches. So take this comparison with a grain of salt.
I think iAnnotate is more like a scalpel and PDF expert is a knife. For example iAnnotate got over 200 different stamps while PDF expert has only 20 or so. For most people PDF expert will suffice but selected few might find iAnnotate more useful. PDF expert however has much better UI and offers other nice features besides annotation such as adding or deleting pages, adding full size images into a PDF (iAnnotate let's you create a stamp out of image but it won't let you insert full size). iAnnotate however got a better search UI since it slides in from the side and doesn't cover the PDF while PDF expert got a pop out search box. There are UI issues that I have with both. The biggest problem I have with PDF expert is that it doesn't allow smooth scrolling between pages. I have emailed the developers about it and hopefully it will get fixed. So to sum it up, I think iAnnotate will benefit people who have specialized needs in annotation and only annotation while PDF expert is more like a PDF editor.
Thanks so much for that, that's very useful. Yes, the main reason why I now predominantly use PDF Expert are intuitive and easy to use interface, and that it seems to sync much faster/ easier with DropBox.
At the moment, my main usage looks like this:
PDF Expert is my main tool for annotating pdfs, although I still use iAnnotate from time to time because I want to keep exploring it until I understand its full potential.
I use 7notesHD and Notability as my main note taking apps (and often export from there to Evernote), especially when I do handwritten notes or draw little models or diagrams. There are also some notes that I put directly into Evernote. It's a bit random what goes where, as I'm kind of in the process of testing out different apps with a view to establishing a more fixed system.
For audio notes, I presently use Evernote for smaller, note-to-self kind of messages, and Voice Memos if I want to record a lecture or a meeting/ longer conversation. I recently downloaded PaperPortNotes and will try to use this next time I audio record and take notes at the same time. This app has a function where a new audiofiles inserts itself on each page, so that you don't have to scroll through pages/ audio to sync - the text and the audio come together on each page.
I use iThoughtsHD for creating mind maps, and at current I've got that connected up to Xmind which works on pc and mac, and you can also access the maps on the web.
I've recently downloaded Papers but haven't had time to explore it, which I will do over Christmas. I haven't figured out yet how that usage would complement my other apps, but it seems to 'talk to' various scholarly search engines. I've also downloaded the Taylor and Francis Online app.
Otherwise I use Pages, Numbers and Keynotes when dealing with docs I've produced on my work pc.
Finally, I've downloaded an app called pdf-notes. I don't think it does anything that PDF Expert doesn't do for me, but I just got curious and decided to look at their free version.
I'm not quite sure how to work with references on my iPad, but I'm hoping Pages will take care of that. I've downloaded a couple of free reference apps (BibReader and Mendeley), but at work EndNote is the officially supported program that comes with IT support, so I'm reluctant to use something that can't 'talk' to EndNote because I'd like to avoid too many parallel systems.
