Hi - so I am new to iPad world. I am a researcher.
I am looking for an app that allows me to annotate PDFs, write on it and keeps in sync in-place the original location in Dropbox.
I don't want it to make a local copy or create a separate folder.
I have read some articles abouth this, but still haven't found the ideal app.
Which one would you recommend for me and why?
Thanks in advance.
