Hello, I have a MBP, a Samsung Galaxy Note PRO 12.2 and an iPhone. Are there any good annotation software that has good cross platform support? I plan to annotate the same files sometimes from the Mac and sometimes from the Note PRO. I don't think I want to annotate using my small iPhone. It would be nice if the app could highlight/underline in different colors, add notes, etc. In the past, I used ezPDF Reader for Android.
