Very good but... – PDF Viewer - Annotation Expert Review

Love the app but don’t see a way to sync across my iPhone and iPad. Working with the app on Ipad is excellent but when I am away I want to open a document on iphone. I don’t see a way to do that (i.e., app doesn’t seem to have a way to sync across devices) Thanks for explaining how to sync using IDrive. Please add an FAQ to explain this. Works great. How about adding syncing capability using Dropbox?
