Need Preview app on iOs

Thanks for the reply. When I work on my MacBook I save dozens of .pdfs every day in to my Dropbox folders. I can easily navigate to that folder on my computer, open the .pdf and work with it. In Preview, I can drag and drop whole .pdfs or just pages from other .pdfs to easily amalgamate these files. I can rename them directly in Preview and can re-order pages from the thumbnail view. I can then duplicate and delete or add pages as needed. Following that, using the MarkUp tool, I can highlight, then add typed text, and insert my saved signature. All of this is what I do all day essentially for my business. I’d love to have a pencil and be able to take the clients these .pdfs to sign directly on the tablet but not if I can’t work with them easily, or store and retrieve from Dropbox without issue.

Thanks for those. I have tried some of them, incl ones I paid for but was generally frustrated that none of them did all of the things Preview does (plus a built in app is key too I think), and it was really clunky opening multiple apps with the same .pdf(s) to edit them. Appreciate the suggestions though.
