I was looking for an Android app for a complete management of PDF files (reading, searching, editing and so on) that was as feature rich as possible and FREE.
As first to notice, I came across several free PDF reader/viewer which seems to be like clones the one of the other and that I consider rubbish: who can go with apps that sacrifice reading space for ads?
Of course I tried the Google "default" PDF reader but it only provides basic reading functions.
The Adobe Acrobat app (I had to try that too, obviously) could be ok but it offers very little in editing features for free (things like page-reordering, document creation/modify, etc. all requires paid subscription).
For the same reason I could mention Moon+ Reader or Universal Book Reader which I look at quickly and looks nice (Moon+ Reader in particular) but I have to keep them aside because they're more intended as readers than editors and come with very limited editing features while I am looking for a unique app to install and do everything with. At the same time, I don't want to install some "dispersive" office bundle application with PDF features/add-ons but something that is mainly focused on PDF documents.
So... What else can I use for my needs?
EDIT: following @NicolasRaoul comment I list minimum edit features requested that the app must provide:
- rich annotation capabilities = at least highlights, underlines, free text, shapes (at least arrows and rectangles), notes/comments;
- form filling with signatures.
The features to add new pages, rotate/rearrange pages and create new PDF documents from scratch would be a plus.
If ads are present, they must not be intrusive ones and they must in no way be shown while reading (distracting and stealing space).
Finally, the app must be able to open multiple documents and provide a comfortable way to easily switch between them.
