Flagged Pros + Cons
Con Free version contains ads
The Pro version has no problem. Alternatively, the fdroid version works as well, though it might be annoying to those who want cloud integration because the fdroid version doesn't have cloud integration.
Pro Ad-free open source version available
"For better security, the F-Droid version, is based on the latest MuPDF and does not require access to the Internet.
For the above reason, some Internet-related features of Librera Reader are missing in its F-Droid version:
1) Access to OPDS (Calibre) Catalogs
2) Google Drive Syncing
3) Access to Clouds (Dropbox, Google Drive, OneDrive)
4) Saving (sharing) pages from web browsers
5) Rendering MathML formulas in EPUB3 books
6) Access to the What's New page."
