Calibre is great for managing an ebook library, and okay for reading ebooks but the reader is clearly not its primary focus, so I’m wondering what readers folks here use across platforms.
I know of a few, but I’m always on the lookout for different options that may have features I didn’t realize I’d love to use.
Depends on device for me. For android I use Librera for books, Tachiyomi/Kotatsu for manga/comics, on the old Kindle I was gifted (Kindle Touch 2) I use KOReader so I can read epubs. For desktop I do use Calibre for reading, though I’m not a big fan of their reader. I mainly read textbooks on desktop and find the search features useful, which is the main reason for using it, it all works well enough. I had issues getting Okular to work well on my computer, but I’ve heard it’s good? Here’s hoping I can unify things a bit in the future.
Eta: I forgot I actually started using Seeneva for comics, since I like the speech-bubble zoom feature
Which OS were you trying it with? I was pleasantly surprised when I found it was available on Windows, and a simple install had it working for me. Another option to consider if it still gives issues (and you’re on Windows) may be SumatraPDF, which despite the name supports a wide range of formats.
