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.
I had a similar experience. Back before epub took off, I started reading Gutenberg books on my wince phone. I think I was using an app called jbookshelf. Even then I loved the convenience of it.
Once android happened, I switched to epubs and it was so much better.
Now I’m mostly using koreader, along with kindle and Google play books. I prefer reading anything in a foreign language on Kindle, because it’s so easy to look up words.
