Good free reader app

So far, I’m okay with this app. Many setting, no problem with the books I read and it’s FREE. The only problem is when read epub, I can only set line spacing but not paragraph spacing. It’s hard to read. When my eyes leave the screen to look elsewhere, when return it’s hard to find where I read to. If it’s have distinguish between line spacing and paragraph spacing, at least I can see around second or third paragraph that I read previously. And it’s more pretty.

Hope you add paragraph spacing option in the near future.

Look forward to future development

There is a definite lack of cross-platform ebook clients (specifically, Windows-to-iOS) available now. In a perfect world, there would be an iOS version of Calibre, but it’s author has expressed no interest in this. FBReader has the potential to be this solution but it isn’t there yet. As of now, the functionality of this app is limited with, for example, no way to organize books into your own categories. It choked when I tried to open a PDF, citing a compatibility issue that doesn’t exist with the native Books app. Calibre integration is promised in a future update. I love the fact that the premium version isn’t rentalware and I would gladly pay twice the asking price once the operation and feature set is more fully developed.

Good but has bug with footnotes

Nice reader, but has bug with big footnotes. It shows pop up with just part of footnote. “More” button is shown sometimes, but mostly is missing for the book with lot of long footnotes I’m reading currently.

UPDATE: Fixed in 1.0.15, thanks a lot! Small issue with expanded footnote screen coloring is left. In the dark mode expanded footnote screen has white bottom section with “back” button. I think it should be dark as well.

Sorry for this. Fixed in 1.0.15 (already available for update)
