Bluefire Reader 4+

I love this app. For epubs and pdfs you cannot go wrong. The organization parts of this app are my favorite. I have hundreds of ebooks organized in here. The only issue I have had with it so far is when I have a page with highlights open and turn off the screen the highlights don’t show when turning the screen back on. They are still there and will appear again once closing the app and opening it again. Very minor bug.

I like that it’s more customizable than other readers, but there are a couple things that annoy me.
1) Every other reader I’ve used, when you leave the app and come back.. it brings you directly to the book you were reading. This app brings you to the library instead. I know I can just press ‘now reading’, but it’s an unnecessary step. Once you’re in the middle of a book, odds are high the you’re gonna continue reading that book!
2) the app hangs frequently! I can be reading and flipping thru the pages, when all the sudden it doesn’t respond. Swipe, swipe.. nothing. It’s not the iPad because I can switch apps and do whatever else I want while the app is hung. This happens on multiple newer devices. If you give it 10 seconds or so it seems to come back, but it’s pretty ridiculous. The app has one purpose and that’s to display text. It has all kinds of time to have the next page ready while I’m reading the current page ** added note here, when it hangs it always seems to be at the end of a chapter
3) this is minor, but with all the freedom you have to pick your background and text color.. you don’t have the freedom to pick a highlight color. I had found an interesting color combo, went to highlight something and it didn’t highlight because of my color scheme
4) also minor, when dealing with RGB color selection, I’m used to seeing 0-255.. but for some reason this app uses 0-100.

This is probably the best flow and rendering of ePub documents I’ve seen. It displays clear, high quality text that is a pleasure to read. It’s library capabilities and replication via third party file engines, cloud or private is up dependable and convoluted.
I use OneDrive and File Manager, and one would think that adding documents or folders should be easy. But it isn’t, adding items is an onerous task and does not add them to the library. The collections in the library cannot be organized by the document folder structure, but all appear to be dumped in one huge pot. Each individual document then must be manually moved to a collection manually. Collections are at one level only, so there is no hierarchy for Collection organization.
I can also not see if a document in the library is copied in the apps’ storage or if it is simply a link to the original location. Obviously no internal document / file management exists.
Perhaps I’m incorrect, in which case I would love to correct my initial impressions. Certainly for a product associated with Adobe, it is a huge disappointment.
