Display your library in a list or grid layout and sort you books applying filters by path, name, size, date, etc.; and there is even a filter to help locate specific documents or document groups (e.g., Recent)
All documents are easily identified by thumbnail covers and detailed descriptions.

Documents that you read can be locked into a vertical-only scrolling mode and set to be flipped page- or screen-wise.
Librera Reader supports text reflow and annotations in PDF documents.
Configurable functionality of the volume keys, customizable fore- and background (textured or solid-color).

The list of features goes on and on and on!

This means that the only way to truly appreciate Librera Reader is to try it out.

Note: fixed!!!!! My joy is back!!!! 😄 It used to give me a notification like option that let me move forward a page when listening to things being read, but it is no longer popping up. Overall, it would be nice to have the option to skip half a page instead of having to make the words large to do so. It occasionally will not move forward a page when it is reading out documents or epubs and the "replacements" in the read aloud will act up. In the end, this is my absolute favorite app either way!

I used the free version (tts reader) for six months, then purchased the pro version. The only difference is that the pro version doesn't have ads. But the ads in the free version were inobtrusive. I use the app for proofreading, and I run it for long sessions. The program will go completely dark, and there doesn't seem to be any logical fix. I just try various things, and it does come back, but it's annoying.

this app is peak, I have found nothing else that works this well for reading ebooks out loud to me. Best money I ever spent some things I'd love to see implemented are - better search functionality for browsing my files--it's not very reliable right now - ability to set pronunciation for certain words in a personal dictionary (for things like character names that consistently get mispronounced) - ability to automatically organize different versions of the same file (if they have the same name)

This app is awesome. It reads all of the most used ebook formats and more. The only real criticisms I have are the inability to add one of my folders to my library despite reading and adding other folders just fine. It reads the books in the folder, but it just doesn't add them to the library. It also doesn't seem to have a way to fit to width. But I love the way it allows scrolling or traditional book reading.

I've shuffled through what I believe are the Big Three with Reader apps (Moonreader, Readera, and this one Librera). I've bought the pro version of all three as well. I think I might like this one best and more so than Moonreader. I'd have given it 5 stars if it had the page turn sounds like Moonreader does. It's not a big thing, but the sound is still a nice treat when turning those digital pages.

This is a great, very versatile reading program with many features and supports many file formats. It has been especially helpful to me with my dyslexia and low vision. Its more than worth a try. You will love it. Preserves sketches, diagrams, and photos. Great for reading PDFs, ebooks, even comic books. Many text formatting options for ebooks. Cant say enough good about it.
