I love this app! It enables the user to read books and papers in any format.. PDF, epub, MOBI, txt, etc and is more customizable than most. The app allows one to change a wide variety of settings, including the font, color, format and style of the file, according to personal needs and preferences. An all in one reader that replaces the need to have separate apps for each type of file.. convenient and highly useful. 😻

I've been using this app for a couple years now. Because I have such limited time and/or brain bandwidth to read, I use the TTS feature almost daily. That being said, this most recent update did some damage to my TTS accessibility. Much of what I listen to has foreign names, words, pronunciations, etcetera in them. The update wiped out every single exception I had and all of my settings. It installed on its own today and wiped out EVERYTHING besides one bookmark and one favorite. Ouch. :(

One of the best Reader Apps I've found that is versatile and can do more than I need. At times it can be a bit to technical with options I don't understand so I just try and keep it simple. Once I found a complimentary TTS Voice App that wasn't completely digital sounding I was good to go. Now I use it to read PDF copies of books from time to time or downloaded ebooks from a subscription service. Only reason 4 stars is because it can often be confusing and not so user friendly for simple stuff.

App is slow to start and loading book pages sometimes lag. There is no manual or instructions on using this app anywhere and with so many settings it is hard to know what is what. The app does not open to the book you are reading or the page and the page you left off on as other ebook apps do. The app seems to also be using a lot of data - and my ebooks are all in my phone's memory so there is no need for the app to be using my data. There also seems no way to shut that off.

It's just OK. No way to edit document or file info such as title or author like other readers allow. Reading view is good and easy to work around, but I'd describe the main library interface as "nerdy", showing a lot of options and controls without a lot of effort to clean or streamline the UI. It works, it does most of what I like, and the problems aren't deal-breakers.

The reading settings do not work. It will only display justified text. I prefer left justify which doesn't work so I tried all others including center and none of them work. If I change from portrait to landscape it changes your place in the book, and when you go back to portrait it doesn't even put you back to where you were. Completely unusable.
