Explore our library with more than 60000 curated ebooks from the public domain. The minimalist design makes it easy to browse by popular books, authors, or content tags from any selection. Offline reading means that once you open a book, it is downloaded to your library and available for reading at any time. The app home screen lists popular, classic works and is an excellent place to start browsing. Every book you open is stored in your library, and you can adjust the reading settings to change the font size of the books and switch between dark mode and classic white mode. The reader also allows you to choose ambient sounds and music to enjoy as your read. Choose from a selection that includes ocean sounds, rain, and morning birds to set the mood as you read. You can also use our ebook reader to upload books from your icloud/files or from a link.

I can’t do any kind of search for any kind of book unless it’s a book that the app is already picked. And I have to scroll through all of those I can’t just type in a name. This app is not worth anything. The only people who are telling you it’s good is those who have paid some thing for it. and I’ve read comments that the app creator wrote to other people and they are a bunch of lies.

Imagine a library with no written index and no tap on a title, or author or subject. Imagine having to look at the cover of every book instead of the title with author on a line. This was a good app until they recently 2025 ruined it. Plus they want fee for this irritation. Dont bother

It’s not better than native Books app for reading so what’s the point? Coming from an android user and Lithium app. This app is so basic. I’d like to see colored fonts and colored highlighting along with justified text so I can see more words on a page.
