📝 About this app
【Premier Reader】: This app costs $6, and our users are paying for it each and every day. Why? It is the best Gutenberg Reader: beautiful images, elegant formatting, and graceful page turning. Contents live from Project Gutenberg with last-minute update, more than 60,000 most important books ever published in history. Plus more than 7,000 human-read audio books.
【Audio books】: There are more than 7,000 human-read audio books, all for the price of a cup of coffee. Alternatively you could pay $3-5 for a single audiobook as some of the "Audio app" would ask you to pay.
【Book recommendation】: Every app gives you a list of book recommendation, but where did they find the list? dreamed up in 'lala' land? We base our recommendation solidly on big data, tens of millions of pages actually read by our users. Downloading or page flipping has no effect on the ranking of our recommendation list.
【Number of Books】: No other apps have more Gutenberg books, and many competitors are missing some classic Gutenberg books, and many competitors use outdated data from Gutenberg.
【Reading】: Texts and images are presented by a sophisticated book reader: beautiful presentation, graceful page turning, and the most intelligent Table of Contents (better than any other book reader for the same book).
【Read-along】: Audio and Text are synchronized when possible. You can read, listen, or read-Along, and switch between them at will.
【Export】: Export a book together with bookmarks and the notes you inserted into the book to anyone and any device, or save it i the cloud (google drive, one drive, or iCloud).
* The PAID version "Gutenberg Books" allows unlimited reading and listening.

🌍Geographic ReachNot ranked
This app is currently outside the top 100 grossing in all 9 countries we monitor (US, UK, DE, FR, JP, CA, AU, BR, IN). Niche or new apps often launch this way — popularity rankings appear once daily revenue clears the regional threshold.
Profile is built from iTunes Lookup + developer site scrape + ML revenue model. Empty fields show "Not found" — additional sources (Crunchbase, X, IndieHackers, Acquire.com) coming.
