iGutenberg

iGutenberg is my self-contained Project Gutenberg ebook reader.
It has within it the text of about 28159 free books. After it is installed, iGutenberg neither requires nor uses Internet access. It's perfect for when you are in a rural setting or on a cruise ship, where the Internet may be unreachable.
iGutenberg lets you instantly search for books by title or author's name.
iGutenberg can read any book out loud to you using Siri's pleasant voice. If you're interrupted, it can pick up later where you left off. It thereby transforms 28157 books into audio books.
You can search for text within a book.
When you're reading a book and you like it, iGutenberg lets you email a copy to a friend.
This app lets you have multiple books open at once in separate tabs, and it remembers what is in each tab if you exit the app. It remembers where you were in each book.
iGutenberg is useful to people who live in countries where censorship and surveillance present a personal risk. iGutenberg does not transmit information about what you read or when.
iGutenberg is a large app, about 3½ GB, so make sure you download it via WiFi.
iGutenberg does not contain the entire English-language Project Gutenberg library; it excludes numerous books due to objectionable language and topic matter, and quality concerns.
