App and source notes
leaf is the best fit if your classics workflow mixes free public-domain discovery, imported book files, and focused reading on an iPhone. It can find books from Standard Ebooks and Project Gutenberg, import EPUB, PDF, and Markdown files, and keep reading journals, highlights, notes, and share cards alongside your books. It also includes reading themes and fonts, with custom fonts available through leaf Pro, plus optional Pro sync and iCloud Book Vault.
Standard Ebooks is best when you want a polished edition of a public-domain classic and are comfortable downloading or reading from the web. Project Gutenberg is best when breadth matters more than polish, especially for obscure works and older editions. Libby is best when a participating public library gives you access to classics, audiobooks, translations, and annotated editions without buying them.
Apple Books, Kindle, and Kobo Books are better fits when you want a commercial bookstore, modern editions, publisher annotations, or device ecosystems. Apple Books is strongest for Apple-native purchases, Kindle is strongest for Amazon libraries and Kindle devices, and Kobo is strongest for Kobo store users and Kobo e-reader owners.
