Drowsebook is a local-first reader for personal DRM-free ebooks. It imports EPUB, PDF, TXT, MOBI, and AZW3 files, keeps the bookshelf and reading position on the iPhone, and reads text aloud with Apple's system voices. Narration can continue in the background with Lock Screen controls and quick skip buttons. PDF cleanup rules can hide page numbers, footnotes, short headers, captions, or custom patterns, while per-book dictionaries help with files that need manual cleanup. The free version lets a reader keep two of their own books; the App Store lists a one-time Drowsebook Buy Once purchase for $19.99 and a $39.99 Supporter option that the developer says provides the same access. There is no subscription or account system. The developer says book files stay on the device; optional reading-position sync is off by default and sends only a cursor and optional bookmarks to the user's private iCloud database. Encrypted books and some newer Kindle variants are not supported. Drowsebook requires iOS 17.0 or later.
