EPUB structure, paragraphs and available cover artwork are preserved whenever possible.

FIND YOUR PLACE AGAIN Kindphone saves your exact reading position, recent books, bookmarks and reading preferences locally. Switch between scrolling and page-turning modes while keeping your place. NAVIGATION TOOLS Search within a book, use bookmarks, browse detected contents and follow transcription progress for scanned documents. YOUR DOCUMENTS STAY YOURS Document extraction and OCR happen on the Device. Kindphone does not require an account to read.
