Import your books

Tap the plus button at the upper right of the library and choose an EPUB, PDF, TXT, MOBI, AZW3, DRM-free AZW or FB2 file in the system Files picker. The file is copied into the local library. Importing the same file again finds the existing book.

Annotate a page

Use Apple Pencil while reading, or tap the top pen button, 画图工具, to show the drawing tools. Tapping that button with a finger enables touch drawing while the tools are open. Long-press selectable ebook text to add a highlight or handwritten margin note. The PDF more menu includes 导出带批注的 PDF for annotated PDF export.

File compatibility

The current version supports DRM-free files up to 256 MB and does not open encrypted PDFs. Complex EPUB layouts may differ from the original. Use PDF for fixed page layouts. Scanned PDFs support handwriting, while OCR text selection is not available.

Reading data and backup

Books, reading progress and annotations are stored on the current device. Export any annotated PDFs you want to keep before removing books or the app. System backups depend on device settings. The developer cannot restore content deleted from your device.

Annotation Lifetime and Restore Purchases

Starting with version 1.0.1, importing, reading and page curl are free. A one-time non-consumable purchase unlocks handwriting, drawing, highlights and margin notes. No subscription or automatic renewal. Prices are localized by the App Store. Existing annotations remain viewable and exportable. Open library settings and choose Annotation Lifetime, then Restore Purchases using the original Apple Account.
