Ratings & Reviews
- This app has not received enough ratings or reviews to display an overview.
This update brings a table of contents and bookmarks to PDFs, makes EPUB reading progress more accurate, and lets the free version try AI and highlights before you decide to upgrade.
PDF CONTENTS & BOOKMARKS (free)
• Reads the table of contents built into your PDF, keeps its chapter levels, and jumps to any entry with a tap
• Bookmark any page while reading a PDF; each bookmark is labeled with its chapter and page number
• Bookmarks are listed in page order — tap one to jump right back
MORE ACCURATE EPUB PROGRESS
• The overall percentage now reflects each chapter's real length, so covers and copyright pages no longer eat up a big chunk
• The bottom bar now reads "Ch. 2/3 · 45%", making it clear these are chapters, not pages
• Page mode also shows your page within the chapter, e.g. "Ch. page 5/12"
• With many chapters or larger text, the label shrinks to fit instead of being cut off
TRY AI FREE, 3 TIMES
• The free version can now try on-device AI — summaries, Q&A and vocabulary — 3 times in total
• Each generated result counts as one; Q&A and vocabulary only count once you send your question
• The AI panel always shows how many tries are left; after that, unlock unlimited use with a one-time Omnia Pro purchase
• More reliable summaries and Q&A for long Chinese text, with fewer "too long" errors
• Requires a device that supports Apple Intelligence
TRY HIGHLIGHTS FREE
• The free version can create 3 highlights in every book
• Changing colors and deleting highlights never count and are never limited
• The highlights list and Markdown export are always free
As always: fully offline, no tracking, no ads. Your books stay on your device.
