Diving into the DjVu format—pronounced "Déjà vu"—this compact and versatile document type is known for its efficiency, often achieving a file size ten times smaller than PDF while effectively storing scanned materials. There exist several online libraries housing a multitude of books available in DjVu format, with significant resources found at djvu.org.

A wealth of documents is accessible for free in DjVu format, including those at www.archive.org. Users can conveniently download materials via Safari and open them directly in DjVu Reader.

If an outline is present within a document, it is displayed and available for navigation to specific sections. The editable nature of the outline enhances ease of browsing.

The application features a slider for quick pagination through large documents, offering a seamless reading experience as DJvu documents are primarily image-based, representing pages through high-quality images that closely mimic the originals.

DjVu Reader provides comprehensive support for navigating various DjVu documents through simple gestures, including tapping on the left or right to turn pages and accessing full-screen viewing by tapping at the center.

Additionally, PDF support facilitates similar navigation features where outlines are available. Document positions are saved upon closing, allowing users to resume their reading seamlessly.

The developer actively invites suggestions for future enhancements to ensure continuous improvement of the app's versatility. The Help section contains extensive usage explanations and acknowledges potential future updates based on user feedback.

Future releases will expand support for additional file types as development continues.
