NekomimiViewer is a media viewer built for browsing deep image, video, and PDF libraries exactly as they are organized on disk. Point it at a local folder or a NAS (SMB share) you choose, and it becomes your media library—no import, no upload.

■ Highlights

• Fast browsing of deeply nested libraries Even huge folder trees scroll smoothly in grid view. Deep chains of sparse folders are automatically flattened into a single readable view.

• Direct NAS (SMB) connection Add your NAS and stream videos and PDFs straight from it—no need to download entire files to your device first.

• Images, video, PDF, and audio in one app The built-in viewer handles a wide range of video formats including MKV and AVI (FFmpeg bundled), two-page spread PDF reading, and thumbnail grids for images.

• Mini player for watching while you browse Keep a video or track playing in a small window while you explore the library. Playback continues in the background, with repeat, shuffle, and lock screen controls.

• Works as a music library Audio tags (title, artist, album art) are read automatically. Switch to the music list view to sort by track number or tag.

• Downloads for offline viewing Save files from your NAS to the device and view them offline. Interrupted transfers resume where they left off.

• Automatic thumbnails Generated and cached entirely on your device—first frame for video, first page for PDF.

• Full-text search (file name and path) Fast search across the whole library. Folder paths can optionally be included in the search.

• Favorites, star ratings, and history Mark the files you open often and jump straight back to them from your history.

• Tuned per folder Grid, list, and music list view modes are remembered per folder. Rename roots for display, and act on items from the long-press menu.

■ Privacy

• No personal information or usage data is collected—ever
• No tracking, no analytics, no ads, no account required
• All files, thumbnails, and favorites are processed and stored on your device only
• The only network traffic is reading media from the NAS (SMB share) you registered

■ Who it's for

• Anyone who wants to browse a photo or video collection stored on a NAS from an iPhone or iPad
• Anyone who wants to stream a music library kept on a NAS
• Anyone who reads local PDF libraries in two-page spreads
• Anyone who values privacy and would rather not hand their data to an external server
