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 NekomimiViewer is completely free with no ads. See the bundled license notices and the published privacy policy for details.
