Rukomi is a comic reader and local library manager built for comic collectors. Import and organize comics on your iPhone or iPad, or access remote libraries through SMB, WebDAV, or OPDS. When supported by the server and file format, you can start streaming immediately without downloading the entire file first. 【Broad Format Support】 Supports comic archives, documents, ebooks, and common image formats, including ZIP/CBZ, RAR/CBR, PDF, EPUB, MOBI/AZW/AZW3, JPG/JPEG, PNG, WEBP, GIF, HEIC/HEIF, BMP, TIFF/TIF, and SVG. No manual extraction or conversion is required—import a file and start reading. 【Open a Remote Library and Start Reading】 Connect to a computer, NAS, or remote library through SMB, WebDAV, or OPDS. Supported files are loaded on demand, so you can start reading without waiting for the entire comic to download—ideal for large collections. 【Multiple Ways to Import and Access】 Import individual files or entire folders from the Files app, or transfer comics to your local library over Wi‑Fi. You can also mount folders or connect to SMB, WebDAV, OPDS, and cloud storage to access local and remote collections in the way that works best for you. 【AI Image Enhancement】 Intelligently reduces blur and jagged edges in older comics for a more comfortable reading experience. 【A Reader Designed for Comics】 Adapts to manga, Western comics, and vertical-scroll comics with right-to-left, left-to-right, and vertical reading. Choose your preferred page transition and use two-page view, split spreads, edge cropping, and auto-read to make every session feel natural. 【Organize Your Local Library】 Manage your local collection with folders and tags. Search, sort, pin titles, and choose from multiple library layouts to find what you want quickly. Reading progress is saved automatically, so you can pick up where you left off. 【Keep Track of Every Reading Session】 View reading time, pages read, reading streaks, title rankings, and your reading calendar. Look back on your reading history and see every session add up. 【Create a Reading Space of Your Own】 Choose from multiple themes and display settings, and personalize your reading space with custom fonts and theme wallpapers.

FolderShelf

Folder Image Viewer lets you browse the PDFs and images you keep in folders — on your device or in the cloud — exactly as you filed them. WHEN IT HELPS • Technical PDFs and textbooks piling up in a folder, with no appetite for loading them into Books one volume at a time • Photos exported from a camera, still sorted into the folders you made • Scanned documents and drawings, opened per project • Reference images and design assets, grouped by category Photos organises by album, not by folder. Books wants each PDF registered individually. Neither will simply open a folder. This app does: pick one folder, and every PDF and image folder inside it lines up. Nothing is imported. WHAT MAKES IT DIFFERENT • Nothing is copied Your images are never imported into the app. They are read in place, from wherever they already live. No duplicate storage, and reorganising your folders is reflected immediately. • Your folder structure becomes the gallery Pick one source folder and the app finds every subfolder containing images and every PDF inside it, then lays them out one entry at a time. No adding them one by one. • PDFs open as they are A PDF in your folder becomes a single entry — one file, one volume. Nothing is converted and nothing is imported into the app. Open it and turn the pages. Because PDFs are read through the same viewer as image folders, zooming, two-up view, and resuming where you left off all work the same way. • Cloud friendly Alongside iCloud Drive, you can reference cloud services connected to the Files app. Only the cover is loaded up front; the rest download when you actually open a folder, so opening the gallery never triggers a flood of downloads. • Fast search Search folder names and file names together. Results come from an in-memory index rather than rescanning storage on every keystroke, so it stays quick as your collection grows. • A viewer that gets out of the way Controls stay hidden until you tap. Pinch to zoom, double-tap to reset, and switch to a two-up view when you want to compare side by side. • Pick up where you left off Your position is remembered per folder and shown in the gallery, so even a folder with hundreds of images opens where you stopped. • Sorting that behaves Order folders by number, name, or date. The order of images inside a folder always follows their file names, so sorting never scrambles their contents. • Three languages English, 日本語, and 简体中文, switchable at any time in Settings. SUPPORTED FORMATS Images: JPEG, PNG, WebP Documents: PDF PRICING Everything is free for 7 days after install. To keep using the app after that, a single one-time purchase unlocks it permanently. No subscriptions, ever. PLEASE NOTE • This is a viewer and includes no books or images of its own — only a few samples for trying it out. Please use your own files. • Password-protected PDFs are not supported. • Because of an iOS limitation, some cloud services (such as OneDrive and Box) cannot be browsed in folder-selection mode. For those, use "Add Files" to select image files directly instead.
