Otaku Shelf - the app for your collection of books, manga and comics You know the feeling. You are standing in the shop thinking: "Do I already have volume 4, or was that volume 3?" Or: "Is that the novel already sitting on my shelf, just with a new cover?" That is exactly what Otaku Shelf is for: your collection comes along, and questions like that have an answer straight away. ▬ Whatever you collect A wall of novels or a shelf of manga - Otaku Shelf is at home in both worlds. On first launch you tell the app what you collect: novels, manga, comics or all of it. It sets itself up accordingly and only hands you the tools your collection actually needs. You can change that at any time, every setting on its own. ▬ What is waiting for you A fast scanner: scan the ISBN, done. Several volumes in a row, too. Older books without a barcode are read straight off the cover by text recognition. Novel, non-fiction, manga, light novel, comic or audiobook - it all goes on the same shelf. Real catalogue data: Otaku Shelf queries national libraries and open book databases - English, German, French, Italian and Japanese titles included. A real shelf view with spines: no more endless, boring lists. Your collection stands there like it does in your room. Plus grid view, list view and series view. ▬ What our novel readers care about What else has this author written? Tap the author's name and you see the rest of their work - without the titles already in your collection. That way you find the gaps in the bibliography, not just the ones on your shelf. Reading progress: read, reading, paused or abandoned. With page count, reading diary and a yearly goal. Your reading stats: publishers, decades, genres, pages read and a year in review. ▬ Especially for manga and comic collectors Missing volumes at a glance: Otaku Shelf recognizes connected series and shows you straight away which volume you still need. New releases in view: follow your series and get a reminder when the next volume is due. Series view with collecting progress: for every series you also see how far its anime adaptation has got, if there is one. ▬ Your collection, day to day • A wishlist for your next trip to the shop or convention • Lent out and borrowed: who has your book? And who owns the one sitting on your shelf? • Easy move-in: import from Goodreads, The StoryGraph and Scanolino, or from any spreadsheet with an ISBN column. The app fills in the rest online. • Export as a PDF catalogue, shopping list, value report, spreadsheet or text list • Sync through your own cloud: iCloud, Google Drive, Dropbox or OneDrive, plus backups as a ZIP file • Widgets and Control Center actions: current book, upcoming releases and quick scan • 17 themes, dark mode and a few minigames played with your own covers ▬ What you will not find here No ads. No sign-up. No account. Your collection lives on your device and is there offline. Premium is a one-time purchase rather than a subscription and unlocks additional designs and extras. The collection itself is never capped. ▬ Who is Otaku Shelf for? For readers, manga collectors, comic lovers and anyone proud of their shelf, whether that is 30 volumes or 3000. A tracker that catalogues your library instead of turning it into list-keeping homework. Built by fans, for fans. Otaku Shelf is available in English, German, French, Italian and Japanese. Feedback is welcome: the feedback board inside the app lets you submit wishes and vote on other users' ideas.

Verdict
The clearest difference is in-app purchases: ECornerApp at none against Otaku Shelf's 3. ECornerApp also leads on iOS requirement (11.0 vs 26.0). Otaku Shelf's advantage is update cadence (every 8 days vs every 12 months). On price, ads and device support there is nothing between them.
