Frustrated in your search for book apps inside the Apple App Store? The online OttoCat tool will help you explore the subcategories in a simpler interface.
Follow this link to browse by “Book” and filter by a wide variety of subcategories. AppNewser has all the details:
To help users discover new apps, tech start-up OttoCat has created the OttoCat Taxonomy Browsing Platform, a new app discovery platform. The tool lets consumers shop multiple layers of the App Store. On its own, the App Store features 23 categories to shop from. OttoCat extends this and creates new subcategories based on a user’s search, so that shoppers can go much deeper. For example, you can start with the Entertainment category, click to “Comics,” then drill down to “Manga,” “Graphic Novels,” “Super Hero,” “Comic Con,” and “Humor,” among about 20 other subcategories.
