Tap it to add a book. If you select a category first, the book will be added to that category. To add a book to a specific bookshelf, choose “Select Bookshelf” or create a new one. For the title field, enter the book’s title. If a bookshelf is selected, enter only the volume number. (This is because searches are performed using the bookshelf name + title.) If you search for a book and select it, the details will be filled in automatically. If no bookshelf is selected, one will be created automatically. (If you select a category before adding a book, the bookshelf will be created within that category.) If you search without entering any keywords, the sales ranking will be displayed. Entering search conditions will show recommended results. The “+” button allows manual entry of books into the selected bookshelf. You can also search and register books using barcodes. When searching, selecting a bookshelf in advance enables bulk registration. Bulk registration via “Add” allows you to add multiple volumes at once, from a starting number to a specified number. ■ Adding Categories On the category screen, tap “Edit” and then tap “+” to add a category. You can also change category settings by selecting a category while editing. (Settings can also be changed via the long-press menu.) ■ Adding Bookshelves Selecting a category displays its bookshelves. Tap “Edit” and then the “+” button at the bottom to add a bookshelf. In list view, you can change bookshelf settings by selecting a bookshelf while editing. (Settings can also be changed via the long-press menu.)

While editing, you can perform bulk deletion and bulk category changes. ■ Bookshelf Settings ○ Management Type Comics For serialized comics. If a book title includes volume numbers, a bookshelf is created using the title name. All volumes are grouped under that bookshelf, and individual book names consist of the volume number only. Author For paperbacks and novels. If there is no volume number but an author is present, a bookshelf is created using the author’s name, and books are grouped under that author. Other All other books fall into this category. You can freely add books. ※ Bookshelves created via search follow the above rules. ※ If the option “Bookshelf name = title only” is enabled during search, books without volume numbers will be categorized as “Other.” ○ Completed Check this option for completed series to display a mark in the bookshelf list. ■ Book Settings You can change the book image from the icon in the top-right corner. Images obtained from albums or image searches are high resolution. Tapping the blue text for authors or publishers will search for related books. Wishlist and favorites are displayed in the category list. When a book is marked as a favorite, you can add ratings and reviews.

Verdict

Smooth Reader's advantage is ads (none vs shown). On in-app purchases and iOS requirement there is nothing between them.
