It's built so that simply looking at your own shelf feels good. ■ Add a book with one search, or a quick scan ・Search by title, author or ISBN. The cover, publisher, release date and description fill themselves in ・Point the camera at the barcode on the back of a book and add it on the spot ・Tap + on a search result. Select several and add them all at once ・Duplicate checking, so the same book never lands twice ■ Your shelf ・Switch between a grid of covers and a list that shows more detail ・Filter by Want to read / To read / Reading / Finished ・Search across tags, authors, series, publishers — even the text of your memos ・Sort by date added, title, author, series or rating ・Group a series into one stack (volume one in front, with a count badge) ・Select several books and change their tags, series or status together ・Books you're reading show a progress bar under the cover ■ Inside a book ・Edit the title, author, publisher, status, rating, start and finish dates, series, tags and memos right there ・Mark one finished and a bookmark slips into the cover — a small moment worth having ・A five-star rating and a place for your thoughts ・As many memos as you like.
