About

BookDrawer

Read full description

BookDrawer is a quiet drawer for the books you keep. When you read them, how many times, and where they are now — all in one place. ■ Library — Want to read, reading, finished. And bought, borrowed, given away. ■ Reading history — Read it again and each pass keeps its own dates, rating, and notes. ■ Your shelf — Owned, to buy, departed (gifted, sold, lost). Two copies of one book, tracked separately. ■ Quotes — Photograph a passage and the words come across on their own. Page numbers too. ■ Reading calendar — Covers of finished books fill in the calendar, and turn into share cards for your feed. ■ iCloud sync — The same library on iPhone, iPad, and Mac. No sign-in. ■ Book search — Find by title or author and pull in the cover and details. (Book data: Google Books) No ads. Just your books.
