The Shelf Is a Special Notebook for All Your Thoughts on Books.
iPhone: Taking notes as you read a book is a great way to solidify thoughts in your mind and explore various theories about what you are reading. While you can do this in any note-taking app, Shelf is all about books and has some features that make it useful for just that.
What makes Shelf beautiful is its built-in book search engine. Find the title of the book and you get a nice big image. When you add it to your collection, you can add as many notes about this book as you like. It’s a super-simple little thing, but if you read a lot and want a dedicated note-taking app to jot down your thoughts, Shelf is worth taking a look at.
