This app is amazing!! The free version is insane!!!!! You can add unlimited books (?) I’m up to 600 and I see no limit in sight 😂 The paid version is literally just graphs and data that you get, I personally see no value in it, but you do you! You can add books to your TBR, to your Just Read, or to your Started pile. There are many ways to add your books. Either you can scan the barcode on the back, search up the title name and author to find it, or you can manually type in the book if you are that type of person. You can also scan many books at a times, you just have to select the option. When scanned, searched, or inputted manually, there is a book blurb given for each book and where to buy it, along with book genre details and other stuff. You can also create different “piles” or folders of books that can edit with ease. I personally like to organize my books into genre with these folders. The app is a BREEZE to navigate and this app truly is the best out there for FREE! I have seen and used many apps to keep track of which books I have, and all have had flaws. Either I had too many books, or I couldn’t search up the books I already had, or some other flaw that made me unable to use the app. But this app has zero, and I personally challenge you to find one
