Yes! Try Scholastic Book Wizard. It's free! I was using it just today. The only downside is that your books must have a bar code on them. The app will scan the bar code, then give you a brief synopsis of the book as well as a reading level. The reading level might be DRA, Lexile, grade level, or all three (depending on the book). It also lets you create book lists for keeping track of the titles you have once you've scanned the book. Many of my older books don't have a bar code, so I can't scan those, although there is an option to type in the title of the book if you can't scan it. Good luck!
