When useful, turn on automatic audio playback to repeat key terms while walking, resting, or preparing for sleep without continuously reading the screen.

Know whether a book is right for your child before they open it. Scan the cover and ReadRabbit identifies the book, scores its difficulty on the same 0-1400 scale as your reader, and tells you plainly: too easy, too hard, or just right. Then it keeps the log, so you can see the year add up. SCAN A BOOK, GET ITS LEVEL Point the camera at a cover or a barcode. In a few seconds you get the title, the author, the reading level, and whether it fits the child you are shopping for. It works in the bookstore aisle, at the library, and on the shelf at home. A READING LOG THAT TAKES ONE TAP Log the day's reading and the streak grows. Set a daily goal, earn bronze through platinum challenges, and keep a real history for each reader. Books move through Reading, Up Next, Paused, and Finished on a shelf that belongs to that child alone. THE NEXT BOOK, ALREADY PICKED Browse by grade, by age, or by what your child actually likes: fantasy, mystery, sports, funny, animals. Hand-picked lists cover Newbery and Caldecott winners, bestsellers, new releases, summer reading, and a back to school list of 140 titles from Pre-K through 12th grade. Every pick is matched to the reading level, not just to what is selling. BORROW IT FREE Choose your public library once and every book gets a borrow link, straight into your library's catalog and Libby. Check the shelf before you buy. MORE THAN A TRACKER Comprehension quizzes and flashcards built from the actual book your child is reading. Vocabulary Spotlight pulls the words worth learning. Writing Workshop gives book-specific prompts, and you can photograph the finished handwriting for warm, kid-friendly feedback. WHAT YOU SEE AS A PARENT Reading minutes, books finished, quiz scores, and reading level growth over time. Pro families get a progress report by email on the first of every month, which is a nice thing to have when a teacher conference comes around. BUILT FOR A FAMILY, NOT A CLASSROOM Add a profile for each child with their own grade, level, and library. Invite a co-parent and you both see the same log. Grades move up automatically every September 1, so you are not editing profiles at the start of a school year. Grown-ups create and control every profile. Children never sign in, and we do not store the photos you scan. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://readrabbit.co/privacy
