Learn the books of the Bible the way that actually sticks. Book by Book helps you memorize the names and order of all 66 books, from Genesis to Revelation, through three simple modes that build on each other. STUDY Scroll a clean, distraction-free list of all 66 books in canonical order. No verses, no chapters, just the names and the order, separated by testament. PRACTICE The full list appears with some books hidden. Fill each blank by choosing from six options. Correct answers lock in green; miss one and the right answer is revealed so you learn as you go. Three difficulty levels change how much is hidden: -Easy: a third of the books are blank -Medium: half are blank -Hard: the entire list is blank The hidden books are randomized every round, so no two attempts are ever the same. TEST The final exam: 66 empty blanks, type every book from memory. Nothing is graded until you submit, then you get your score and corrections for every miss. Smart matching accepts natural variations like "1st Samuel," "First Samuel," or "Psalm," and autofill suggestions cut down on typing without giving answers away. PROGRESS Track your day streak, session history, best scores per mode and difficulty, a trend chart of recent scores, and the books you miss most often, so you know exactly what to review. MORE Works completely offline No account, no sign-up No ads, no tracking; progress is stored only on your device Great for kids, Sunday school, Bible quizzing teams, and anyone who wants the order down cold Whether you're brand new to the Bible or just tired of hunting through the table of contents, a few minutes a day is all it takes.
