Know your way around the Bible. MemoryU helps you learn where every passage is found in Scripture. Rather than memorizing verses word for word, you learn to recognize a story or teaching and recall exactly where it lives — its book, chapter, and verse — until you can navigate all 66 books with confidence. Each card presents a passage by its title or theme, and you recall its reference, then check yourself. Over time the layout of Scripture becomes second nature: you will know that the Parable of the Sower is in Matthew 13, and where to find the Beatitudes, the Ten Commandments, or the letters of Paul. HOW IT WORKS • See a passage, recall where it is located, and grade your answer • Spaced repetition schedules each card for review at the right moment, so what you learn stays learned • Three study modes: reveal the answer, ask for a hint, or type the reference STUDY ANY WAY YOU LIKE • By book — all 66, Genesis to Revelation • By section — the Torah, the Gospels, the Prophets, the Epistles, and more • By theme — Parables, Miracles, Famous Prayers, Messianic Prophecies, Covenants, and others • Curated collections such as "Life of Jesus," "Greatest Stories," and "Prophecy Fulfilled" • Custom decks you build yourself, with your own titles, colors, and icons STAY ON TRACK • Set a daily goal and an optional daily reminder at a time you choose • Follow your progress book by book as your knowledge of Scripture grows • Passages you miss are saved to your Mistake Vault to review until mastered • Star passages you want to revisit for quick access BUILT FOR EVERYONE • Sign in with Apple or email, or try it first as a guest • A clean, distraction-free design that keeps the focus on learning • Adjustable sound and haptics Whether you are new to the Bible or deepening a lifelong study, MemoryU helps you build a lasting, navigable knowledge of Scripture — one passage at a time.
