Memorize helps you truly learn the passages that matter — Bible verses, catechism answers, poems, quotes, or anything else you want to know by heart. Start by pasting a passage or typing one in. Then practice with as much or as little help as you need: • ENTIRE TEXT — read it until it's familiar • FIRST LETTERS — see just the first letter of each word as a prompt • HALF THE WORDS — first letters for a random half, blanks for the rest • FIRST + LAST — only the opening and closing words • BLANKS ONLY — one blank per word, all from memory • TYPE IT — type the passage and get instant word-by-word feedback, with optional hints when you're stuck Add a picture to any item — a photo of the page, a memory-book illustration, or anything that jogs your memory — and show it alongside any practice mode. EASY, MEDIUM, HARD Three presets let you dial difficulty up as you improve, and any item can keep its own custom settings. One tap returns everything to the session preset. ORGANIZE AND SHARE Group passages into lists, tag them (Sunday School, AWANA, family devotions…), and reorder them however you like. Share a whole list as a file that another Memorize user can import — perfect for teachers and parents. TRACK PROGRESS See how many times you've typed each passage correctly and which words trip you up most. PRIVATE BY DESIGN Your lists live on your device and sync through your personal iCloud account. No accounts to create, no ads, no tracking. "Thy word have I hid in mine heart…" — Psalm 119:11
