Memorize anything made of words. Scripts, monologues, speeches, wedding vows, toasts, lyrics, poems, prayers, recipes, interview answers. If it is written down, MemoryLab will get it into your head, and it will tell you honestly how much of it is in there. THREE LEVELS, ONE PIECE AT A TIME Level 1, Read and Listen. The text is performed aloud to you, voice by voice, so a script sounds like a scene instead of a page. The words light as they are spoken and the page follows along. Frame any passage with your finger and loop it until it sticks. Level 2, Type Over. The whole text in front of you. Read it, hear it, type over it. See it, say it, write it. Level 3, Fading Blanks. Words start disappearing by type. Take out the nouns, then the verbs, then the adjectives, and fill the gaps by typing or out loud. Hide every word and you are reciting the whole thing from memory on an empty page. Every word you get right draws itself in green, every miss turns red and shows you what you missed, and at the end you get your score with a map of what to review. Then you chase 100 percent. IN YOUR OWN VOICE Read a document into the app and play it back at any pace, looped, with the words lighting as you say them. Level 3 can ask each question in your voice. FLASHCARD DECKS Terms, dates, names, anything that comes in pairs. Study a shuffled batch, sort each card into Got It or Needs Work, then rematch the misses. Record your voice on either side. Multiple choice too. SPELLING TESTS See the word or hear it only, then type it or say it back letter by letter. The real thing, without the parent having to read the list out loud. MATH DECKS Multiplication, division, addition and subtraction, with a number keypad instead of a keyboard, worked steps on the page, the problem read aloud, and Mad Minute when it is time to go fast. EVERYTHING STAYS ON YOUR PHONE There is no server. There is no account to make. There is no AI. The practice, the scoring, the speech recognition, and the camera import all run on your device, so MemoryLab works with no signal at all: on a plane, or in a basement. Your documents are yours. Nothing is uploaded and no one else can see them, which matters if what you are learning is not yours to share yet. GET YOUR TEXT IN Type it, paste it, dictate it, or photograph it. Camera and PDF import turn a page into editable text on the device. Hand a document to another MemoryLab. YOUR LAB Shelves of documents on twenty one scenes, reordered by hand and searchable, with a Home Screen widget. Full iPad layouts. THREE DAYS FREE, THEN READ FOR FREE The complete Hamlet act by act, twenty seven Shakespeare monologues, speeches from Lincoln and Kennedy and Douglass, verses and prayers, poems and rhymes, and study decks all ship with the app and stay readable for nothing, always. For your first three days everything works, no card needed. After that the practice itself, the recording, the reading aloud and the tests, opens with Full Access: yearly at $34.99 or weekly at $6.99, each starting with a 3-day free trial, or one lifetime purchase of $99.99. THE STORE Italian, French, Spanish and Portuguese: each one 20 areas of life, more than ten thousand cards. Kindergarten is free in full in every language, and you can try 20 cards a day from every other deck. One purchase unlocks a module permanently. BUILT FOR Law Students, Actors, students, parents and teachers, public speakers, musicians, brides and grooms and best men, language learners, and anyone keeping their mind sharp. A NOTE ON SCORES Your phone's speech recognition does the listening, and accents, background noise and old fashioned words can all stop it hearing you correctly. A score is practice feedback, never a measure of how well you know your piece. When it mishears a word you know you said, you can overrule it.
