Vocabulary that grows with you

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Grow a living brain of every word. Rate a word, watch it take root, and keep it for good. What's That Word Mean is a vocabulary app built to make words actually stick, not just cram them for a test and forget them a week later. Rate a word, watch it take root in your living brain, and keep it with gentle spaced review that resurfaces words right before you'd forget them. It's calm, visual, and a little bit alive. WHAT'S INSIDE • A living brain: every word you learn takes root in a visual brain that grows as you do. • Know how a word lands: see a word's connotation charted from negative to positive. "Stubborn" and "tenacious" mean nearly the same thing, but land completely differently. Learn to use words right, not just know them. • Prove you really know it: use a word in your own sentence and get instant, thoughtful feedback. Recall is how words truly stick. • Words that stick: gentle spaced review brings words back right before they fade. • Five levels, your pace: from everyday words to advanced. Every word is tuned to your level, so it's never too easy or too hard. • Illustrated word packs: themed collections hosted by Lex and W. Smith, from Feelings & Moods to Power & Persuasion, where every word comes with its own illustration. • A word a day: a fresh Word of the Day every morning, with a streak to keep and a home-screen widget so a new word finds you. FREE TO START Look up any word, grow your brain, and build a daily habit for free. Upgrade anytime to unlock deeper study: spaced review across your words, more decay lists and study decks, the full illustrated pack library, and more Guesser plays. Meet Lex the cat and W. Smith the fox, and learn words in a way that feels calm, not like a chore. Download What's That Word Mean and start growing your vocabulary today.
