WordLab: Vocabulary Builder

Science-Based Learning System

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

WordLab pushes the frontier of vocabulary-building methodology. WordLab is the first app to systematically ensure your words leap to mind in the right contexts when you think, speak, and write. It offers true vocabulary expansion: words that once felt foreign truly become second nature. This is beyond rote memorization. To achieve this, WordLab combines 6 essential technical ingredients no app has combined before: 1. Active Recall. Without this you may learn to recognize a word when you read it, but you can't necessarily conjure it in mind even if you see the definition. You don't own it. 2. Spaced Repetition. This automates reviews, making it possible to learn and maintain memory of more and more words without increasing daily time spent. 3. Recall-Speed-Aware Scheduler. By informing the smart scheduler of every recall's speed, fast recall is unlocked sooner and failed recalls & wasted time are reduced. 4. Variable-Context cues. Only when the learned cues for recall mirror the real world do your words leap to mind reliably in real contexts while you think, speak, and write. 5. Contrastive Learning. Without this, clusters of words blend together in your mind so you can't tell them apart (e.g. amiable vs genial, dale vs glen vs dell, prudent vs judicious). Subtle flavors are pointless without a refined palate to appreciate them. 6. Words ordered by rarity. By learning words in order of rarity, you maximize utility gained per unit time spent in terms of recognizing words you'll actually see and that people will understand when you use. It is also natural that the more common a word is, the more useful it is likely to be, as a trend. Beyond these 6 essentials, WordLab includes extra ingredients that further optimize learning and encourage flow-state and habit-formation: 1. Each word has an image encoding its meaning. These evocative images get exposed upon each recall to be reinforced, leveraging the superiority of visual-spatial memory and acting as so-called "neural hooks" to improve retention and understanding in accordance with dual-coding theory. 2. With over 15,000 procured words, the app offers a comprehensive set of words so you have lots of room to grow. 3. Astral Trophy Room. Watch your vocabulary grow! Every learned word becomes a star in your explorable sky. Practiced contrasts form constellations. 4. Streaks encourage daily use 5. Achievements and Leaderboards encourage aspirations 6. Unlocking animal profile pictures described by your words allows you to personalize your profile further as you progress. 7. Save Word Collections to keep track of your favorite kinds of words 8. Play multiplayer with friends 9. Make separate profiles connected to your iCloud account so the whole family can play on all your devices. 10. Crosswords package up repetitions into palatable gamified bite-sized pieces 11. No ads! Don't get bothered by annoying ads! MAKE IT YOURS Explore a bank of about 20,000 English words. Save word collections, play multiplayer with friends, and use separate profiles on iPhone and iPad through your iCloud account. Choose reminders that fit your routine. Made for readers, writers, advanced English learners, and anyone who wants their word-game time to build a richer vocabulary using a cutting edge methodology.
