Free · Designed for iPad. Not verified for macOS.
Now with customizable quizzes, color-coded and tagged flashcard sets, and smarter word search — study your way, right from your own vocabulary.
Lexicon Vocab Builder helps you learn, retain, and actually use new vocabulary — through daily words, custom flashcards, and quizzes built from your own study sets.
Whether you're expanding your everyday vocabulary or building toward the kind of words that show up on the GRE, SAT, or TOEFL, Lexicon gives you a simple, focused way to study.
KEY FEATURES
Word of the Day — Learn one new word each day, with adjustable frequency to match your pace.
Custom Flashcard Sets — Build your own sets, organize them with color and tags, and search across everything you've created.
Quizzes From Your Own Words — Turn any flashcard set into a quiz. Choose from multiple question types, timed or untimed, and study the way that works for you.
Favorites & Known Words — Keep track of the words you want to revisit and the ones you've already mastered.
Add Your Own Words — Create custom word entries with your own definitions whenever the built-in dictionary doesn't have exactly what you need.

Lexicon Vocab Builder is a focused tool for building real vocabulary, one word and one quiz at a time.
Some features are available through an optional in-app purchase.
