About

Vocabular

Features
Read full description

Most vocabulary apps make you study word lists. Vocabular works differently β€” you build your vocabulary from content you actually read. Open any website in the Read tab, tap any word, and instantly see its translation. Save it to your Library with one tap. The word is stored with its original sentence, so you always remember the context. Use the free Chrome extension to do the same while browsing on your computer. Everything syncs to the app automatically. When it's time to review, Vocabular's flashcard system shows you the words you're most likely to forget. Rate each word as Hard, Medium, or Easy β€” and Vocabular schedules your next review so you stay on top of what you've learned. Track your daily streak, mastery progress, and words due for review in the Stats tab. The result: vocabulary you actually remember, built from content you actually enjoy.
