Wordbook for GRE® Test

Build the vocabulary to read demanding academic prose with a sharper sense of meaning, tone, and nuance.

Wordbook for GRE® Test is an independent study app with 3,456 distinct headwords and 3,514 reviewed meanings. Explore English definitions, parts of speech, and examples across Level 1 Foundation, Level 2 Core, Level 3 Advanced, and a separate Math terms collection. Math includes 226 headwords covering arithmetic, algebra, data interpretation, and geometry. The levels are study groupings, not official exam score bands.

From Today, start a Quiz with up to 20 contextual four-choice questions about new and familiar words. Choose All vocabulary, Foundation, Core, Advanced, or Math terms. Read the word and example, then choose the meaning that fits.

Review studied words in Random or Scheduled mode. Reveal an answer, then rate your recall Again, Hard, Good, or Easy to set the next review interval. Search by word or definition, filter by category or difficulty, save Favorites, mark words Known, organize lists, and add My terms. Track your learning in Progress and choose System, Light, or Dark appearance.

Applied practice includes 10 original context-completion questions and 10 equivalent-meaning questions. Equivalent-meaning questions require two answers. Every question includes an explanation. Revisit errors from Applied practice in Mistakes. These exercises are separate from Quiz. The app contains no official exam questions and does not promise a score.

Pronunciation uses Android system text-to-speech and requires compatible offline English voice data installed on your device. Listen to words and examples; available voices and accents depend on your speech engine and installed voice data. Included definitions and examples are available offline. Learning screens, definitions, and examples are in English.

Progress is stored on your device. Manually export a JSON progress backup and import it into the same Wordbook product. Review the import preview, then explicitly choose whether to replace the current progress. The app does not automatically sync progress between devices.

This is a separate paid download with no ads, account, subscription, or additional in-app purchase. The collection includes original Wordbook content and selected licensed Open English WordNet 2025 material. Credits are available in the app.
