About IELTS Vocabulary 4000
Your IELTS vocabulary, always in your pocket. For anyone aiming for a target IELTS band score, planning to study at a university or graduate school abroad, or building the vocabulary to read academic papers and news in English. Covers 4,000 high-frequency academic words for IELTS Band 5.0-7.5+ — with audio on every word and example sentence. [Sources] ▶ Exam data · Official IELTS sample questions ▶ Vocabulary lists · NGSL (New General Service List 1.2, 2,801 general high-frequency words) · AWL (Academic Word List, Coxhead 2000, 570 core academic families) · NAWL (New Academic Word List 1.0, 963 families) · AVL (Academic Vocabulary List, Gardner & Davies 2014) ▶ Corpus frequency · COCA Academic (Corpus of Contemporary American English, Academic Sub-corpus) · JACET 8000 (Japanese-learner baseline, used to subtract already-known high-frequency words) These data sources were statistically combined — subtracting high-frequency words already known to Japanese learners — to select the 4,000 academic words most frequently required by IELTS. [Learning features] ■ Audio on every word and example sentence Hear natural native English pronunciation for every word and every example sentence, so you learn the sound along with the meaning. ■ Background Listening (plays while your screen is off) Stream words continuously and keep learning on your commute, during chores, or at the gym — even with the screen locked. ■ Hide-to-memorize Tap to hide the translation, then reveal it to check yourself. Faster than a flashcard, works one-handed. ■ Shuffle Randomize the word order so you are testing real recall, not memorizing a sequence. ■ 6 translation languages Switch the translation language anytime — Japanese, Vietnamese, Chinese (Simplified), Korean, Indonesian, and Thai. Translations and translation audio included. ■ Two-way display toggle Switch between English → translation and translation → English to practice both recognition and production. ■ Synonyms, antonyms, and related words Each word card shows related vocabulary to build a richer mental network. ■ Filtered review Check off words you have learned and filter to the unchecked ones. Also filter by band, part of speech, or keyword. ■ Offline After downloading, no internet required. Works on the subway, on planes, anywhere. ■ iPad layout Optimized for larger screens so iPad users get the same polished experience. [Plans] Free : 414 words (IELTS Band 5.0-5.5) Plus : 1,915 words (IELTS Band 5.0-6.5) Pro : 4,000 words (IELTS Band 5.0-7.5+, full range) Start free with the complete Band 5.0-5.5 level. Add the bands you need when you are ready to go further. * Contents are subject to change without notice.
