About Kawan Vocab
Kawan Vocab is an Android app for Indonesian speakers who want to master English words and expressions in a structured way, from everyday basics (CEFR A1) to professional and academic vocabulary (CEFR C2).
About 10 minutes a day is enough. Every session mixes new words with older words that are due for review, and the app decides when each word should come back. The whole curriculum and your progress live on your device, so it works 100% offline with no sign-in.
It suits high school students, university students, workers, job seekers, and anyone preparing for TOEFL® or IELTS.
Key Features
6,000 Curated Words
A curriculum of 6 difficulty stages and 24 themed levels, from “Home & everyday objects” all the way to academic terminology. Every word comes with a contextual Indonesian meaning, part of speech (noun, verb, adjective, phrase), and an everyday example sentence.
Interactive Study Cards
- Flip Cards: Tap to flip between the English word and its meaning.
- Pronunciation Audio: Hear each word and example sentence with one tap, at a speed that is easy to repeat.
- Word Collection: Save hard words and practice them again anytime from the Collection tab.
Smart Review (Spaced Repetition)
Words come back right before you start to forget them. Review intervals grow as you improve: 1, 3, 7, 14, 30 days, then keep doubling. Each word moves through 5 mastery stages: New, Learning, Familiar, Remembering, and Mastered.
A wrong answer does not reset your progress to zero. Kawan Vocab uses a soft penalty: mastery drops by just one step, so learning stays fair and frustration-free.
Balanced Sessions: New Words + Review
Each session has 5 new words and up to 15 review words, so you keep moving forward even when reviews pile up. Miss a question and you get one correction round before the session ends. Extra review sessions are available when the queue gets long.
4 Practice Types
- Pick the right meaning for an English word.
- Pick the English word from its Indonesian meaning.
- Fill in the sentence (cloze) using context clues.
- Type from memory (active recall) to strengthen long-term retention.
Answer choices are filtered so confusing synonyms never show up together.
