Kawan EPT is an Android app from Kubiku Technology for TOEFL® ITP practice: 7,400+ questions with explanations for every answer option, 1,000 Listening audio tracks, a 3-section simulation with a score estimate of 310–677, Grammar, Reading, and Listening lessons, and 1,800 academic vocabulary words. Before version 1.12.0 (October 2026) the app was named Kawan TOEFL. TOEFL® and TOEFL ITP® are registered trademarks of ETS; Kawan EPT is not affiliated with or endorsed by ETS.

Kawan TOEFL is now called Kawan EPT. It is the same app; only the name changed, starting with version 1.12.0 (October 2026). The Google Play link has not changed: search for "Kawan EPT" on Google Play, or update the app if Kawan TOEFL is already installed on your phone.

No. Your questions, practice progress, history, and subscription stay safe. Kawan TOEFL Pro is now Kawan EPT Pro and stays active without subscribing again.

Kawan EPT is designed for the TOEFL PBT and TOEFL ITP. It covers the three main sections, Listening Comprehension, Structure and Written Expression, and Reading Comprehension, with score predictions from 310 to 677.

TOEFL PBT and ITP are paper-based with three sections: Listening, Structure & Written Expression, and Reading. TOEFL iBT is internet-based and adds Speaking and Writing. Kawan EPT focuses on TOEFL PBT and ITP.

Yes. Start with the 15-question Diagnostic Test to map your weak spots, then study from the Learn or Lesson level before practicing. Vocabulary flashcards are also split into Easy, Intermediate, and Advanced.

There are three types of material: 33 Grammar topics, 11 Reading Strategies, and 7 Listening Strategies with audio, plus 1,800 academic vocabulary words in interactive flashcards.

Yes. Kawan EPT simulations follow the TOEFL ITP format and section order with graduated difficulty.

Kawan EPT estimates your total TOEFL PBT score (310–677) and section scores (31–67) from your average practice performance. It is an estimate for tracking progress, not an official score.

It's flexible. 3-in-1 Lightning Practice is only 15 questions (5 Listening, 5 Structure, 5 Reading), section practice lets you choose the number of questions, and full timed simulations are there when you're ready to test yourself.

Kawan EPT uses the SM-2 Spaced Repetition algorithm. Questions you often get wrong appear more frequently, while mastered questions are rescheduled at increasingly longer intervals. Weakness Drill also prioritizes the categories you miss most.

Yes. All questions and Listening audio are bundled inside the app, so practice and simulations work without an internet connection. Internet is only needed for online features such as Google account sync.

The free version is supported by ads so development can continue. Kawan EPT Pro is an optional subscription for a 100% ad-free experience and longer practice and simulation history.

Yes. Sign in with Google to back up your progress to the cloud. Sign in with the same account on another device and your progress syncs over.

Yes. Kawan EPT can create a Score Report with your simulation score in portrait or landscape that you can download as a PNG or share directly to social media.

Yes: configurable study reminders, a 2x1 home screen widget to track your streak, and light, dark, or system themes.

Kawan CPNS covers the full Seleksi Kompetensi Dasar (SKD) for Indonesian civil service candidates: Tes Wawasan Kebangsaan (TWK), Tes Inteligensi Umum (TIU), and Tes Karakteristik Pribadi (TKP), with 6,200 questions across 14 sub-categories.

Yes. Simulations have 110 questions in 100 minutes in the TKP, TIU, TWK order used by the CAT system. Simulation sets never repeat questions from your last 3 simulations.

TWK and TIU questions are worth 5 points when correct, while each TKP option is weighted 1 to 5. Kawan CPNS calculates scores per category and predicts passing based on the general thresholds: TWK 65, TIU 80, and TKP 166.

Yes. Of Kawan CPNS's 6,200 questions, 400 are figural picture questions for practicing visual reasoning in TIU.

Yes. There is material for every sub-category with quizzes and Mastery Mode, plus 555 SKD flashcards and an adaptive weekly study plan.

Kawan CPNS uses SM-2 Spaced Repetition. Each practice session mixes about 70% new questions, 20% questions due for review, and 10% weak questions. Automatic Remedial Mode helps you fix categories that still need work.

Yes. Save up to 50 favorite questions, add personal notes up to 500 characters, and use quick tags such as Quick Formula, Review Again, or Trick Question.

Yes: configurable study reminders, a home screen widget to track your streak, and light, dark, or system themes.

Kawan CPNS is designed to be lightweight and runs on Android 8.0 and up.

Kawan Vocab is an English vocabulary app for Indonesian speakers with 6,000 words across 6 stages and 24 themed levels. Every word comes with a contextual Indonesian meaning and an everyday example sentence.

Every level, from everyday basics (CEFR A1) to professional and academic vocabulary (CEFR C2). Take the 18-question placement test to start at the right stage.

Kawan Vocab uses spaced repetition: words come back right before you start to forget them, after 1, 3, 7, 14, 30 days, then keep doubling. A wrong answer does not reset your progress to zero, it only drops one step.

About 10 minutes. Each session has 5 new words and up to 15 review words, plus one correction round for words you missed.

There are 4: pick the right meaning, pick the right English word, fill in the sentence (cloze), and type the word from memory (active recall).

Yes. Hear each word and example sentence with one tap, at a speed that is easy to repeat.

The next level unlocks once you have studied 85% of the words in the previous level. To move up a stage, pass the Stage Challenge with at least 80%.

No. Kawan Vocab works 100% offline with no sign-in. All vocabulary and your learning progress are stored on your device.
