About this app
📚 Essential English — an English study room inside your phone, with no data worries
Install it and you are done. Your study records are kept safely on your phone only. No login, no sign-up.
⚠️ This app teaches English TO KOREAN SPEAKERS. Word meanings, explanations and the interface are all in Korean, so it is built for learners who read Korean.
■ WHO IT IS FOR
• Anyone who freezes when it is time to speak English
• Anyone who wants a little every day, without worrying about data
• Anyone who wants vocabulary, grammar and conversation in one app
■ KEY FEATURES
📖 22,000+ words and expressions — core vocabulary for Korean exams (수능 / TOEIC / TOEFL / business English), organized by level
🧩 Grammar quizzes — parts of speech, sentence patterns, prepositions, tenses, relative clauses
📊 Weakness analysis — your wrong answers collected into statistics so you review only what you are weak at
🗣 Listen and repeat with a pronunciation score — graded instantly by on-device speech recognition
🎯 Expression challenges and active-production quizzes — "here is the situation in Korean, now say it in English"
💬 Conversation — rich situational dialogues: school, dating, travel, hospital, job hunting, startups, social media
✍️ Writing practice — an on-device grammar check that catches the basic mistakes
📕 Read real books — download public-domain English books and tap a word to save it instantly
🃏 Vocabulary card practice — spaced repetition (Leitner) so the words stick, with focus on your weak ones
🔥 Earn gems from check-ins and streaks, then turn off interstitial ads
■ TWO TRACKS: RECOGNITION AND ACTIVE USE
Not just memorizing. Phrasal verbs and expressions push you to actually say them, turning words you know into words you use.
■ FREE / ADS
• Core study is completely free, with no in-app purchases
• Only a small banner is always on; interstitials can be turned off with gems, or removed for a week with a single rewarded view
• Ads are set to a General (G) content rating
■ WORKS OFFLINE
Everything runs on the device with no internet connection. Study records are never sent to a server — they stay on your phone.
Install it now and build your English a little every day.
