◆InstaEnglish – Turn Words into Real Conversations InstaEnglish is the ultimate app for building real-world English skills through instant sentence translation practice. Whether you’re aiming to speak fluently at work, while traveling, or in daily conversations, InstaEnglish helps you grow the English vocabulary you can actually use. ◆What You Can Do with InstaEnglish 1. Practice Real-Life Scenarios Choose from a wide range of practical situations—from business meetings to shopping trips—and instantly translate useful Japanese phrases into English. Practice with sentences that you’ll actually use. 2. Get Instant Feedback on Your Answers There’s more than one “correct” way to say things! InstaEnglish gives you immediate, personalized feedback to help you learn and improve right away. 3. Grow Your Active Vocabulary We automatically track the English words you use correctly and count them as part of your Active Vocabulary. Aim to master the 2,000 most essential words for daily conversation—fast. 4. Measure Your Speaking Speed Automatically InstaEnglish tracks how fast you speak (in words per minute, or WPM). Work toward a natural, fluent speaking pace of 150 WPM—the sweet spot for native-level communication. ◆For Learners Who Struggle to Speak Have you ever thought: “I’ve studied grammar and vocabulary, but I freeze when I try to speak…” “I’ve taken so many English lessons, but I still don’t feel confident…” InstaEnglish is made for learners just like you. Our proven method helps you turn passive vocabulary (words you know) into active vocabulary (words you can actually use in conversation). ◆What Is “Active Vocabulary”? Active Vocabulary refers to the words you can confidently and correctly use in real conversation. Even if you’ve learned a word, if you can’t recall and use it while speaking, it stays in your Passive Vocabulary. InstaEnglish is designed to train learners who already know around 2,000 basic English words to turn them into active, usable language. ◆Why Focus on 2,000 Words? Studies show that about 90% of everyday English conversations can be handled with just 2,000 commonly used words. That’s why our learning materials are optimized around these essential building blocks. ◆How Do We Measure Speaking Speed? For every correct answer, InstaEnglish automatically records the time it took you to respond. Using that data, it calculates your Words Per Minute (WPM) so you can track your average speed and progress toward fluent, native-like communication. ◆Why Instant Sentence Translation Works To speak a language, your brain goes through 3 steps: 1. Create an idea 2. Convert it into words 3. Say it out loud InstaEnglish removes Step 1 by giving you the idea in your native language. That way, you can focus entirely on Step 2: turning thoughts into English. This makes it one of the most efficient ways to train your brain to speak naturally and quickly. ========== ◆ Frequently Asked Questions (FAQ) Q: How is InstaEnglish different from other English learning apps? A: InstaEnglish is built around the "Instant English Translation" method, focusing entirely on enabling you to instantly use words you already know. The app incorporates a scientific approach to efficiently improve English speaking skills, guided by top US linguists serving as advisors. This has earned the trust of many learners. While typical English schools and apps use free-speaking formats with high flexibility in "what" to say, InstaEnglish provides the "what to say" prompts, allowing learners to concentrate solely on "how to express it in English." Q: Is it free? What are the plans? A: Free to download, and some lessons are free to use. The Standard plan unlocks all 12,000+ prompts; the Premium plan adds pronunciation feedback. Both are monthly or annual, and annual plans include a 7-day free trial. See In-App Purchases on this page for prices. Q: Which devices are supported? A: iPhone and iPad. No Android or web version.
