Absolutely. English Core isn’t about cramming vocabulary or grammar—it’s designed to help you naturally learn English through experiences. You can start with simple phrases and conversations. Interactions with creators focus on expressions directly applicable to daily life. Even if you’re not confident in English, you’ll gradually gain the confidence to speak.

You can start learning effectively with just 5 minutes a day. Each unit is short, so you can easily fit it into spare moments or before bed. Over time, you’ll naturally develop the habit of engaging with English as part of your daily life, rather than just “setting aside study time.” Even busy people can steadily build listening and speaking skills through daily consistency.

Results vary from person to person, but some learners start noticing changes in just 1–2 weeks, such as “I can understand more sounds” or “I’m getting used to the rhythm of English.” English Core focuses on improving your English responsiveness rather than test scores, so you gradually become able to keep up with natural-speed English. Keep at it, and you'll gain confidence in real English exchanges.

With English Core, you practice using expressions at a pace close to real conversations. AI scoring lets you objectively check your pronunciation, fluency, and response speed, so you can train your conversational instincts, not just memorize words. Start with short responses and enjoy the process of gradually being able to reply naturally.

Yes, you can record your voice and get AI feedback on your accuracy and rhythm. This makes it easy to see which sounds you’re getting right. You can repeatedly practice difficult pronunciations, making it ideal for developing natural pronunciation.

Currently, the app is only available for iOS. We’ve received many requests for an Android version and are actively considering its release in the future. For the latest updates, please check our official website and social media channels.

English Core focuses on natural phrases used in real conversations, rather than textbook English. You can learn through authentic interactions in daily life, travel, cafes, social media, business settings, and more. With plenty of expressive and commonly used native expressions, you’ll develop practical English skills that you can actually use in your day-to-day life.

In the app, you’ll find videos featuring creators speaking English. By responding and pronouncing lines with your own voice, you can experience what it feels like to actually have a conversation with them. Rather than just listening, you train your English responsiveness through real “conversational back-and-forth.” It’s a new way of learning that’s like stepping into the video and speaking for yourself.

Many of the creators are native English speakers. You can experience real English that doesn’t appear in textbooks, including natural pronunciation, intonation, and slang. Additionally, some creators are Japanese speakers, offering videos that present English from a learner’s perspective.

Yes. Even just listening alone can significantly improve your English listening skills. The videos are full of expressions and gestures, making it easier to intuitively understand the meaning of English. However, if you want to improve your pronunciation and conversational skills, it’s most effective to combine watching with speaking practice.

Your pronunciation, fluency, and response speed are scored by AI and displayed as metrics “SIL” and “VTX” This allows you to visualize your strengths and weaknesses and track your progress with concrete data. All records are saved automatically, so you can see your improvement by comparing past scores.
