European CEFR Words Study

CEFR (Common European Framework of Reference for Languages) is the international standard for measuring language proficiency, from beginner (A1) to advanced (C2).

This app helps you study vocabulary for all CEFR levels, track your progress, and practice efficiently. Build your English step by step, improve reading and speaking skills, and achieve your language goals—anytime, anywhere.

The key to language learning is repeated listening. Just as a young child learns by listening again and again before ever writing, you too need an app that lets you practice repeated listening with accurate pronunciation. Without it, even after 10 years of study, you may find yourself stuck in the same place.

We designed this app with convenient repeated listening at its core.

You'll build your vocabulary through repeated listening with clear pronunciation, example sentences, and idioms; reinforce memorization with thorough review; and strengthen comprehension through repeated listening with English-to-English explanations as well as repeated listening and reading of 312 Aesop’s Fables. We take pride in delivering the most effective learning experience.

If you keep listening, your tongue and hand will follow. Listening, speaking, and writing will move forward together like three wheels. The first wheel is repeated listening.
