ChunkFlow is designed for French learners, utilizing the "chunk-learning method": Instead of focusing on isolated vocabulary, it centers on the real-world expressions you struggle to say. You will extract, understand, and accumulate reusable French chunks and sentences within context, gradually making your speaking more natural and fluent. Core Learning Path: 1.Explore Conversations → Correct and extract collectible chunks and natural expressions from real interactions. 2.Understand First → Clarify "how to say it and how to pronounce it" through syntax analysis and pronunciation practice. 3.Memorize Later → Review chunks and sentences with flashcards, ensuring your learning directly serves your speaking ability. 4.Continuous Accumulation → Bring practiced content into your next conversation, consolidating it through cyclical use. The more you use it, the smoother it gets. During your learning process, you can long-press any word to view its vocabulary card and pronunciation tips; flip the flashcards to see syntax analysis; and review practiced words and grammar questions on the summary page to prepare for the next round of practice. You can experience the app without a subscription. Once your trial quota is exhausted, you can unlock more benefits by subscribing through the App Store.

Available in English, Japanese, Chinese, Korean, Spanish, French, German, Italian and Portuguese, with more languages on the way. ■ Diagnose first, then plan A placement test measures listening, reading, grammar, vocabulary, writing and speaking on the CEFR scale. Tell it your goal and it writes a phased, week-by-week plan. Details like how much time you have can be added in chat later, and the plan adjusts. ■ Every lesson sits just above your level Grammar, vocabulary, reading, listening and speaking, one block at a time. Accuracy and time spent shape the difficulty and length of the next lesson. Words and grammar points due for review are woven into lessons before you forget them. ■ Miss a question, get it explained in your language Explanations come in your language. Still unsure? Ask the tutor right there — "why an, not the?", "why would, if it's the future?" — and keep asking until it clicks. The mistake notebook keeps the question, the answer, the why and the whole conversation, with similar questions to practice as often as you like. ■ Listening and speaking Listening uses natural multi-speaker dialogues. Speaking records you reading aloud and scores pronunciation and intonation (recordings are scored, not stored). ■ Progress you can see A six-skill radar, phase completion, study days, streaks and badges. Parents get a weekly report and a PIN-protected guardian space. ■ Price Everything is free for the first 30 days.
