FlashLearn CN — Your Mandarin Learning Companion Whether you're just starting to say "nǐ hǎo" or pushing toward advanced fluency, FlashLearn CN is the learning companion that grows with you. Structured around the official HSK framework, FlashLearn CN takes you from complete beginner all the way through HSK 6 — so you always know where you stand and what to learn next. LEARN THE RIGHT WORDS, IN THE RIGHT ORDER FlashLearn CN is built around China's official HSK curriculum — the internationally recognised standard for Mandarin proficiency. Every level is carefully organised into focused courses covering: • Vocabulary & Characters — Learn the essential words and how to write them • Tones & Pronunciation — Master the four tones that make Mandarin unique • Grammar & Sentence Patterns — Build sentences with confidence • Reading — Develop comprehension from simple passages to complex texts From everyday survival phrases at HSK 1 to nuanced, academic-level language at HSK 6, every lesson is purposeful and progressive. LESSONS THAT TEACH, QUIZZES THAT CEMENT Each course is made up of bite-sized lessons you can read in minutes. Lessons present vocabulary, grammar, and language patterns clearly — including character tables with pinyin and English translations, tone guides, and real example sentences. After each lesson, integrated quizzes put your skills to the test. Multiple-choice questions cover vocabulary, meaning, pronunciation, and usage — giving your brain the active recall it needs to retain what you've learned long-term. Tap any Chinese text to hear it spoken aloud in clear Mandarin audio. TRACK YOUR PROGRESS Stay motivated by watching your progress grow. FlashLearn CN tracks every lesson you complete and every course you finish, so you always know which levels you've mastered and which still need attention.

Verdict
The clearest difference is in-app purchases: 90 Day Korean at none against FlashLearn CN's 1. FlashLearn CN's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price and device support there is nothing between them.
