Learn Korean from the Korean you care about, or follow a complete TOPIK or KIIP curriculum. Flash Fluency runs on one loop: choose what you want to learn, study it until it sticks, then speak it. 1. SELECT Follow a curriculum: • TOPIK 10K: 10,000 words and 322 grammar points covering TOPIK levels 1 to 6 • KIIP: the vocab and grammar of KIIP levels 1 to 4 • Everyday 5K: the 5,000 most common Korean words plus core grammar Or turn anything into a lesson. Song lyrics, a news article, a drama script, your class notes. Paste in any Korean and Flash Fluency pulls out every vocab word and grammar point to teach you. 2. STUDY Every sentence introduces exactly one new concept, so you're never lost. Read it, hear it, fill it in. Spaced repetition brings each one back right before you'd forget it, and progress in one skill carries into the others. Then write real Korean with what you just learned. Every translation comes back with corrections, naturalness tips, and style notes, down to the particle. 3. SPEAK Get AI feedback on every syllable you say, covering every Korean pronunciation rule. Compare your recording to a native voice block by block, so you know exactly what to fix and how. NEW TO KOREAN? Start with the Hangul course, then move on to Korean Fundamentals. No prior Korean needed. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://www.flashfluency.net/privacy_policy
